We are giving Vid= 12V on reset pin of S29JL032J to make it unprotected mode for programming.

Did Vid=12V really required for programming or can I keep always 3.3V

Hello Gursewak,

The WP# function is enabled at VIL and the ACC operation is enabled at 12.0V(min)

Connecting the WP#/ACC pin to VID = 12.0V enables the Accelerated Program Operation.

(WP# function remains disabled @ 12.0V)

Therefore, please connect the WP#/ACC pin to ~3.3V, which the Write Protect (WP#) still

remains disabled, as well as the Accelerated Program Operation (ACC) which is also disabled.

Hope this helps...

Best regards,

Albert

Thanks Albert for your response.

We are giving Vid=12V to the Reset# Pin of the S29JL032J during Programming to make it unprotected mode first as mentioned in the datasheet. We have below two queries.

1. Is really Vid=12V required on Reset# for Programming
