Modulator
The modulator consists of data encoders for the following basic types of modulation:
Table 1.
Types of e5550-compatible Modulation Modes
Notes:
1. A common multiple of bitrate and FSK frequencies is recommended.
2. In PSK mode the selected data rate has to be an integer multiple of the PSK
sub-carrier frequency.
Memory
The memory is a 330-bit EEPROM, which is arranged in 10 blocks of 33 bits each. All 33
bits of a block, including the lock bit, are programmed simultaneously.
Block 0 of page 0 contains the mode/configuration data, which is not transmitted during
regular-read operations. Block 7 of page 0 may be used as a write protection password.
Bit 0 of every block is the lock bit for that block. Once locked, the block (including the
lock bit itself) is not re-programmable through the RF field again.
Blocks 1 and 2 of page 1 contain traceability data and are transmitted with the modula-
tion parameters defined in the configuration register after the opcode ’11’ is issued by
the reader (see Figure 11). These tracebility data blocks are programmed and locked by
Atmel.

Manchester
‘0’ = falling edge, ‘1’ = rising edge
Biphase
‘1’ creates an additional mid-bit change
