Method of how to rewrite it in FLASH programmer / SANYO FLASH writing tool (SFWS)
When reading or writing data to the LC86F3448B , FLASH programmer of our recommendation or SANYO FLASH
writing tool (SFWS) is used. In both cases, exclusive conversion board (W86F3448D, W86F3448M) is needed.

The LC86F3448B does not support a silicon signature feature.
Do not use the feature (automatic device type selection) when programming this device.
To avoid erasing the program, confirm the setting of the protection for activating the written program before using.
It can’t be written with device code 29EE512
(2) SANYO FLASH writing tool (SFWS)
PC is connected with writer unit (SKK) by USB cable and it uses it.
(3) Exclusive writing conversion board
• W86F3448D • • • DIP36S purpose (It is common with production discontinuance model
(LC86F3448A / LC86F3548A) )
• W86F3448M • • • MFP36SDJ purpose (It is common with production discontinuance model
(LC86F3448A/ LC86F3548A) )
When using the conversion board, all of the jumper SW must be set to the OFF position.
If set to the ON position, read/write operations will not perform correctly.
Pin 1 of the conversion board should be located as indicated below.
