The PCF8583 is a clock/calendar circuit based on a
2048-bit static CMOS RAM organized as 256 words by
8 bits. Addresses and data are transferred serially via the
two-line bidirectional I
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.
The built-in 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.
