M41T93
Serial SPI bus RTC with battery switchover
Features
Ultra-low battery supply current of 365 nA
Factory calibrated accuracy ±5 ppm
guaranteed 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)
–M41T93S: VCC = 3.0 V to 5.5 V
(2.85 V
≤ VRST ≤ 3.00 V)
–M41T93R: VCC = 2.7 V to 5.5 V
(2.55 V
≤ VRST ≤ 2.70 V)
–M41T93Z: VCC = 2.38 V to 5.50 V
(2.25 V
≤ VRST ≤ 2.38 V)
Compatible with SPI bus serial interface
(supports SPI mode 0 [CPOL = 0, CPHA = 0])
Programmable alarm with interrupt function
(valid even during battery back-up mode)
Optional 2nd programmable alarm available
Square wave output (defaults to 32 KHz on
power-up)
RESET (RST) output
Watchdog timer
Programmable 8-bit counter/timer
7 bytes of battery-backed user SRAM
Battery low flag
Power-down time stamp (HT bit)
Low operating current of 80 A
Oscillator stop detection
Battery or SuperCap backup
Operating temperature of –40 °C to +85 °C
Package options include:
– a 16-lead QFN or an 18-lead embedded
crystal SOIC
RoHS compliance: lead-free components are
compliant with the RoHS directive
SOX18 (MY, 18-pin, 300 mil SOIC
QFN16, 4 mm x 4 mm (QA)
with embedded crystal)
