WRR commandは,datasheet中の11.3.4 (page82)からStatus Reg1と、Config Reg1向けの書き込みコマンドのようですが、

Fig 57 (page 82) とFig 58 (page83)のWrite Register Command Sequenceでは、Config2および3へのアクセスが表示されています。

（S25F064S Datasheet (002-03631 Rev.G)  より）

Fig57, Fig58は誤記という認識ですが、正しいでしょうか？また、同figは、WRAR(71h) のCommand Sequenceでしょうか？

よろしくお願い致します。

Hi all,

Customer asks that which is Assembly site  of S29GL256P90TFCR10A.

They understood this parts is EOLed already.

Capacitance for CE# isn't specified in the S29GL512T datasheet, but it is specified in the older S29GL512P datasheet. Is there any information available on the capacitance of CE# on the S29GL512T TSOP package version?

The label on the surface of chip S29GL512N10FAI010 is GL512N10FAI01 0911VVF JJ  @04 SPANSION. What does the numbers and letters of 0911VVF JJ  @04 SPANSION meaning? Thanks

Hello,

I use a S25FL256S flash memory and I noticed that no P_ERR bit if

I write to an unerased (not all bits are ones) memory area, however

the writing fails. Is this normal behavior or does I overlook something?

I hoped I can detect similar errors via P_ERR. Should I reread the data

after writing operation if I would like to check the result of operation?

Thanks.

I use S29GL01GT NOR Flash with ST ARM Cortex M7 STM32F767 Controller.

When I use "Write to Buffer" Command Set  the "Program Buffer to Flash" command sometimes is not sent.

In this case I tried to reset the Flash but it is stopped to work. The Flash enters to any mode and neither  command as "Read"  or  "Erase" does not work.

I used:

Reset/ASO Exit

Write-to-Buffer-Abort Reset

Status Register Clear

When I send all of commands from the "Write to Buffer" Set everything works perfect

Please advice me any sequence of command to reset the component !
