Description
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 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 may be programmed as alarm registers or used as free RAM space.
The remaining 240 bytes are free RAM locations.
