S29GL064S70 Reset# pin connection

[Anilsp31]

Hello,

I have a query regarding S29GL064S70 Flash.

Is the RESET# pin need to be driven low after Power up of the board containing this flash?

Does it need to be pulsed low, before the flash can be used for other operations?

Or can we pull-up the RESET# pin permanently to VCC?

Let me know answers to above queries.

Thanks and Regards,

Anil Patil

Hi Anil,

When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, output pins go to High-Z, and all read / write commands are ignored for the duration of the RESET# pulse. Program / Erase operations that were interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity.

The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the flash memory, enabling the system to read the boot-up firmware from the flash memory. If you pull RESET# pin high constantly with VCC, it would not be possible to reset the flash without turning the power supply off.

Thanks,
Ronak
