MSM58321 Datasheet Real Time Clock/calendar

Manufacturer: OKI Electric

Overview: ¡ Semiconductor MSM58321 ¡ Semiconductor REAL TIME CLOCK/CALENDAR.

Datasheet Details

The MSM 58321 is a metal gate CMOS Real Time Clock/Calendar with a battery backup function for use in bus-oriented microprocessor applications.

The 4-bit bidirectional bus line method is used for the data I/O circuit;

the clock is set, corrected, or read by accessing the memory.
