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

µPD63, 63A, and 64 are suitable for

infrared remote control transmitters.

For the

µPD63, 63A and 64, we have made available the one-time PROM product µPD6P4B for program

evaluation or small-quantity production.

FEATURES

• Program memory (ROM)

µPD63 : 512 × 10 bits

µPD63A: 768 × 10 bits

µPD64 : 1002 × 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)

Unless otherwise stated, the

µPD63 is taken as a representative product in this document.
