Product details

Description

1 Description The M41T6x is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator.Eight registers are used for the clock/calendar function and are configured in binary-coded decimal (BCD) format.Further eight registers provide status/control of alarm, 32 kHz output, calibration, and watchdog functions.Addresses and data are transferred serially via a two-line, bidirectional I²C interface.The built-in address register is incremented automatically after each WRITE or
