Serial Real Time Clock with 44Bytes NVRAM and Reset

Feature summary

■ Counters for tenths/hundredths of seconds,

seconds, minutes, hours, day, date, month,

year, and century

■ 32KHz crystal oscillator integrating load

capacitance (12.5pF) providing exceptional

oscillator stability and high crystal series

resistance operation

SO16 (MQ)

■ Serial peripheral interface (2MHz SPI)

■ Ultra-low battery supply current of 500nA (max)

■ 2.7 to 5.5V operating voltage

■ 2.5 to 5.5V oscillator operating voltage

■ Battery low Flag

SNAPHAT (SH)

Battery & Crystal

■ Automatic switch-over and deselect circuitry

■ 44 bytes of general purpose RAM

■ Programmable Alarm and interrupt function

(valid even during battery back-up mode)

■ Accurate programmable Watchdog timer (from

62.5ms to 128s)

■ Microprocessor power-on reset

■ Choice of power-fail deselect voltages

SOH28 (MH)

(V = 2.7 to 5.5V):

– THS = V ; 2.55V ≤V

≤2.70V

≤4.50V

PFD

– THS = V ; 4.20V ≤V

■ Packaging includes a 28-lead SOIC and

SNAPHAT TOP (to be ordered separately) or

16-lead SOIC

■ 28-lead SOIC package provides direct

connection for a SNAPHAT TOP which

contains the battery and crystal
