PCF8583 is a clock and calendar IC based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. It involves transferring addresses and data serially through the two-line bidirectional I2C-bus. The integrated 32.768 kHz oscillator circuit and the first 8 bytes of the RAM are used for the clock/calendar and counter functions. The next 8 bytes may be programmed as alarm registers or used as free RAM space. The remaining 240 bytes are free RAM locations.
