MOS INTEGRATED CIRCUIT

µPD6P8, 6P8A, 6P8B

4-BIT SINGLE-CHIP MICROCONTROLLER

FOR INFRARED REMOTE CONTROL TRANSMISSION

DESCRIPTION

The µPD6P8, 6P8A, 6P8B are microcontrollers for infrared remote control transmitters and are provided with

a one-time PROM as the program memory.

Because users can write programs for the µPD6P8, 6P8A, 6P8B, They are ideal for program evaluation and small-

scale production of application systems that use the µPD67A, 67B, 68A, 68B.

When reading this document, also refer to the following documents.

µPD67B, 68B Data Sheet:

U16792E

FEATURES

• Program memory (one-time PROM):

• Data memory (RAM):

2026 × 10 bits

32 × 4 bits

• On-chip carrier generator for infrared remote control: The high-level and low-level width can be set separately

from 250 ns to 64 µs (@ fX = 4 MHz operation) via modulo

registers

• 9-bit programmable timer:

• Instruction execution time:

• Stack level:

1 channel

16 µs (@ fX = 4 MHz)

1 level (stack RAM is for data memory RF as well)

• I/O pins (K^I/O):

8 units

• Input pins (K^I):

4 units

• Sense input pins (S⁰, S2):

• S¹/LED pin (I/O):

2 units

1 unit (when in output mode, this is the remote control

transmission display pin)

V^DD= 1.9 to 3.6 V

• Power supply voltage:

• Operating ambient temperature:

• Oscillator frequency:

T^A= –40 to +85°C

f^X= 3.5 to 4.5 MHz

• On-chip POC circuit and RAM retention detector

• On-chip oscillator (µPD6P8B)

APPLICATIONS

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