DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD64A, 65  
4-BIT SINGLE-CHIP MICROCONTROLLERS  
FOR INFRARED REMOTE CONTROL TRANSMISSION  
DESCRIPTION  
The µPD64A and 65 feature low-voltage 2.0 V operation, and incorporate a carrier generator for infrared remote  
control transmission, a standby release function through key entry, and a programmable timer, making them ideal  
for infrared remote control transmitters.  
A one-time PROM product, the µPD6P5 is also available for program evaluation or small-quantity production.  
FEATURES  
• Program memory (ROM)  
µPD64A: 1002 × 10 bits  
µPD65: 2026 × 10 bits  
• Data memory (RAM):  
32 × 4 bits  
• On-chip carrier generator for infrared remote control  
• 9-bit programmable timer:  
• Instruction execution time:  
• Stack levels:  
1 channel  
16 µs (when operating at fX = 4 MHz: ceramic oscillation)  
1 (stack RAM is also used for data memory RF)  
• I/O pins (KI/O):  
8
• Input pins (KI):  
4
• Sense input pin (S0, S2):  
• S1/LED pin (I/O):  
2
1 (when in output mode, this is the remote control transmission display  
pin.)  
• Power supply voltage:  
VDD = 2.0 to 3.6 V  
• Operating ambient temperature: TA = –40 to +85°C  
• Oscillation frequency:  
• On-chip POC circuit  
fX = 2.4 to 8 MHz  
APPLICATIONS  
Infrared remote control transmitters (for AV and household electric appliances)
