General Description
MSM58321 General Description
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.
The time is read with 4-bit DATA I/O, ADDRESS WRITE, READ, and BUSY; it is written with 4-bit DATA I/O, ADDRESS WRITE,WRITE, and BUSY.
