DS12887A+ General Description

The DS12887A+ is a popular RTC chip designed to provide accurate timekeeping and calendar functions. It combines a 32.768 kHz quartz crystal oscillator with non-volatile RAM (NVRAM) to store time, date, and configuration data even when the power is removed. This makes it suitable for a wide range of applications where precise timekeeping is required.

Key Features

Drop-in replacement for IBM AT computer clock/calendar
Binary or BCD time representation
Selectable Intel or Motorola bus timing
Interfaced with software as 128 RAM locations
14 Bytes of clock and control registers
Interrupt output with three independently maskable interrupt flags
Time-of-day alarm once per second to once per day
Periodic rates from 122µs to 500ms
End-of-clock update cycle flag
Programmable square-wave output

Automatic power-fail detect and switch circuitry

Application

Embedded Systems
Network Hubs, Bridges, and Routers
Security Systems
Utility Meters
