IS23SC4442 - 256 BYTE EEPROM

General Description

IS23SC4442 contains 256 x 8 bits of EEPROM main memory and a 32 x 1 bit protection PROM memory.

The main memory can be randomly accessed byte by byte.

During memory erase, all 8 bits of a byte are set to logical one.

Key Features

  • Standard CMOS process.
  • 256 x 8 bits EEPROM organization.
  • Byte-wise addressing.
  • Irreversible byte-wise write protection of lowest 32 address (Byte 0..31).
  • 3-byte Programmable Security Code (PSC) for memory write/erase protection.
  • 2.7-5.5V power supply for read and write/erase.
  • Low power operation: 3 mA typical active current.
  • 2.5 ms programming time.
  • 2-wire serial interface www. DataSheet4U. com ISSI.
