DATA SHEET
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.
µPD67, 67A, 68, 68A, 69 Data Sheet: U14935E
µPD67B, 68B Data Sheet:
U16792E
FEATURES
• Program memory (one-time PROM):
2026 × 10 bits
• Data memory (RAM):
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:
1 channel
• Instruction execution time:
16 µs (@ fX = 4 MHz)
• 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
www.DataSheet4U.coSmense 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)
• Power supply voltage:
VDD = 1.9 to 3.6 V
• Operating ambient temperature:
TA = –40 to +85°C
• Oscillator frequency:
fX = 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)
