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.
