Description

The M41TC8025 is a serial I2C real-time clock

(RTC) incorporating temperature compensation to

maintain accurate timekeeping over the extended

temperature range of -45 to +70 °C or 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.
