when
POC is released due to supply voltage startup.
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.
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 S
0
and S
1
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.
Refers to the I/O port.
In INPUT mode (S
1
), this pin can also be used as a key
return input from key matrix.
The availability of the pull-down resistor of the S
0
and S
1
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.
Refers to the infrared remote control transmission output.
The output is active high.

The use of the STOP mode release of the S

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.)
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.

2. DIFFERENCES AMONG
PD64A, 65, AND
PD6P5
Table 2-1 shows the differences among the
PD64A, 65, and
PD6P5.
The only differences among these models are the program memory, supply voltage, system clock frequency,
and oscillation stabilization wait time, and the CPU function and internal peripheral hardware are the same.
The electrical characteristics also differ slightly. For the electrical characteristics, refer to the Data Sheet of each
model.

10 bits
This one-time PROM is configured with 10 bits per step and is addressed by the program counter.
The program memory stores programs and table data.
The 22 steps from addresses 7EAH through 7FFH constitute a test program area and must not be used.

3. WRITING AND VERIFYING ONE-TIME PROM (PROGRAM MEMORY)
The program memory of the
PD6P5 is a one-time PROM of 2,026
10 bits.
To write or verify this program memory, the pins shown in Table 3-1 are used. Note that no address input pin
is used. Instead, the address is updated by using the clock input from the CLK pin.

3.1 Operation Mode When Writing/Verifying Program Memory
The
PD6P5 is set in the program memory write/verify mode when +6 V is applied to the V

pin and +12.5 V
is applied to the V

pin after the
PD6P5 has been in the reset status (V
DD
= 5 V, V
PP
= 0 V) for a specific time.
In this mode, the operation modes shown in Table 3-2 can be set by setting the MD

pins. Connect
all the pins other than those shown in Table 3-1 to GND via pull-down resistor.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for
any parameter. That is, the absolute maximum ratings are rated values at which the product
is on the verge of suffering physical damage, and therefore the product must be used under

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static
electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental
control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid
using insulators that easily build static electricity. Semiconductor devices must be stored and
transported in an anti-static container, static shielding bag or conductive material. All test and
measurement tools including work bench and floor should be grounded. The operator should be
grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar
precautions need to be taken for PW boards with semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input
levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each
unused pin should be connected to V
DD
or GND with a resistor, if it is considered to have a
possibility of being an output pin. All handling related to the unused pins must be judged device
by device and related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until
the reset signal is received. Reset operation must be executed immediately after power-on for
devices having reset function.

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual
property rights of third parties by or arising from use of a device described herein or any other liability arising
from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights

Descriptions of circuits, software, and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these circuits,

of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third

While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special:
Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific:
Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
