µ

PD754144, 754244

4-BIT SINGLE-CHIP MICROCONTROLLERS

DESCRIPTION

The

µ

PD754244 is a 4-bit single-chip microcontroller which incorporates the EEPROM

TM

for key-less entry

application.

It incorporates a 16

×

8-bit EEPROM, a 4-Kbyte mask ROM to store software, a 128

×

4-bit RAM to store the

processing data, a processing CPU, and a carrier generator which easily outputs waveforms for infrared remote

controller.

The details of functions are described in the following user’s manual. Be sure to read it before designing.

mean the

µ

PD754144.

The

µ

PD754144 and

µ

PD754244 differ in the notation of their RC oscillation: whenever f

X

(RC oscillation notation

for

µ

PD754244) is described, f

CC

should be substituted for the

µ

PD754144.
