µPD78P083
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD78P083 is a member of the µPD78083 subseries of the 78K/0 series products. It includes an on-chip, 24-Kbyte,
one-time PROM or EPROM.
Because this device can be programmed by users, it is ideally suited for applications involving the evaluation of systems
in development stages, small-scale production of many different products, and rapid development and time-to-market of
a new product.
Caution
The µPD78P083DU does not maintain planned reliability when used in your systems’ mass-produced
products. Please use only experimentally or for evaluation purposes during trial manufacture.
The details of functions are described in the user’s manuals. Be sure to read the following manuals before
designing.

FEATURES
• Pin-compatible with mask ROM version (except VPP pin)
• Internal PROM: 24 Kbytes Note
• µPD78P083DU: Reprogrammable (ideally suited for system evaluation)
• µPD78P083CU, µPD78P083GB: One-time programmable (ideally suited for small-scale production)
• Internal high-speed RAM: 512 bytes Note
• Can be operated in the same supply voltage as the mask ROM version (VDD = 1.8 to 5.5 V)
• Corresponding to QTOPTM Microcontrollers
Note The internal PROM and internal high-speed RAM capacities can be changed by setting the internal memory size
switching register (IMS).
Remark
QTOP microcontroller is a general term for microcontrollers which incorporate one-time PROM and are totally
supported by NEC's programming service (from programming to marking, screening and verification).
*
Differs from the mask ROM version in the following points
The same memory mapping as the mask ROM version is enabled by setting the internal memory size switching
register (IMS).
In this document, the term PROM is used in parts common to one-time PROM versions and EPROM versions.
The information in this document is subject to change without notice.

µPD78P083
1. DIFFERENCES BETWEEN THE µPD78P083 AND MASK ROM VERSIONS
The µPD78P083 is a single-chip microcontroller with an on-chip one-time PROM or with an on-chip EPROM which has
program write, erasure and rewrite capability.
Setting the internal memory size switching register (IMS) makes the functions except the PROM specification identical
to the mask ROM versions, that is, the µPD78081 and µPD78082.
Differences between the µPD78P083 and mask ROM versions are shown in Table 1-1.

3. INTERNAL MEMORY SIZE SWITCHING REGISTER (IMS)
This is a register to disable use of part of internal memories by software. By setting this internal memory size switching
register (IMS), it is possible to get the same memory mapping as that of the mask ROM versions with a different internal
memory (ROM, RAM).
IMS is set with an 8-bit memory manipulation instruction.
RESET input sets IMS to 46H.

4. PROM PROGRAMMING
The µPD78P083 has an internal 24-Kbyte PROM as a program memory. For programming, set the PROM programming
mode with the VPP and RESET pins. For the connection of unused pins, refer to “PIN CONFIGURATIONS (TOP VIEW)
(2) PROM programming mode.”
Caution
Programs must be written in addresses 0000H to 5FFFH (The last address 5FFFH must be specified).
They cannot be written by a PROM programmer which cannot specify the write address.
4.1 Operating Modes
When +5 V or +12.5 V is applied to the VPP pin and a low-level signal is applied to the RESET pin, the PROM programming
mode is set. This mode will become the operating mode as shown in Table 4-1 when the CE, OE, and PGM pins are set
as shown.
Further, when the read mode is set, it is possible to read the contents of the PROM.

