ATA5558

1. General Description

The ATA5558 is a contactless, two-terminal R/W-Identification IC (IDIC

) for multi- or

single tag applications in the low frequency (≈ 125 kHz) range. The passive tag uses

the external RF signal to generate it’s own power supply and internal clock reference.

Memory

ATA5558

* Mask option

It contains an EEPROM which is subdivided into 1024 bits of user memory and

320 bits of system memory. Both memory sections are organized in data blocks of

32 bits, each equipped with an associated lock bit for block write protection. The user

memory, which is intended for storage of recallable user data, is made of 32 such

blocks. The 10 block system memory section is reserved for system parameter and

configuration settings. Two of these blocks include a 32 bit read and a 32 bit write

password to prevent unauthorized read and/or write access to protected user defin-

able memory pages.
