PCF8593 Datasheet Low-power Clock/calendar

Manufacturer: NXP Semiconductors

Overview: PCF8593 Low power clock and calendar Rev. 5 — 24 January 2020 Product data sheet 1.

General Description

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.

Key Features

  • 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 A.
  • Clock function with four year calendar.
  • Universal timer with alarm and overflow indication.
  • 24 hour or 12 hour for.
