Overview
The PCF85102C-2T/03:11, produced by NXP USA Inc., is a 256 x 8-bit CMOS Electrically Erasable Programmable Read Only Memory (EEPROM) with an I2C-bus interface. This device features non-volatile storage of 2 kbits, organized as 256 x 8-bit, and is designed for low power consumption using full CMOS technology. It includes an on-chip voltage multiplier and supports both byte and page write modes, as well as sequential and random read operations. The device is highly reliable, with internal redundant storage code to protect against single bit errors and a high endurance of 1,000,000 Erase/Write cycles.
