Overview
The PCF85103C-2T/00:11 is a 256 x 8-bit CMOS Electrically Erasable Programmable Read Only Memory (EEPROM) manufactured by NXP Semiconductors. This device features a floating gate EEPROM with 2 kbits of non-volatile storage, organized as 256 x 8-bit words. It is designed with an internal redundant storage code, making it fault tolerant to single bit errors, which significantly enhances its reliability compared to conventional EEPROMs. The device operates using full CMOS technology, ensuring low power consumption, and includes an on-chip voltage multiplier to generate the programming voltage.
The PCF85103C-2T/00:11 communicates via the serial I²C-bus interface, allowing up to eight devices to be connected on the same bus. Chip select is managed through three address inputs (A0, A1, and A2). This EEPROM is available in SO8 (SOT96-1) and DIP8 (SOT97-1) packages and is RoHS compliant.
