34AA04 - EEPROM

General Description

The Microchip Technology Inc.

34AA04 is a 4 Kbit Electrically Erasable PROM which utilizes the I2C serial interface and is capable of operation across a broad voltage range (1.7V to 3.6V).

Key Features

  • 4 Kbit EEPROM: - Internally organized as two 256 x 8-bit banks - Byte or page writes (up to 16 bytes) - Byte or sequential reads within a single bank - Self-timed write cycle (5 ms max. ).
  • JEDEC® JC42.4 (EE1004-v) Serial Presence Detect (SPD) Compliant for DRAM (DDR4) modules.
  • High-Speed I2C™ Interface: - Industry standard 1 MHz, 400 kHz, and 100 kHz - Schmitt Trigger inputs for noise suppression - SMBus-compatible bus time out - Cascadable up to eight devices.
