M41T11M6F Description

The M41T11M6F is a low-power serial real-time clock (RTC) with 56 bytes of NVRAM. A built-in 32.768 kHz oscillator (external crystal controlled) and the first 8 bytes of the RAM are used for the clock/calendar function and are configured in binary-coded decimal (BCD) format. Addresses and data are transferred serially via a two-line bidirectional bus. The built-in address register is incremented automatically after each writes or reads a data byte.
