M41T94
Serial real-time clock with 44 bytes NVRAM and reset
Features
■ Counters for tenths/hundredths of seconds,
seconds, minutes, hours, day, date, month,
year, and century
■ 32 KHz crystal oscillator integrating load
capacitance (12.5 pF) providing exceptional
oscillator stability and high crystal series
resistance operation
■ Serial peripheral interface (2 MHz SPI)
■ Ultralow battery supply current of 500 nA (max)
■ 2.7 to 5.5 V operating voltage
■ 2.5 to 5.5 V oscillator operating voltage
■ Battery low flag
■ Automatic switchover and deselect circuitry
■ 44 bytes of general purpose RAM
■ Programmable alarm and interrupt function
(valid even during battery backup mode)
■ Accurate programmable watchdog timer (from
62.5 ms to 128 s)
■ Microprocessor power-on reset
■ Choice of power-fail deselect voltages
(VCC = 2.7 to 5.5 V):
–THS = VSS; 2.55 V ≤ VPFD ≤ 2.70 V
–THS = VCC; 4.20 V ≤ VPFD ≤ 4.50 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
■ RoHS compliant
– Lead-free second level interconnect
