Mode Register
Modulator
Memory
ATA5577
The mode register maintains a readable shadow copy of the configuration data held in block 0 of
the EEPROM. It is continually refreshed during read mode and (re-)loaded after every POR
event or reset command. On delivery, the mode register is pre-programmed with default values
(see full version of the datasheet).
The modulator encodes the serialized EEPROM data for transmission to a tag reader or base
station. Several types of modulation are available including Manchester, bi-phase, FSK, PSK,
and NRZ.
Figure 4-2.
The memory is a 363-bit EEPROM, which is arranged in 11 blocks of 33 bits each. Each block
includes a single Lock bit, which is responsible for write-protecting the associated block. Pro-
gramming takes place on a block basis, so a complete block (including lock bit) can be
programmed with a single command. The memory is subdivided into two page areas. Page 0
contains 8 blocks and page 1 contains 4 blocks. All 33 bits of a block, including the lock bit, are
programmed simultaneously.
