SERIAL-INTERFACE REAL TIME CLOCK MODULE
Builtin crystal unit allows adjustment-free efficient operation.
The small package makes high-density mounting possible. (SOP 14-pin)
Automatic calendar function (year, month, day, day of the week, hour, minute,
second).
Automatic leap year correction. (up to 2099)
Builtin 30 x 4-bit S-RAM.
High-speed access.
Reference pulse output. (1024 Hz, 1/10 Hz)
Low current consumption. (1 μA typical)
Similar mounting method to that used for universal type SMD IC.
