Product Summary

The M41T81M6F is a Serial Access timekeeper SRAM. The M41T81M6F is a low power Serial RTC with a built-in 32.768 KHz oscillator (external crystal controlled). Eight bytes of the SRAM (see Table 10, page 16) are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. An additional 12 bytes of SRAM provide status/control of Alarm, Watchdog and Square Wave functions. Addresses and data are transferred serially via a two line, bi-directional I2C interface.
