DESCRIPTION

· The PCF8583 is a clock and calendar chip based on 2048-bit static CMOS RAM, organized as 256 words by 8 bits.
· It uses a two-line bidirectional I2C-bus for serial data and address transfer.
· Features include a built-in 32.768 kHz oscillator, 8 bytes for clock/calendar functions, and 240 bytes of free RAM.

FEATURES

· I2C-bus interface with an operating supply voltage of 2.5 V to 6 V.
· Clock operates from 1.0 V to 6.0 V at 0°C to +70°C.
· Includes 240×8-bit low-voltage RAM and a four-year calendar.
· Supports 24-hour or 12-hour formats with a 32.768 kHz or 50 Hz time base.
· Programmable alarm, timer, and interrupt functions with automatic word address incrementing.

APPLICATIONS

· Suitable for applications requiring precise timekeeping and calendar functions.
· Ideal for systems needing low-power, compact clock and calendar solutions.
· Can be used in devices that require programmable alarms and timers.
