27C04A - 4K (512 x 8) CMOS EEPROM

General Description

The Microchip Technology Inc.

28C04A is a CMOS 4K non-volatile electrically Erasable and Programmable Read Only Memory (EEPROM).

The 28C04A is accessed like a static RAM for the read or write cycles without the need of external components.

Key Features

  • Fast Read Access Time.
  • 150 ns.
  • CMOS Technology for Low Power Dissipation - 30 mA Active - 100 µA Standby.
  • Fast Byte Write Time.
  • 200 µs or 1 ms.
  • Data Retention >200 years.
  • Endurance - Minimum 104 Erase/Write Cycles - Automatic Write Operation - Internal Control Timer - Auto-Clear Before Write Operation - On-Chip Address and Data Latches.
  • Data Polling.
  • Chip Clear Operation.
  • Enhanced Data Protection - VCC Detecto.
