DATA SHEET

MOS INTEGRATED CIRCUIT

µPD61P34B

4-BIT SINGLE-CHIP MICROCONTROLLER

FOR INFRARED REMOTE CONTROL TRANSMISSION

DESCRIPTION

The µPD61P34B is a microcontroller for infrared remote control transmitters which is provided with a one-time

PROM as the program memory.

Because users can write programs for the µPD61P34B, it is ideal for program evaluation and small-scale

production of the application systems using the µPD6133 or 6134.

When reading this document, also refer to the µPD6133, 6134 Data Sheet (U10454E).

FEATURES

• Program memory (one-time PROM) : 1002 × 10 bits

• Data memory (RAM)

: 32 × 4 bits

• Built-in carrier generation circuit for infrared remote control

• 9-bit programmable timer

• Command execution time

• Stack level

: 1 channel

: 16 µs (when operating at fX = 500 kHz: ceramic oscillation)

: 1 level (Stack RAM is for data memory RF as well.)

• I/O pins (K^I/O)

: 8 units

• Input pins (KI)

: 4 units

• Sense input pin (S⁰)

• S¹/LED pin (I/O)

: 1 unit

: 1 unit (When in output mode, this is the remote control transmission

display pin.)

• Power supply voltage

• Operating ambient temperature

• Oscillator frequency

• POC circuit

: V^DD= 2.2 to 3.6 V

: T^A= –40 to +85 °C

: fX = 300 kHz to 1 MHz

APPLICATION

Infrared remote control transmitter (for AV and household electric appliances)
