RTC-62421/62423
Real time clock module
4-bit REAL TIME CLOCK MODULE
Builtin crystal unit allows adjustment-free efficient operation.
Low standby voltage and current consumption (1.8µA at 2V).
Wide range of operating temperature (from -40˚C to +85˚C).
24H/12H changeable and leap year automatically adjustable (gregorian
calendar).
Similar mounting method (RTC-62423) to that used for universal type SMD IC.
Pins and functions are compatible with the MSM6242 series.
