256 × 8-bit CMOS EEPROM with I2C-bus interface

Rev. 04 — 22 October 2004

Product data

1. Description

The PCF85103C-2 is a floating gate Electrically Erasable Programmable Read Only

Memory (EEPROM) with 2 kbits (256 × 8-bit) non-volatile storage. By using an

internal redundant storage code, it is fault tolerant to single bit errors. This feature

dramatically increases the reliability compared to conventional EEPROMs. Power

consumption is low due to the full CMOS technology used. The programming voltage

is generated on-chip, using a voltage multiplier.

Data bytes are received and transmitted via the serial I2C-bus. Up to eight

PCF85103C-2 devices may be connected to the I2C-bus. Chip select is accomplished

by three address inputs (A0, A1 and A2).

The PCF85103C-2 is identical to PCF85102C-2 except for the fixed I2C address,

allowing up to eight PCF85102C-2 and eight PCF85103C-2 on the same I2C-bus.
