PCF8582C-2T/03

EEPROM SERIAL 2K, SMD, 8582, SOIC8; Memory Type: EEPROM; Interface Type: Serial, I2C; Memory Size: 2Kbit; Memory Conf...

The is a 256 x 8-bit CMOS floating gate Electrically Erasable Programmable Read-Only Memory EEPROM with I²C-bus interface and 2kB 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 EEPROM. 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 PCF8582C-2 devices may be connected to the I²C-bus. Chip select is accomplished by three address inputs. Timing of the E/W cycle is carried out internally, thus no external components are required. Programming time control PTC, pin-7, must be connected to either VDD or left open-circuit. There is an option of using an external clock for timing the length of an E/W cycle.
