Chapter 2. Introduction
The PCA7401 is a PROM programming adapter for Renesas 8-bit 7200 Series MCUs. The adapter
is a tool that can be used to write programs into an internal PROM of MCUs using a commercially
available PROM programmer.
This manual describes the specifications and the operation of the PCA7401.
Figure 2.1 shows the external view of the PCA7401 and its constituent parts.

Chapter 3. Usage
This chapter describes procedures you need to follow when writing the program.
For details on how to operate the PROM programmer, refer to the user's manual of the PROM
programmer.
3.1 Programming Procedure
Follow these procedures (1) through (7) to write the program into the MCU.
(1) Read the program into the PROM programmer.
(2) Attach the adapter to the IC socket of the PROM programmer (see section 3.2).
(3) Mount the MCU into the adapter (see section 3.3).
(4) Set the programming area with the PROM programmer (see section 3.4).
(5) Using the PROM programmer's erase check function, check whether data can be written into
the MCU's programming area.*
(6) Write the program into the programming area of the MCU using the PROM programmer.*
(7) Verify the programming area of the MCU using the PROM programmer to check whether the
program has been written into the MCU correctly.*
Notes
* Be sure to set the programming area. Otherwise the mode's shift to the programming mode may
not be performed successfully. The erase check function and others may not also be performed
completely.
* Some PROM programmers perform the steps (5) to (7) automatically.
( 7 / 18 )
3.2 Attaching the Adapter to a PROM Programmer
As shown in Figure 3.1, attach the pin No. 1 of the connector (standard-pitch 32-pin pin-header
mounted) to the pin No. 1 of the IC socket of the PROM programmer.
Be careful when attaching the adapter because incorrect insertion can cause fatal
damage to the MCU.

( 8 / 18 )
3.3 Mounting an MCU into the Adapter
As shown in Figure 3.2, insert the No. 1 pin of an MCU into the No. 1 pin of the IC socket.
Be careful when inserting the MCU because incorrect insertion can cause fatal
damage to the MCU.

CAUTION
Caution to Be Taken for Handling an MCU:
• Do not touch the connector in the IC socket and the pins on the PROM programmer
connector. Otherwise it can cause an electrical insulation failure because of dirt.
When not using, attach the connector pins of this product to the conductive sponge
as it was shipped from the factory.
( 9 / 18 )
3.4 Setting the Programming Areas
When writing the program into the MCU, be sure to set the programming area. And also, specify its
device of the PROM programmer.

3.5 Recommended PROM Programmers
The PROM programmers listed in Table 3.2 are recommended for the adapter PCA7401. Using the
actual products, we have verified that these PROM programmers can be used to write programs
without problem. Nonconformity occurring by using any other PROM programmers can not be
supported. For the latest type of PROM programmers, contact the manufacturer to confirm whether
it can be used for your product.

Contact failure
The PROM programmer connector at which the PROM
programmer is contacted may be stained. Clean it with
alcohol, etc.
5.2 MCUs Do Not Function Normally
The program operates normally on the emulator, but when the MCU that has normally been written
is attached the same program does not function normally.
(1) In the emulator, NOPs are often inserted in the area where the program has not been read, therefore
the program happens to appear functioning normally even though it may have gone wild. Check
your program again.
(2) The emulator and the actual MCU may differ in characteristics. Consult the user's manual of the
emulation pod to check for differences in characteristics again.
( 15 / 18 )
5.3 Other Precautions
(1) About the Recommended PROM Programmers
Not all PROM programmers available on the market can be checked to see if they function properly.
There are several PROM programmers that we have verified to function properly. These products are
listed as recommended PROM programmers in this user's manual. Other PROM programmers may
also be used providing that you verified them to function properly.
Note: No matter which type of PROM programmer you use, it is necessary to verify completion of
programming by executing screening, etc. that are stipulated for each MCU used.
(1) About Reading Out of Device Identification Code *1
Please do not use the PROM programmer's device identification code readout function.
Using this function may break down the MCU. The device identification code is included in EPROM
to indicate the manufacturer code and device code; it is not included in the MCU.
*1 Depending on PROM programmer manufacturers, this may be referred to by another name (e.g.
ID code).
