M41T00M6F Real-Time Clock (RTC) ICs by STMicroelectronics

Serial real-time clock (RTC)


The M41T00 is a low power serial real-time clock with a built-in 32.768 kHz oscillator (external crystal controlled). Eight 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 WRITE or READ data byte. The M41T00 clock has a built-in power sense circuit which detects power failures and automatically switches to the battery supply during power failures. The energy needed to sustain the RAM and clock operations can be supplied from a small lithium coin cell. Typical data retention time is in excess of 5 years with a 50 mA/h 3 V lithium cell. The M41T00 is supplied in an 8-lead plastic small outline package.
