# Part 1
## Introduction
The T5577 is a generic LF (Low Frequency) RFID card the is used in the
125 Khz frequency. It is a good card to use to learn about RFID and
learn how to use the proxmark3.
It is highly recommend that when learning about RFID that learning how
to read the data sheets be near the top of the list. It can be very hard
as the data sheet will hold the information you need, but you don’t yet
know what it means. As such, I will attempt to point to sections of the
data sheet and would highly advise that you look at the data sheet as
you go. Overtime the data sheet may change, as a result things may not
always be reference correctly.
As at writing this guide, the data sheet can be found at :
<http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-9187-RFID-ATA5577C_Datasheet.pdf>
This guide is not a how do I clone document. It is meant to help people
learn how to use the T5577 and in the process learn about rfid and the
proxmark3.
Throughout this guide I will give examples. It is recommended that you
try these as we go. To do so, have a blank T5577 card that you can use
for this purpose.
## T5577 Overview
The T5577 is a chip that can hold data and a configuration (Section
4.12).
In the diagram below, all white blocks can hold data. Some can be used
for a second purpose, such as the ‘password’ and ‘traceability data’.
The ‘Configuration Data’ and ‘Analog front end option setup’ will tell
the chip how to behave.
![](./media/image1.png)
## What data is on my T5577
Let’s have a look and see what a card might look in the proxmark3
software. Since we can change the configuration of how the T5577 will
output data, the proxmark3 software need to work out how to interpreted
the data it receives, we do this with the following command.
It should be noted that the T5577 has many clones. As such the default
setup of each card may be different. If the tractability data is
present, then this will vary based on the batch of cards.
Always run this command when you place a t5577 on the proxmark3. In all
examples shown, it will be assumed you have run the detect command.
```
proxmark3 > lf t55xx detect
```
You should see a results simular to the following:
```
Chip Type : T55x7
Modulation : ASK
Bit Rate : 2 - RF/32
Inverted : No
Offset : 31
Seq. Term. : No
Block0 : 0x00088040
```
Now that the proxmark3 has detected a T55x7 chip, and found some
information about it, we should be able to see all the data on the chip.
```
proxmark3 > lf t55xx dump
```
Your results should look similar to the following:
```

```
I will cover the meaning of this data as we go, but for now, lets keep
it simple.
## Read and Write Blocks of Data
The basic function of using the proxmark3 with rfid cards is to read and
write data. This reading and writing must be done in the correct way
needed for the chip (and its configuration). Lucky for us, the
developers have done a great job and gave us commands. What we need to
know is that with the T5577 data is read/written one complete block at a
time. Each block holds 32 bits of data (hence the binary output shown)
Since we know that the card has data and configuration blocks, lets say
away from those while we learn how to read and write. I suggest you
follow along and perform each command and check the results as we go.
We can store our own data in blocks 1-7 (remember that block 7 will be
needed if we want to set a password).
(Don’t forget to run the detect command: lf t55xx detect, and ensure you
can see the card)
1) Check what is stored in block 1. The following command can be read
as, run a low frequency (lf) command for the T55xx chip (t55xx) and
read block (b) number 1.
```
proxmark3\> lf t55xx read b 1
```
result:
```

blk | hex data | binary
----+----------+---------------------------------
1 | FFFFFFFF | 11111111111111111111111111111111
```
Note: Depending on the history of your card your data may vary, but
should match the dump data.
2) Write some new data into block 1 on the card.
We use the d option to supply the data ‘12345678’
```
proxmark3\> lf t55xx write b 1 d 12345678
```
result:
```
Writing page 0 block: 01 data: 0x12345678
```
3) Now, lets check if the data was written.
```
proxmark3> lf t55xx read b 1
```
result:
```
Reading Page 0:
blk | hex data | binary
----+----------+---------------------------------
1 | 12345678 | 00010010001101000101011001111000
```
4) The data is written in Hexadecimal. A single hex digit holds 4 bits
of data. So to store 32 bits in a block we need to supply 8 hex
digits (8 \* 4 = 32). If you are familiar with hex and binary do a
little bit of home work to learn. The following is a quick start.
| Hex | Binary | Decimal |
|:---:|:------:|:-------:|
| 0 | 0000 | 0 |
| 1 | 0001 | 1 |
| 2 | 0010 | 2 |
| 3 | 0011 | 3 |
| 4 | 0100 | 4 |
| 5 | 0101 | 5 |
| 6 | 0110 | 6 |
| 7 | 0111 | 7 |
| 8 | 1000 | 8 |
| 9 | 1001 | 9 |
| A | 1010 | 10 |
| B | 1011 | 11 |
| C | 1100 | 12 |
| D | 1101 | 13 |
| E | 1110 | 14 |
| F | 1111 | 15 |
To use all the bits we supply the data in Hex format and it will
always be 8 hex digits.
Lets try and write 89ABCDEF
```
proxmark3> lf t55xx write b 1 d 89abcdef
```
result:
```
Writing page 0 block: 01 data: 0x89ABCDEF
```
and check
```
proxmark3> lf t55xx read b 1
```
result:
```
Reading Page 0:
blk | hex data | binary
----+----------+---------------------------------
1 | 89ABCDEF | 10001001101010111100110111101111
```
### Exercise 1
Using the read and write commands you have learnt see if you can make
the lf t55 dump command show the following data for blocks 1-7 (Page 0).
