General Description

The PT7C4338 serial real-time clock is a low-power clock/calendar with a programmable square-wave output and 56 bytes of nonvolatile RAM.

Address and data are transferred serially via a 2-wire, bidirectional bus.

Key Features

  • Using external 32.768kHz quartz crystal.
  • Supports I2C-Bus's high speed mode (400 kHz).
  • Includes time (Hour/Minute/Second) and calendar (Year/Month/Date/Day) counter functions (BCD code).
  • Programmable square wave output signal.
  • 56-byte, battery-backed, nonvolatile (NV) RAM for data storage.
  • Automatic power-fail detect and switch circuitry of battery backup.
  • UL Recognized: E348121 Product.
