PCF85102C-2
256 × 8-bit CMOS EEPROM with I
2
C-bus interface
Rev. 04 — 22 October 2004 Product data
1. Description
The PCF85102C-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 I
2
C-bus. Up to eight
PCF85102C-2 devices may be connected to the I
2
C-bus. Chip select is accomplished
by three address inputs (A0, A1 and A2).
