Overview
The LM8562 is a digital clock-use LSI having features such as
easy setting, two alarms. Since the LM8562 is designed to be
able to direct drive an LED panel of duplex type, the package
in which the LM8562 is placed is a 28-pin shrink DIP with a
small mounting area.
Features
(1) Duplex LED display (LM8560-use LED panel usable)
(2) Two alarms on chip (600 Hz, 1200 Hz)
(3) Up, down/fast, slow time setting available (easy setting)
(4) 12/24-hour mode, 50/60 Hz selectable (provided that it is
impossible to select the combination of 24-hour mode and
60 Hz)
(5) On-chip CR oscillator for backup use at the time of power
failure
(6) Power failure indicator
(7) 59-minute alarm/sleep timer
(8) 6-minute snooze function
(9) Radio output function
(10) P-channel ED MOS
(11) Pin 28 dual-in-line shrink package
(12) Wide operating voltage/operating temperature range
