IZE4442 - INTELLIGENT 256-BYTE EEPROM

Description

The IZE4442 consists of 256 x 8 bit EEPROM main memory and a 32-bit protection memory with PROM functionality.

The main memory is erased and written byte by byte.

When erased, all 8 bits of a data byte are set to logical one.

Features

  • 256 x 8-bit EEPROM organization.
  • Byte-wise addressing.
  • Irreversible byte-wise write protection of lowest.
  • 32 addresses (Byte 031).
  • 32 x 1-bit organization of protection memory.
  • Two-wire link protocol.
  • End of processing indicated at data output.
  • Answer-to-Reset ace. to ISO standard 7816-3.
  • Programming time 2.5 ms per byte for both erasing.
  • and writing.
  • Minimum of 104 write/erase cycles1).
