The µPD70F3102-33 is a product that substitutes the internal mask ROM of the µPD703102-33 with flash
memory. This enables users to perform on-board program writing and erasure, enabling effective evaluation during
system development, small-lot production of multiple devices, and rapid production start, and quick development and
time-to-market.
A version using a 3.3 V power supply for external pins, the µPD70F3102-A33, is also available.
For additional information, refer to the following user’s manuals. Be sure to read them before starting
design.
The information contained in this document is being issued in advance of the production cycle for the
device. The parameters for the device may change before final production or NEC Corporation, at its own
discretion, may withdraw the device prior to its production.
Not all devices/types available in every country. Please check with local NEC representative for
availability and additional information.

Cautions 1. There are differences in noise immunity and noise radiation between the flash memory
version and mask ROM version. When pre-producing an application set with the flash
memory version and then mass-producing it with the mask ROM version, be sure to conduct
sufficient evaluation for commercial samples (not engineering samples) of the mask ROM
version.
2. When switching from the flash memory version to the mask ROM version, write the same
code to the free area of the internal ROM.

3. FLASH MEMORY PROGRAMMING
The following two flash memory programming methods are available.
(1) On-board programming
The program is written to the flash memory using a dedicated flash programmer after the µPD70F3102-33 is
mounted on the target board. Install the connectors, etc., required for communication with the dedicated flash
programmer, on the target board.
(2) Off-board programming
The program is written to the flash memory using a dedicated adapter before the µPD70F3102-33 is mounted on
the target board.
3.1Selection of Communication System
Writing to the flash memory is done via serial communication using the dedicated flash programmer. Select one
of the communication modes listed in Table 3-1. Base your selection of the communication mode on the selection
format shown in Table 3-1. Refer to the number of VPP pulses shown in Table 3-1 when selecting the communication
mode.

3.2Flash Memory Programming Functions
Flash memory programming is performed by sending and receiving commands and data according to the selected
communication mode. Table 3-2 shows the main flash memory programming functions.

FunctionDescription
Batch erasureErases the contents of the entire memory.
Batch blank checkChecks whether the entire memory has been erased.
Data writeWrites data to flash mem ory based on the write start address and the number of bytes to be writ ten.
Batch verifyCompares the contents of the entire m em ory with the input data.
3.3Connecting the Dedicated Flash Programmer
The connection of the dedicated flash programmer to the µPD70F3102-33 differs depending on the
communication mode. Figures 3-2 and 3-3 show the various connection types.

Cautions 1. Do not directly connect output pins (or I/O pins) of IC products, and do not connect them
directly to VDD, VCC, or GND. However, open-drain pins and open-collector pins can be
directly connected to each other. Moreover, external circuits that implement a timing that
avoids conflict with the output of pins that go into high-impedance can be directly
connected.
2. 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.
The ratings and conditions indicated for DC characteristics and AC characteristics
represent the quality assurance range during normal operation.
