Applications

Description

(RTC) incorporating temperature compensation 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.
