4. How to Write the Program
This chapter describes procedures you need to follow when writing a program. For details on how
to operate the PROM programmer, refer to the user's manual of the PROM programmer.
4.1 Programming Procedure
Follow procedures (1) to (8) to write a program.
(1) Read the program into the PROM programmer. (Offset at C000016 required)
(2) Attach the adapter to the PROM programmer. (see Section 4.2)
(3) Set the switches (JP1). (see Section 4.3)
(4) Insert the MCU into the adapter. (see Section 4.4)
(5) Set the programming area with the PROM programmer. (see Section 4.7) *1
(6) Check to erase the programming area. *2
Using the PROM programmer's erase check function, check whether data can be written into
the MCU's programming area.
(7) Write the program into the programming area of the MCU using the PROM programmer. *2
(8) Verify the programming area of the MCU using the PROM programmer to check whether the
program is written into the MCU correctly. *2
Notes:
*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 (6) to (8) automatically.

4.2 Attaching Adapter to PROM Programmer
As shown Figure 4.1, attach the pin No. 1 of the PCA7402E 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 adapter to PROM programmer
4.3 Setting Switches
The setting of JP1 switch is prepared for MCUs with their ROM area expanded in the future. Use this
setting for the current MCUs. Figure 4.2 shows the factory-setting of JP1 switch.
: Position of DIC connector
Figure 4.2 JP1 switch setting
Note:
(1) Be sure to set the switch properly. Otherwise wrong settings can cause fatal damage to the MCU.
(2) Figure 4.2 applies to both PCA7302E1F-80 and PCA7302E1L-80.

4.4 Inserting MCU into Adapter
As shown in Figure 4.3, 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 adapter.
Be careful when inserting the MCU because incorrect insertion can cause fatal
damage to the MCU.
Figure 4.3 Inserting the MCU
4.5 Precautions When Opening and Closing IC Socket
When opening and closing the IC socket to insert the MCU, hold the adapter horizontally. Otherwise
the inside of the IC socket may become damaged and cause an electrical insulation failure. Figure 4.4
shows opening and closing of the IC socket.

4.6 Precautions When Handling Adapter
Don't 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.
4.7 Setting 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.

MCU type name
Internal ROM area
of MCU

Example
M30240ECFP 128K byte M5M27C201 2000016 - 3FFFF16 E000016 - FFFFF16
M302XXEC
Note:
(1) Be sure to set the programming mode properly. Otherwise wrong settings can cause fatal damage
to the MCU.
(2) The programming method for the M5M27C201 mode is the byte-programming method.
5. Recommended PROM Programmers
PROM programmers listed in Table 5.1 are recommended for the adapter. 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.

Note:
(1) Be sure to set the programming mode properly. Otherwise wrong settings can cause fatal damage
to the MCU.
(2) The programming method for the M5M27C201 mode is the byte-programming method.
