Features & Applications

The M41T80M6F is a part of M41T series I2C RTC. It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOIC-8 Packaging.

The M41T80 is a low power Serial RTC with a built-in 32.768kHz oscillator (external crystal controlled). Eight registers (see Table 3: Clock register map on page 14) are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. An additional 12 registers provide status/control of Alarm, 32kHz output, and Square Wave functions. Addresses and data are transferred serially via a two line, bi-directional I2C interface. The built-in address register is incremented automatically after each WRITE or READ data byte.

Features:

  • Counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century
  • 32 kHz crystal oscillator integrating load capacitance (12.5pF) providing exceptional oscillator stability and high crystal series resistance operation
  • Serial interface supports I2C bus (400kHz)
  • 2.0 to 5.5V clock operating voltage
  • 32 kHz square wave on power-up to drive a microcontroller in low power mode
  • Programmable (1Hz to 32 kHz) square wave
  • Programmable Alarm and Interrupt function
  • Low operating current of 200µA
  • Operating temperature of -40 to 85˚C
  • ECOPACK® package available