Do not write to block 0 or try and change the data on page 1.
```
proxmark3\> lf t55 dump
```
result:
```

Practice reading and writing to blocks 1 to 7 until you are happy you
can do it and get the results you wanted (i.e. the data you want stored
is written to the block you want it stored in).
## How do I use a password
This can be a little tricky for beginners.
***If you forget your password you will lose access to your card***.
To tell the T5577 to use a password we have to change the data in the
configuration block (0). To help learn this and make it as simple as I
can, please read and follow exactly. If your results DON’T match 100% as
required, please do not proceed.
1) Lets start with a known card state and wipe the card. This will set
a default configuration to block 0 and set all the data in blocks
1-7 to a default.
```
proxmark3> lf t55xx wipe
```
Result:
```
Beginning Wipe of a T55xx tag (assuming the tag is not password
protected)
Writing page 0 block: 00 data: 0x00088040 pwd: 0x00000000
Writing page 0 block: 01 data: 0x00000000
Writing page 0 block: 02 data: 0x00000000
Writing page 0 block: 03 data: 0x00000000
Writing page 0 block: 04 data: 0x00000000
Writing page 0 block: 05 data: 0x00000000
Writing page 0 block: 06 data: 0x00000000
Writing page 0 block: 07 data: 0x00000000
```
2) Check that the card is in the desired state.
```
proxmark3> lf t55xx detect
```
result:
```
Chip Type : T55x7
Modulation : ASK
Bit Rate : 2 - RF/32
Inverted : No
Offset : 31
Seq. Term. : No
Block0 : 0x00088040
```
If block 0 does not hold the hex data **0x00088040 resolve this
first before proceeding.**
3) Set the password we want to use. For this example lets use the
password : ***12345678***
The password is saved in block 7 of page 0.
```
proxmark3> lf t55xx write b 7 d 12345678
```
result:
```
Writing page 0 block: 07 data: 0x12345678
```
4) Lets verify both block 0 and block 7
```
proxmark3> lf t55xx dump
```
result:
```

6 | FFFFFFFF | 11111111111111111111111111111111
7 | 12345678 | 00010010001101000101011001111000
Reading Page 1:

2 | 2D782308 | 00101101011110000010001100001000
3 | FFFFFFFF | 11111111111111111111111111111111
```
***Important : If block 0 and block 7 don’t match exactly, do not continue.***
5) Now we have a known configuration block and a known password of
12345678, we are ready to tell the card to use the password.
To do this the datasheet tells us we need to set the 28<sup>th</sup>
bit “PWD”. Check your datasheet and see the entire table (remember
the data sheet is your friend).
![](./media/image2.png)
We will cover other things in the configuration later. But the key
note here is we ONLY want to change bit 28 and nothing else.
Current Block 0 : ***00088040***
New Block 0 : ***00088050***
To understand what happened to get from 00088040 to 00088050 we need
to look at the binary data.
While this can be confusing it is important to understand this as we
do more advanced things.
Bit Location (28)
000000000011111111112222222 ***2*** 2233
123456789012345678901234567 ***8*** 9012
| Hex Data | Binary Data |
|:--------:|:---------------------------------------|
| 00088040 | 000000000000100010000000010***0***0000 |
| 00088050 | 000000000000100010000000010***1***0000 |
See how in the above we change the bit in location 28 from a 0 to 1
0 = No Password, 1 = Use Password
Note how we did NOT change any other part of the configuration, only bit 28.
To re-cap.
We put the card into a known configuration Block 0 : 00088040
We set the a known password Block 7 : 12345678
We altered the config data to tell the T5577 to use the password.
New Block 0 : 00088050
If you have completed all steps and have the exact same results, we are
ready to apply the new configuration.
```
proxmark3> lf t55xx write b 0 d 00088050
```
result:
```
Writing page 0 block: 00 data: 0x00088050
```
6) Lets check what happens when the password is set.
```
proxmark3> lf t55 detect
```
result:
```
Could not detect modulation automatically. Try setting it manually
with 'lf t55xx config'
```
Note how the lf t55 detect no longer seems to work\!
In this case, this is due to needing a password to read/write to the
card.
Lets try again, but this time supply the password. We use the option
p followed by the password.
```
proxmark3> lf t55 detect p 12345678
```
result:
```
Chip Type : T55x7
Modulation : ASK
Bit Rate : 2 - RF/32
Inverted : No
Offset : 31
Seq. Term. : No
Block0 : 0x00088050
```
7) Write a block of data with a password
```
proxmark3> lf t55xx write b 1 d 1234abcd p 12345678
```
result:
```
Writing page 0 block: 01 data: 0x1234ABCD pwd: 0x12345678
```
8) Read a block of data with a password
***\*\*\*\* Important \*\*\*\****
***Reading a T5577 block with a password when a password is not
enabled can result in locking the card. Please only use read with a
password when it is known that a password is in use.***
The proxmark3 has a safety check\!
