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

• Data memory (RAM):
32 × 4 bits
• On-chip carrier generator for infrared remote control
• 9-bit programmable timer:
1 channel
• Instruction execution time:
16 µs (when operating at fX = 4 MHz: ceramic oscillation)
• Stack levels:
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):
2
• S1/LED pin (I/O):
1 (when in output mode, this is the remote control transmission display
pin.)

VDD = 2.0 to 3.6 V
• Operating ambient temperature: TA = –40 to +85°C
• Oscillation frequency:
fX = 2.4 to 8 MHz
• On-chip POC circuit
APPLICATIONS
Infrared remote control transmitters (for AV and household electric appliances)
