Nor Flash Forum Discussions

Regarding S25FL128SAGBHIA00,

If I/O voltage is 3.3V, which is good for VIO/RFU ?
1. "no connect".
2. connect to 3.3V.

Hi Everyone,

We are using parallel NOR flash(S29JL032J) in our custom board. I have gone through the datasheet of this chip. Need to develop driver for this chip. Any example programs on this will be greatly helpful. Tried searching the web, but no luck.

Any references?

ThankYou!!

S29GL128P11TFI020 is discontinued (PDN PD_075_24 - see attached, page 6) and the replacement recommended on the same PDN is S29GL128S90TFI020. However, S29GL128P11TFI020 can work in either byte or word mode, and I don't see that capability with the recommended replacement part S29GL128S90TFI020. Of course, my legacy design uses the byte mode of operation. How can Infineon recommend a non 100% compatible replacement!? Can anyone confirm this, or am I missing something? Perhaps it is because this was originally a Cypress part. 

Hi,

I am after access to the Cypress Cypress FFS package  for the S29GL128S10TFI020.

Thanks.

I'm currently reviewing the S25FL512S to be used as a QSPI device. Looking through the data sheet I can see a rise and fall time slew rate specified for the clock. Are there any rise and fall time specifications for any of the data lines or the chip select line?  Under the AC test measurement conditions I can see a maximum Input Rise and Fall time of 2.4 ns listed, but that's about all I can find.

Hello, 

We are developing battery operated device with u-blox NORA-B106-10B (ESP32-S3) module as a MCU. Due to large flash (64 Mbit) project requirement, we have selected Infenion S25FL064L (S25FL064LABMFI013) flash connected over SPI interface. 

As per ESP-IDF docuement, (esp_deep_sleep_start()) function will force power down flash regardless of user configuration. 

As per our testing observation with ESP32-S3-WROOM-1 (It has external 64Mbit SPI flash memory. Sorry, Not sure about Flash memory vendor part number), we could put SPI flash memory in sleep mode and takes less than 1 mA.

Same test we have also performed with u-blox NORA-B106-10B  and Infenion S25FL064L (S25FL064LABMFI013) flash memory in our prototype hardware. It takes around 10-12 mA current consumption when MCU in sleep mode (lowest power mode of ESP32-S3). It means, S25FL064L couldn't switch to power down mode when MCU in sleep mode.

Looking forward for your response. Thanks in advance.

Hi,

Is this part (S34ML02G200BHI003) in Production/NRND/EOL?
