DATA SHEET
MOS INTEGRATED CIRCUIT
µPD754144, 754244
4-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD754244 is a 4-bit single-chip microcontroller which incorporates the EEPROMTM 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.
µPD754144, 754244 User’s Manual: U10676E
FEATURES
On-chip EEPROM: 16 × 8 bits (mapped to the data memory)
On-chip key return reset function for key-less entry
System clock oscillation circuit
µPD754144: RC oscillator (external resistor and capacitor)
µPD754244: Crystal/ceramic oscillator
Low-voltage operation: VDD = 1.8 to 6.0 V
Timer function (4 channels)
• Basic interval timer/watchdog timer: 1 channel
• 8-bit timer counter
On-chip memory
: 3 channels
• Program memory (ROM)
4096 × 8 bits
• Data memory (static RAM)
128 × 4 bits
Instruction execution time variable function suited for power saving.
µPD754144:
4, 8, 16, 64 µs (at fcc = 1.0-MHz operation)
µPD754244:
0.95, 1.91, 3.81, 15.3 µs (at fx = 4.19-MHz operation)
0.67, 1.33, 2.67, 10.7 µs (at fx = 6.0-MHz operation)
APPLICATIONS
Automotive appliances such as key-less entry, compact data carrier, etc.
Unless contextually excluded, references in this data sheet to the µPD754244 (crystal/ceramic oscillation: fX)
mean the µPD754144.
The µPD754144 and µPD754244 differ in the notation of their RC oscillation: whenever fX (RC oscillation notation
for µPD754244) is described, fCC should be substituted for the µPD754144.
