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.

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 : 3 channels

• On-chip memory

• 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.
