Description

The Microchip Technology Inc. 24FC32 is a 4K x 8 (32K bit) Serial Electrically Erasable PROM (EEPROM) with a high-speed 1 MHz SE2.bus whose protocol is functionally equivalent to the industry-standard I2C bus.

Features

• Voltage operating range: 4.5V to 5.5V

- Maximum write current 3 mA at 5.5V

- Maximum read current 150 µA at 5.5V

- Standby current 1 µA typical

• 1 MHz SE2.bus two wire protocol

• Self-timed write cycle (including auto-erase)

• Power on/off data protection circuitry
