Hello,

Could you tell the specification of the Chip Erase Time (typ/max) in S29GL128S?

I found it out for S29GL064S in the datasheet,  but the S29GL128S datasheet doesn't have.

MPN  S29GL128S90TFI010

Best Regards,

Naoaki Morimoto

Hi,

For S29GL128S, typical chip erase will be 275ms/sector * 128sectors = 35200ms.

Max chip erase will be 1100ms/sector * 128sectors = 140800ms

Thanks,

Nada

S29GL128S90FHI010 不能擦除,可以缓冲编程全0,读出来全0。但是不能擦除,给的擦除命令之后,状态寄存器0X00并且RY引脚为低,经过几百微妙状态寄存器为0X80并且RY引脚变高,感觉是执行了擦除命令而未改变阵列数据。命令参照datesheet中命令页的表格执行。还有S29GL256S、S29GL512S、S29GL01GS都遇到这个难题。你们那边可以帮忙分析分析给个建议吗?很着急。
