M41T94
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
■
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
■
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
(VCC = 2.7 to 5.5V):
–THS = VSS; 2.55V ≤VPFD ≤2.70V
–THS = VCC; 4.20V ≤VPFD ≤4.50V
■
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
