General Description
The MM58167Bisalow threshold metal gate CMOS circuit
that functionsas areal time clockinbus oriented microproc-
essor systems. The device includesan addressable real
time counter,56bitsof RAM,andtwo interrupt outputs.A
POWER DOWN input allowsthe chiptobe disabled from
therestofthe systemfor standbylow power operation.The
time baseisa 32.768kHz crystal oscillator.
Features Microprocessor compatible (8-bit data bus) Milliseconds through month counters56 bitsof RAM with comparatorto comparethe real
time countertothe RAM data2 INTERRUPT OUTPUTS with8 possible interrupt
signals POWER DOWN input that disablesall inputs and out-
puts exceptforoneofthe interrupts Statusbitto indicate rollover duringa read 32.768kHz crystal oscillator Four-year calendar(no leap year) 24-hour clock
