µPD6P5
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROL TRANSMISSION
The µPD6P5 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 µPD6P5, it is ideal for program evaluation and small-scale production
of the application systems using the µPD64A or 65.
When reading this document, also refer to the µPD64A, 65 Data Sheet (U14380E).
FEATURES
• Program memory (one-time PROM) : 2,026 × 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, S2)
: 2 units
• 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
• Operating ambient temperature : TA = –40 to +85 °C
• Oscillator frequency
: fX = 2.4 to 4.8 MHz
• POC circuit
APPLICATION
Infrared remote control transmitter (for AV and household electric appliances)

Function
These pins refer to the 8-bit I/O ports. I/O switching can
be made in 8-bit units.
In INPUT mode, a pull-down resistor is added.
In OUTPUT mode, they can be used as a key scan output
from key matrix.
3 S0
Refers to the input port.
Can also be used as a key return input from key matrix.
In INPUT mode, the availability of the pull-down resistor
of the S0 and S1 ports can be specified by software in
terms in 2-bit units.
If INPUT mode is canceled by software, this pin is placed
in OFF mode and enters the high-impedance state.
4
S1/LED
Refers to the I/O port.
In INPUT mode (S1), this pin can also be used as a key
return input from key matrix.
The availability of the pull-down resistor of the S0 and S1
ports can be specified by software in 2-bit units.
In OUTPUT mode (LED), this pin becomes the remote
control transmission display output (active low). When
the remote control carrier is output from the REM output,
this pin outputs the low level from the LED output
synchronously with the REM signal.
5
REM
Refers to the infrared remote control transmission output.
The output is active high.
Carrier frequency: fX/8, fX/64, fX/96, high-level,
fX/16, fX/128, fX/192 (usableonsoftware)

7 XOUT
8 XIN
9 GND
10 S2
Refers to the power supply.
These pins are connected to system clock ceramic
resonators.
Refers to the ground.
Refers to the input port.
The use of the STOP mode release of the S2 port can be
specified by software. When using this pin as a key input
from a key matrix, enable the use of the STOP mode
release (at this time, a pull-down resistor is connected
internally.)
When the STOP mode release is disabled, this pin can
be used as the input port which does not release the
STOP mode even if the release condition is established
(at this time, a pull-down resistor is not connected internally.)
11-14
KI0-KI3Note 2 These pins refer to the 4-bit input ports.
They can be used as a key return input from key matrix.
The use of the pull-down resistor can be specified by
software in 4-bit units.

Notes 1. Note that the drive capability of the low-level output side is held low.
2. In order to prevent malfunction, be sure to input a low level to more than one of pins KI0 to KI3 when
POC is released due to supply voltage startup.
