An integral part of the Renesas product portfolio is the custom masked MCU, which allows a customer to embed code into the device ROM at the time of manufacture.
This site provides the latest ROM-ordering information for MCUs.
In the ROM programming confirmation forms and mask confirmation forms, please read "floppy disk" and "floppy disk must be 3.5-inch 2HD type and DOS/V format" as "CD-R".
We accept data on CD-R. Also, we have stopped accepting orders by EPROM.
Please submit mask files on CD-R.
For other methods of ROM transfer, please contact the sales office which supports your region.