µPD78P083
(1) Read mode
Read mode is set if CE = L, OE = L is set.
(2) Output disable mode
Data output becomes high-impedance, and is in the output disable mode, if OE = H is set.
Therefore, it allows data to be read from any device by controlling the OE pin, if multiple µPD78P083s are connected
to the data bus.
(3) Standby mode
Standby mode is set if CE = H is set.
In this mode, data outputs become high-impedance irrespective of the OE status.
(4) Page data latch mode
Page data latch mode is set if CE = H, PGM = H, OE = L are set at the beginning of page write mode.
In this mode, 1 page 4-byte data is latched in an internal address/data latch circuit.
(5) Page write mode
After 1 page 4 bytes of addresses and data are latched in the page data latch mode, a page write is executed by applying
a 0.1-ms program pulse (active low) to the PGM pin with CE = H, OE = H. Then, program verification can be performed,
if CE = L, OE = L are set.
If programming is not performed by a one-time program pulse, X times (X ≤ 10) write and verification operations should
be executed repeatedly.
(6) Byte write mode
Byte write is executed when a 0.1-ms program pulse (active low) is applied to the PGM pin with CE = L, OE = H. Then,
program verification can be performed if OE = L is set.
If programming is not performed by a one-time program pulse, X times (X ≤ 10) write and verification operations should
be executed repeatedly.
(7) Program verify mode
Program verify mode is set if CE = L, PGM = H, OE = L are set.
In this mode, check if a write operation is performed correctly after the write.
(8) Program inhibit mode
Program inhibit mode is used when the OE pin, VPP pin, and D0-D7 pins of multiple µPD78P083s are connected in
parallel and a write is performed to one of those devices.
When a write operation is performed, the page write mode or byte write mode described above is used. At this time,
a write is not performed to a device which has the PGM pin driven high.

VDD should be applied before VPP and removed after VPP.
VPP must not exceed +13.5 V including overshoot.
Reliability may be adversely affected if removal/reinsertion is performed while +12.5 V is being
applied to VPP.

4.3 PROM Read Procedure
The contents of PROM are readable to the external data bus (D0-D7) according to the read procedure shown below.
(1) Fix the RESET pin at low level, supply +5 V to the VPP pin, and connect all other unused pins as shown in “PIN
CONFIGURATIONS (TOP VIEW) (2) PROM programming mode”.
(2) Supply +5 V to the VDD and VPP pins.
(3) Input address of read data into the A0-A16 pins.
(4) Read mode
(5) Output data to D0-D7 pins.
The timings of the above steps (2) to (5) are shown in Figure 4-5.

5. PROGRAM ERASURE (µPD78P083DU ONLY)
The µPD78P083DU is capable of erasing (FFH) the data written in a program memory and rewriting.
To erase the programmed data, expose the erasure window to light having a wavelength shorter than about 400 nm.
Normally, irradiate ultraviolet rays of 254-nm wavelength. The amount of exposure required to completely erase the
programmed data is as follows:
• UV intensity x erasing time
: 30 W•s/cm2 or more
• Erasure time: 40 min. or more (When a UV lamp of 12,000 µW/cm2 is used. However, a longer time may be needed
because of deterioration in performance of the UV lamp, soiled erasure window, etc.)
When erasing the contents of data, set up the UV lamp within 2.5 cm from the erasure window. Further, if a filter is provided
for a UV lamp, irradiate the ultraviolet rays after removing the filter.
6. OPAQUE FILM ON ERASURE WINDOW (µPD78P083DU ONLY)
To protect from unintentional erasure by rays other than that of the lamp for erasing EPROM contents, or to protect internal
circuit other than EPROM from misoperating by rays, cover the erasure window with an opaque film when EPROM contents
erasure is not performed.
7. ONE-TIME PROM VERSION SCREENING
The one-time PROM version (µPD78P083CU, 78P083GB-3B4, 78P083GB-3BS-MTX) cannot be tested completely by
NEC before it is shipped, because of its structure. It is recommended to perform screening to verify PROM after writing
necessary data and performing high-temperature storage under the condition below.
*

NEC offers for an additional fee one-time PROM writing to marking, screening, and verify for products designated as
"QTOP Microcontroller". Please contact an NEC sales representative for details.

Caution When using the oscillation circuit of the main system clock, wire the portion enclosed in broken lines
in the figures as follows to avoid adverse influences on the wiring capacitance:
• Keep the wiring length as short as possible.
• Do not cross the wiring over other signal lines.
• Do not route the wiring in the vicinity of lines through which a high fluctuating current flows.
• Always keep the ground point of the capacitor of the oscillation circuit at the same potential as VSS.
• Do not connect the power source pattern through which a high current flows.
• Do not extract signals from the oscillation circuit.

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.

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, customer 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: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices in “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 NEC Sales Representative in advance.
Anti-radioactive design is not implemented in this product.
