LC87F40C8A
Method of how to rewrite it in FLASH programmer/
SANYO FLASH writing tool (SFWS)
When reading or writing data to the LC87F40C8A, FLASH programmer of our recommendation or SANYO FLASH
writing tool (SFWS) is used. In both cases, exclusive conversion board (W87F40C8D, W87F40C8Q) is needed.

(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
• W87F40C8D: DIP64S purpose
• W87F40C8Q: QIP64E purpose
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.
W87F40C8D: when viewing from the edge closest to jumper SW, pin 1 is located on the lower right of both the chip
and conversion board.
W87F40C8Q: when viewing from the edge closest to jumper SW, pin 1 of the chip is located on the upper right while
pin 1 of the conversion board is located on the lower right.
