描述 Description

The PCF8598C-2 is a floating gate Electrically Erasable Programmable Read Only Memory (EEPROM) with 8 kbits (1024 × 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 I2C-bus. Up to two PCF8598C-2 devices may be connected to the I2C-bus. Chip select is accomplished by one address input (A2).
