Product Summary

The PCF8583P is a clock and calendar chip, based on a 2048 bit static CMOS RAM organized as 256 words by 8 bits. Addresses and data of the PCF8583P are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register of the PCF8583P is incremented automatically after each written or read data byte. Address pin A0 is used for programming the hardware address, allowing the connection of two devices to the bus without additional hardware.
