Interface with most microcontrollers through a simple serial port

Simple 3-wire interface

TTL compatible (VCC = 5V)

Single-byte or multi-byte (burst mode) data transmission used for reading or writing clock or RAM data

Low-power operation can extend the operating time of the backup battery

It operates fully from 2.0V to 5.5V

The current consumption is less than 300nA at 2.0V

The 8-pin DIP and 8-pin SO packages significantly reduce the required space

Optional industrial temperature range: -40°C to +85°C, supporting operation in a variety of applications
