For some reason, I can not program my Renesas MCU. What are the possible problems?

The most frequent problems we have found in our support experience are as follows.

Wrong Set-up --> Please review the installation manual carefully.

(1) Reconfirm that the switches are correctly set for your MCU.

(2) Reconfirm that your ROM programmer is installed with the accessory socket board which corresponds to our

programming adapter.

(3) Reconfirm that the programming block is properly mapped.

(4) Reconfirm that your selected device mode is correct.

Bad contact due to non-conductive incrustation

(1) Programming adapter pin head incrustation

Greasy or rusty build-up on pin heads where contact is made to the ROM programmer often causes a bad connection.

Clean adapter pin heads with an appropriate cleanser.

(2) Junction incrustation or abrasion of ROM programmer socket

Older ROM programmers often have a bad socket junction due to worn metal, distortion, or non-conductive

incrustation. Many ROM programmers have a feature that allow you to replace the socket. We recommend replacing

the socket of your ROM programmer if you haven't done so yet.

(Note) The pin heads on our ROM programmer do not have the exact same shape as the EPROM chips. Although your

ROM programmer may not accept our adapter, it will accept an EPROM due to this form factor difference.

(3) Junction abrasion in programming adapter socket

Our programming adapter is intended for software development but not for production programming. Therefore, the

expected duration cycle of the adapter socket is around 5000 times. When you use the adapter for repetitive

programming close to the socket duration time, the adapter may develop abrasions, etc. We recommend using a new

adapter when you encounter this type of problem.

ROM programmer compatibility problem

(1) Use of non-recommended ROM Programmer

Our PROM MCUs do not have exactly the same characteristics as other EPROM chips. Therefore, some ROM

programmers do not have the compatibility for programming our MCUs. Please use EPROM programmers which we

have qualified. These recommended ROM programmers are listed in both the Programming Adapter Manual and

EPROM MCU data sheets.

(2) ROM programmer device identification code function

Please do not use the device ID* function included in your EPROM programmer. This function might damage the

MCU and the Programming Adapter. The device ID usually indicates the device characteristics and manufacturer and,

therefore, will not match our MCU.

* The nomenclature for "device ID" varies according to ROM programmer manufacturer: ID code, etc.
