Features & Applications

The PCF8593 is a CMOS1 clock and 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 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.

Features and benefits:

  • I2C-bus interface operating supply voltage: 2.5 V to 6.0 V
  • Clock operating supply voltage 1.0 V to 6.0 V at 0 °C to +70 °C
  • 8 bytes scratchpad RAM (when alarm not used)
  • Data retention voltage: 1.0 V to 6.0 V
  • External RESET input resets I2C interface only
  • Operating current (at fSCL = 0 Hz, 32 kHz time base, VDD = 2.0 V): typical 1 μA
  • Clock function with four year calendar
  • Universal timer with alarm and overflow indication
  • 24 hour or 12 hour format
  • 32.768 kHz or 50 Hz time base
  • Serial input and output bus (I2C-bus)
  • Automatic word address incrementing
  • Programmable alarm, timer, and interrupt function
  • Space-saving SO8 package available
  • Slave addresses: A3h for reading, A2h for writing
