DESCRIPTION
The 7544 Group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 7544 Group has a serial interface, 8-bit timers, a 16-bit timer,
and an A/D converter, and is useful for control of home electric ap-
pliances and office automation equipment.
FEATURES

...................................................................................... 16-bit 1
Serial interface ............ 8-bit 1 (UART or Clock-synchronized)
A/D converter ................................................. 8-bit 6 channels
Clock generating circuit ............................................. Built-in type
(low-power dissipation by an on-chip oscillator enabled)
(connect to external ceramic resonator or quartz-crystal oscilla-
tor permitting RC oscillation)
Watchdog timer ............................................................ 16-bit 1
Power source voltage
