SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 7544 Group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 7544 Group has a serial I/O, 8-bit timers, a 16-bit timer, and
an A-D converter, and is useful for control of home electric appli-
ances and office automation equipment.
FEATURES
Basic machine-language instructions ...................................... 71
The minimum instruction execution time ......................... 0.25
s
(at 8 MHz oscillation frequency, double-speed mode for the
shortest instruction)
Memory size ROM ......................................................... 8 K bytes
RAM ........................................................ 256 bytes
Programmable I/O ports ........................................................... 25
Interrupts ................................................. 12 sources, 12 vectors
Timers ............................................................................. 8-bit 2
...................................................................................... 16-bit 1
Serial I/O ...................... 8-bit 1 (UART or Clock-synchronized)
A-D converter ................................................. 8-bit 6 channels