```
proxmark3\> lf t55xx read b 1 p 12345678
```
result:
```
Reading Page 0:
blk | hex data | binary
----+----------+---------------------------------
Safety Check: Could not detect if PWD bit is set in config block.
Exits.
```
Note that the proxmark3 did not read the block, the safty kicked in
and wants us to confirm by supply the override option ‘o’.
Lets try again with the ‘o’ option as we know the password is set.
```
proxmark3> lf t55xx read b 1 p 12345678 o
```
result:
```
Reading Page 0:
blk | hex data | binary
----+----------+---------------------------------
Safety Check Overriden - proceeding despite risk
1 | 1234ABCD | 00010010001101001010101111001101
```
This time, we can see the data we wrote to block 1 is found with the
read command.
9) Remove the need to supply the password.
To do this we need to clear Bit 28 (set to 0) in the config. We have
this from above.
Remember if we don’t know the config and write this config to the
card, it will over write all other settings. This can recoved the
card, but will lose any settings you may want. So it’s a good idea
to read the config, and set bit 28 to 0, rather than just overwrite
the config and change the way the card works.
In our examples we know what it should be : 00088040
```
proxmark3> lf t55xx write b 0 d 00088040 p 12345678
```
result:
```
Writing page 0 block: 00 data: 0x00088040 pwd: 0x12345678
```
Now check if we can detect without a password
```
proxmark3> lf t55 detect
```
result:
```
Chip Type : T55x7
Modulation : ASK
Bit Rate : 2 - RF/32
Inverted : No
Offset : 31
Seq. Term. : No
Block0 : 0x00088040
```
Yes we can and we can see Block 0 is the correct config 00088040
# Part 2 – Configuration Blocks
One of the things a lot of people have trouble with or miss, is that the
T5577 has two different and separate communications protocols, each with
their own sub-protocols.
- Card to Reader
- Reader to Card
In Card to Reader, the T5577 will encode its data using the settings
from Block 0 in Page 0. It will use this in both default read mode
(where is sends out the blocks from 1 to x on power up), as well as when
it responds to commands.
In the Read To Card, the T5577 will encode the data using the settings
from Block 3 Page 1. If the command is not encoded correctly it will
ignore the command and revert back to default read mode.
## The configuration Block – Block 0 Page 0
For this configuration the settings chosen will be for the purpose of
the card when used in production. E.G. If you want the card to act like
an EM4100, then we need to choose the settings that work like the
EM4100; same goes for others like HID. I am not going to cover these
here, rather use an example. Others have collect these and posted on the
forum.
To get started lets look back at the tech sheet.
![](./media/image3.png)
The non-password protect EM4100 could have a block 0 config of 00148040,
so what does it mean.
To decode this config, we need to look at it in binary
00000000000101001000000001000000. Note that it had 32 bits and the
config block 0 is 32 bits. Now we can break it down.
| Bits | Purpose | Value |
| ------- | ---------------------- | ----------- |
| 0000 | Master Key | Nothing Set |
| 0000000 | Not used in Basic Mode | |
| 101 | Data Bit Rate | RF/64 |
| 0 | Not used in Basic Mode | |
| 01000 | Modulation | Manchester |
| 00 | PSKCF | RF/2 |
| 0 | AOR | Not Set |
| 0 | Not used in Basic Mode | |
| 010 | Max Block | 2 |
| 0 | Password | Not Set |
| 0 | ST Sequence Terminator | Not Set |
| 00 | Not used in Basic Mode | |
| 0 | Init Delay | Not Set |
To get more detail on each item, read through the data sheet.
Lets see how the proxmark3 can help us learn. We will assume the T5577
is in the same state from Part 1, where we can write to the card with no
password set (if not, review and get you card back to this state).
1) Lets turn you T5577 into an EM4100 with ID 1122334455
```
proxmark3> lf em 410xwrite 1122334455 1
```
result:
```
Writing T55x7 tag with UID 0x1122334455 (clock rate: 64)
#db# Started writing T55x7 tag ...
#db# Clock rate: 64
#db# Tag T55x7 written with 0xff8c65298c94a940
```
2) Check this has work.
```
proxmark3> lf search
```
result:

Looks good.
3) Now lest see what the T5577 detect and info shows
```
proxmark3> lf t55 detect
```
result:
```

```
```
proxmark3> lf t55 info

result:

```
We can see that the info gave us more information and confirmed what
we decoded by hand. But remember, the detect is still needed so the
proxmark3 software will know how to decode the info block.
We can see that for the EM4100 emulation we have two blocks of data
(Max Block = 2). On the T5577 these will be Blocks 1 and 2.
## Exercise 2
Using the skills form part 1, see if you can view the data in blocks 1 and 2.
Note: the EM4100 ID of 1122334455 is encoded, so don’t expect to see
those bytes as such. To learn how to do that, you guessed it, find the
datasheet and review.
At this point we have a EM4100 card. If we wanted to password protect
it, we can follow the password section and update the config from
00148040 to 00148050.
***Important : Don’t forget to set a valid password in block 7 and remember it.***
