Product Summary

The PCF8583P is a clock/calendar circuit based on a 2048-bit static CMOS RAM. The PCF8583P is organized as 256 words by 8 bits. Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register 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.
