Overview
Description
The bq4802Y/bq4802LY real-time clock is a low-power microprocessor peripheral that integrates a time-of-day clock, a century-based calendar, and a CPU supervisor. It is available in 28-pin SOIC, TSSOP, and SNAPHAT package options, and requires the bq48SH-28x6 to complete the two-piece module. The bq4802Y/bq4802LY is ideal for applications such as fax machines, copiers, industrial control systems, point-of-sale terminals, data loggers, and computers.

Features
Real-time clock counts seconds through centuries in BCD format
On-chip battery-backup switchover circuit with nonvolatile control for external SRAM
Less than 500 nA of clock operation current in backup mode
Microprocessor reset with push-button override
Independent watchdog timer with programmable time-out period
Power-fail interrupt warning
Programmable clock alarm interrupt active in battery-backup mode
Programmable periodic interrupt
Battery-low warning

Applications
Telecommunications base stations
Servers
Handheld data collection equipment
Medical equipment
Handheld instrumentation
Test equipment
