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.

5. DATA POINTER (R0)
R0 (R10, R00) for the data memory can serve as the data pointer for the ROM.
R0 specifies the low-order 8 bits in the ROM address. The high-order 2 bits in the ROM address are specified
by the control register.
Table referencing for ROM data can be easily executed by calling the ROM contents by setting the ROM address
to the data pointer.
On reset or “all clear” is input, it becomes undefined.

6. ACCUMULATOR (A) ……… 4 BITS
The accumulator (A) is a 4-bit register. The accumulator plays a major role in each operation.
On reset or “all clear” is input, it becomes undefined.

7. ARITHMETIC LOGIC UNIT (ALU) ……… 4 BITS
The arithmetic logic unit (ALU) is a 4-bit operation circuit, and executes simple operations, such as arithmetic
operations.
8. FLAGS
(1) Status flag
When the status for each pin is checked by the STTS instruction, if the condition coincides with the condition
specified by the STTS instruction, the status flag (F) is set (to 1).
On reset or “all clear” is input, it becomes undefined.
(2) Carry flag
When the INC (increment) instruction or the RL (rotate left) instruction is executed, if a carry is generated from
the MSB for the accumulator, the carry flag (C) is set (to 1).
The carry flag (C) is also set (to 1), if the contents for the accumulator are “FH”, when the SCAF instruction
is executed.
On reset or “all clear” is input, it becomes undefined.
