产品介绍
M41T94
Features
- 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 switchover 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
- RoHS compliant
- Lead-free second level interconnect
