DATA SHEET
MOS INTEGRATED CIRCUIT
µPD6P4B
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
DESCRIPTION
The µPD6P4B 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 µPD6P4B, it is ideal for program evaluation and small-scale production
of the application systems using the µPD62, 63, 63A, or 64.
When reading this document, also refer to the µPD62 Data Sheet (U14208E) and the µPD63, 63A, 64 Data
Sheet (U11371E).
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
: 1 channel
• Command execution time
: 16 µs (when operating at fX = 4 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 (In output mode, this is the remote control transmission display
pin.)
• Power supply voltage
: VDD = 2.2 to 3.6 V (at fX = 4 MHz)
VDD = 2.7 to 3.6 V (at fX = 8 MHz)
• Operating ambient temperature : TA = –40 to +85 °C
• Oscillator frequency
: fX = 2.4 to 8 MHz
• POC circuit
APPLICATION
Infrared remote control transmitter (for AV and household electric appliances)
