PCF8582C-2T

256到1024 ×8位CMOS EEPROM的具有I2C总线接口 256 to 1024 x 8-bit CMOS EEPROMs with I2C-bus interface

Description

The PCF8582C-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.

Features
