M41T82
Overview
- Ultra-low battery supply current of 365 nA
- Factory-calibrated accuracy of ±5 ppm typical after 2 reflows (SOX18) - Much better accuracies achievable using built-in programmable analog and digital calibration circuits
- 2.0 V to 5.5 V clock operating voltage
- Counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century
- Automatic switchover and reset output circuitry (fixed reference) - M41T83S: VCC = 3.00 V to 5.50 V - M41T83R: VCC = 2.70 V to 5.50 V - M41T83Z: VCC = 2.38 V to 5.50 V
- Serial interface supports I2C bus (400 kHz protocol)
- Programmable alarm with interrupt function (valid even during battery backup mode) Datasheet - production data
- Optional 2nd programmable alarm available
- Square wave output defaults to 32 KHz on power-up (M41T83 only)
- RESET (RST) output
