The PCF8583 is a clock and calendar chip, based on a 2048 bit static
CMOS1 RAM 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.
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 can be programmed as alarm registers or used as free RAM space.
The remaining 240 bytes are free RAM locations.
