DESCRIPTION  
The µPD780021A(A), 780022A(A), 780023A(A), 780024A(A), 780021AY(A), 780022AY(A), 780023AY(A) and  
780024AY(A) are products to which a quality assurance program more stringent than that used for the µPD780021A,  
780022A, 780023A, 780024A, 780021AY, 780022AY, 780023AY and 780024AY (standard models) is applied (NEC  
classifies these products as “special” quality grade models).  
The µPD780021A(A), 780022A(A), 780023A(A), and 780024A(A) are members of the µPD780024A Subseries of  
the 78K/0 Series. Only selected functions of the existing µPD78054 Subseries are provided, and the serial interface  
is enhanced.  
The µPD780021AY(A), 780022AY(A), 780023AY(A), and 780024AY(A) are the µPD780024A Subseries with a  
multimaster supporting I2C bus interface, which makes them suitable for AV equipment.  
Flash memory versions, the µPD78F0034A and 78F0034AY, that can operate in the same power supply voltage  
range as the mask ROM versions, and various development tools, are also available.  
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before  
designing.

(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 also be 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 3n  
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 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 areas. 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.  
External reset by RESET signal input

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. 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).

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 l2C 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.
