PCF8593
Datasheet
General description
The PCF8593 is a CMOS clock/calendar circuit, optimized for low power consumption. 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. The built-in 32.768 kHz oscillator circuit and the first 8 bytes of 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.
Features
- I2C-bus interface operating supply voltage: 2.5 to 6.0 ? Clock operating supply voltage (Tamb =0 to +70°C): 1.0 to 6.0 V
- 8 bytes scratchpad RAM (when alarm not used)
- Data retention voltage: 1.0 to 6.0 V
- External RESET input resets I2C interface (only)
- Operating current (fscl = 0 Hz, 32 kHz time base, VDD = 2.0 V): typ. 1 µA
- Clock function with four year calendar
- Universal timer with alarm and overflow indication
- 24 or 12 hour format
- 32.768 kHz or 50 Hz time base
- Serial input/output bus (I2C-bus)
- Automatic word address incrementing
- Programmable alarm, timer and interrupt function
- Space-saving SO8 package available
- Slave address:
- READ A3
- WRITE A2.
