GENERAL DESCRIPTION

CTM8B5X series is an EPROM based 8-bit micro-

controller which employs a full CMOS technology

enhanced with low-cost, high speed and high noise

immunity. Watchdog Timer, RAM, EPROM, tri-state

I/O port, power down mode, and real time program-

mable clock/counter are integrated into this chip.

CTM8B5X contains 33 instructions, all are single

cycle except for program branches which take two

cycles.

On chip memory is available with 512x14 bits of

EPROM for CTM8B54E/55E, 1Kx14 bits of EPROM

for CTM8B56E, 2Kx14 bits of EPROM for

CTM8B57E and 24 to 72 bytes of static RAM.

2Kx14 bits for CTM8B57E.

• Internal RAM size : 25 bytes for CTM8B54E/56E,

24 bytes for CTM8B55E,

•

72 bytes for CTM8B57E.

• Direct and indirect addressing modes for data accessing

• 8-bit real time clock/counter with 8-bit programmable

prescaler.

• Internal power-on Reset.

• Device Reset Timer.

• Code protection.

• Sleep mode for power saving.

• On chip Watchdog Timer(WDT) based on internal RC

oscillator.

• Three I/O ports PA, PB nad PC with independent direc-

tion control.
