MOS INTEGRATED CIRCUIT
µPD61P24
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR REMOTE CONTROL TRANSMISSION
DESCRIPTION
The µPD61P24 is a 4-bit single-chip microcontroller for infrared remote controllers for TVs, VCRs, stereos, cassette
decks, air conditioners, etc.
As the µPD61P24 is user-programmable, it is ideal for evaluation of programs running in a µPD6124A or 6600A,
and for small-scale production of such systems.
The functions of the µPD61P24 are described in detail in the following User’s Manual. Be sure to read this
manual before designing your system.
µPD612X Series User’s Manual: IEP-1083
FEATURES
• Transmitter for programmable infrared remote control-
ler
• 19 types of instructions
• Instruction execution time: 17.6 µs (with 455-kHz ce-
ramic resonator)
• On-chip one-time PROM: 1002 × 10 bits
• Data memory (RAM) capacity : 32 × 5 bits
• 9-bit programmable timer: 1 channel
• I/O pins (KI/O): 8 pins
• Input pins (KI): 4 pins
• Serial input pins (S-IN): 1 pin
• Transmission-in-progress indication pin (S-OUT): 1
pin
• Transmit carrier frequency (REM)
fOSC/12, fOSC/8
• Standby operation (HALT/STOP mode)
• Low power consumption
• Current consumption in STOP mode (TA = 25°C)
1 µA MAX.
• Low-voltage operation: VDD = 2.2 to 5.5 V
Caution To use the NEC transmission format, ask NEC to supply the custom code.
Do no use R0 when using a register as an operand of the branch instruction.
