(1) Serial interface UART0
Serial interface UART0 has two modes: asynchronous serial interface (UART) mode and infrared data transfer
mode.
•
Asynchronous serial interface (UART) mode
This mode enables full-duplex operation wherein one byte of data starting from the start bit is transmitted
and received.
The on-chip UART-dedicated baud-rate generator enables communication using a wide range of selectable
baud rates. In addition, a baud rate can be also defined by dividing the clock input to the ASCK0 pin.
The UART-dedicated baud-rate generator can also be used to generate a MIDI-standard baud rate (31.25
kbps).
•
Infrared data transfer mode
This mode enables pulse output and pulse reception in data format.
This mode can be used for office equipment applications such as personal computers.

(2) Serial interface 3nNote
Serial interface 3n has one mode: 3-wire serial I/O mode.
•
3-wire serial I/O mode (fixed as MSB first)
This is an 8-bit data transfer mode using three lines: a serial clock line (SCK3n), serial output line (SO3n),
and serial input line (SI3n).
Since simultaneous transmit and receive operations are enabled in the 3-wire serial I/O mode, the
processing time for data transfer is reduced.
The first bit in 8-bit data in the serial transfer is fixed as MSB.
The 3-wire serial I/O mode is useful for connection to a peripheral I/O devices, and display controllers, etc.,
that include a clocked serial interface.

(3) Serial interface IIC0 (µPD780024AY Subseries only)
Serial interface IIC0 has one mode: I2C (Inter IC) bus mode (supporting multimaster).
•
I2C bus mode (supporting multimaster)
This is an 8-bit data transfer mode using two lines: a serial clock line (SCL0) and a serial data bus line
(SDA0).
This mode complies with the I2C bus format, and can output a “start condition”, “data”, and a “stop condition”
during transmission via the serial data bus. This data is automatically detected by hardware during
reception.
Since SCL0 and SDA0 are open-drain outputs in IIC0, pull-up resistors for the serial clock line and the serial
data bus line are required.

7. EXTERNAL DEVICE EXPANSION FUNCTION
The external device expansion function is for connecting external devices to areas other than the internal ROM,
RAM, and SFR. Ports 4 to 6 are used for external device connection.
8. STANDBY FUNCTION
The following two standby modes are available for further reduction of system current consumption.
•
•
HALT mode: In this mode, the CPU operation clock is stopped. The average current consumption can be
reduced by intermittent operation by combining this mode with the normal operation mode.
STOP mode: In this mode, oscillation of the main system clock is stopped. All the operations performed on
the main system clock are suspended, and only the subsystem clock is used, resulting in
extremely small power consumption. This can be used only when the main system clock is
operating (the subsystem clock oscillation cannot be stopped).

Note The current consumption can be reduced by stopping the main system clock. When the CPU is operating
on the subsystem clock, set bit 7 (MCC) of the processor clock control register (PCC). The STOP instruction
cannot be used.
Caution When the main system clock is stopped and the device is operating on the subsystem clock, wait
until the oscillation stabilization time has been secured by the program before switching back to
the main system clock.
9. RESET FUNCTION
The following two reset methods are available.

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 conditions that
ensure that the absolute maximum ratings are not exceeded.

Notes 1. Indicates only oscillator characteristics. Refer to AC Characteristics for instruction execution time.
2. Time required to stabilize oscillation after reset or STOP mode release.
Cautions 1. When using the main system clock oscillator, wire as follows in the area enclosed by the broken
lines in the above figures to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating current flows.
• Always make the ground point of the oscillator capacitor the same potential as VSS1.
• Do not ground the capacitor to a ground pattern through which a high current flows.
• Do not fetch signals from the oscillator.
2. When the main system clock is stopped and the system is operating on the subsystem clock,
wait until the oscillation stabilization time has been secured by the program before switching
back to the main system clock.

Notes 1. Indicates only oscillator characteristics. Refer to AC Characteristics for instruction execution time.
2. Time required to stabilize oscillation after VDD reaches oscillation voltage range MIN.
Cautions 1. When using the subsystem clock oscillator, wire as follows in the area enclosed by the broken
lines in the above figures to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating current flows.
• Always make the ground point of the oscillator capacitor the same potential as VSS1.
• Do not ground the capacitor to a ground pattern through which a high current flows.
• Do not fetch signals from the oscillator.
2. The subsystem clock oscillator is designed as a low-amplitude circuit for reducing current
consumption, and is more prone to malfunction due to noise than the main system clock
oscillator. Particular care is therefore required with the wiring method when the subsystem
clock is used.

Notes 1. Value when the external clock is used. When a crystal resonator is used, it is 114 µs (MIN.).
2. Selection of fsam = fX, fX/4, fX/64 is possible using bits 0 and 1 (PRM00, PRM01) of prescaler mode register
0 (PRM0). However, if the TI00 valid edge is selected as the count clock, the value becomes fsam = fX/8.

Notes 1. In the start condition, the first clock pulse is generated after this hold time.
2. To fill in the undefined area of the SCL0 falling edge, it is necessary for the device to internally provide
at least 300 ns of hold time for the SDA0 signal (which is VIHmin. of the SCL0 signal).
3. If the device does not extend the SCL0 signal low hold time (tLOW), only the maximum data hold time
tHD:DAT needs to be fulfilled.
4. The high-speed mode I2C bus is available in a standard mode I2C bus system. At this time, the conditions
described below must be satisfied.
• If the device does not extend the SCL0 signal low state hold time
tSU:DAT ≥ 250 ns
• If the device extends the SCL0 signal low state hold time
Be sure to transmit the next data bit to the SDA0 line before the SCL0 line is released (tRmax. + tSU:DAT
= 1000 + 250 = 1250 ns by standard mode I2C bus specification).
5. Cb: Total capacitance per bus line (unit: pF)

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 VDD 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.
Note: Purchase of NEC I2C components conveys a license under the Philips I2C Patent Rights to use these
components in an I2C system, provided that the system conforms to the I2C Standard Specification as
defined by Philips.

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, software and information in the design of customer's equipment shall be done under the full
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third
parties arising from the use of these circuits, software and information.
While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as
redundancy, fire-containment, and anti-failure features.
NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor product 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 and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
NEC (as defined above).
