MOS INTEGRATED CIRCUIT
µPD62
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
DESCRIPTION
Equipped with low-voltage 1.8 V operation, a carrier generation circuit for infrared remote control transmission,
a standby release function through key entry, and a programmable timer, the µPD62 is suitable for infrared remote
control transmitters.
For the µPD62, we have made available the one-time PROM product µPD6P4B for program evaluation or small-
quantity production.
FEATURES
• Program memory (ROM): 512 × 10 bits
• Data memory (RAM): 32 × 4 bits
• Built-in carrier generation circuit for infrared remote control
• 9-bit programmable timer
: 1 channel
• Command execution time
: 8 µs (when operating at fX = 8 MHz: ceramic oscillation)
• Stack level
: 1 level (Stack RAM is for data memory RF as well.)
• I/O pins (KI/O)
: 8 units
• Input pins (KI)
: 4 units
• Sense input pin (S0)
: 1 unit
• S1/LED pin (I/O)
: 1 unit (When in output mode, this is the remote control transmission display
pin.)
• Power supply voltage
: VDD = 1.8 to 3.6 V (when operating at fX = 4 MHz)
VDD = 2.2 to 3.6 V (when operating at fX = 8 MHz)
• Operating ambient temperature : TA = –40 to +85 ˚C
• Oscillator frequency
: fX = 2.4 to 8 MHz
• POC circuit (Mask option)
APPLICATION
Infrared remote control transmitter (for AV and household electric appliances)
