- Description
The M41TC8025 is a serial I2C real-time clock (RTC) incorporating temperature pensation to maintain accurate timekeeping over the industrial temperature range of -40 to +85 °C. In addition to providing date and time (seconds, minutes, hours, day-of-week, date (day of month), month and year), the device also provides an alarm function, fixed-cycle timer, time update interrupt and programmable frequency outputs (1 Hz, 1 KHz and 32 KHz). The M41TC8025 is provided in a 200 mil, 14-pin SOIC package.
