2. Introduction
The PCA7438F-64A and PCA7438H-64A are PROM programming adapters for 8-bit 38000 Series
38C1 Group MCUs. These adapters are tools that can be used to write a program into internal PROM
of MCUs using a commercially available PROM programmer.
This manual describes the specifications and the operation of PCA7438F-64A/PCA7438H-64A.
Figure 2.1 shows the external view and the constituent parts of them.

4. How to Write the Program
This chapter describes how to write programs using a PROM programmer. For details on how to
operate the PROM programmer, refer to the user's manual of the PROM programmer.
4.1 Programming Procedures
Follow procedures (1) to (7) to write programs into the MCU.
(1) Read the program into the PROM programmer.
(2) Attach the adapter to the PROM programmer. (See Section 4.2)
(3) Insert the MCU into the adapter. (See Section 4.3)
(4) Specify the programming area of the MCU using the PROM programmer. (See Section 4.5) *1
(5) Using the PROM programmer's erase check function, check whether data can be written into
the programming area of the MCU. *2
(6) Write the program into the programming area of the MCU using the PROM programmer. *2
(7) Verify the programming area of the MCU using the PROM programmer to check whether the
program is written into the MCU correctly. *2
1
*
*
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 etc. may not also be performed
completely.
2
Some PROM programmers perform the steps (5) through (7) automatically.
( 8 / 16 )
4.2 Attaching the Adapter to a PROM Programmer
As shown in Figure 4.1, attach the pin No. 1 of the PCA7402E PROM programmer 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.
Figure 4.1 Attaching the adapter to the PROM programmer
4.3 Inserting an MCU into the Programming Adapter
As shown in Figure 4.2, insert the MCU into the IC socket, with the pin No. 1 of the MCU matched
to the pin No. 1 of the IC socket on the PCA7438F-64A/PCA7438H-64A.
Be careful when inserting the MCU because incorrect insertion can cause fatal
damage to the MCU.

4.4 Precautions When Handling the Adapter
Do not touch the connector in the IC socket and the pins on the PROM programmer connector,
otherwise it 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.
4.5 Setting a Programming Area
When writing the program into the MCU, be sure to set the programming area. And also, specify its
device of the PROM programmer.

5. Recommended PROM Programmers
The PROM programmers listed in Table 5.1 are recommended for this product. 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.

7.2 MCU Does 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) Is the offset address specified correctly when copying data into the PROM programmer?
(2) 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.
(3) 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.
7.3 Other Precautions
7.3.1 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 "5. Recommended PROM Programmers". 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.
7.3.2 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.

*
Depending on PROM programmer manufacturers, this may be referred to by another name (e.g.
ID code).
