Octal xSPI Memory

Blazingly Fast. Low Power Consumption

  • High Bandwidth
  • Low Power
  • Execute-in-place
  • Read While Write
  • Security

With the need for greater processing performance at lower power, execute-in-place (XiP) is quickly becoming the architecture of choice for IoT devices. EcoXiP’s blazingly fast performance and low power consumption allow even time-critical software to be executed directly out of non-volatile memory, reducing boot time and system cost.

Best performance, best power

Performance
CoreMark® test on NXP’s i.MX RT1050 with 8 instruction cache
invalidations every ms to simulate task switching & interrupt handling.

Efficiency
CoreMark® score / power consumption.

AT25XE321D

Hi,

I'm using AT25XE321D serial flash IC in one of the project I'm working on. I've gone through the datasheet of this and was trying to program it using SPI mode. But I found that even at the first step while trying to read the JEDEC ID, it reads the id as 0 (5 Bytes). I proceeded and tried to read status registers and there also I got 0 value. Thinking that it is the default values I tried to do the "write enable" by writing to status register 1 (set bit 1). Even after this when I tried to read the status register 1 value, I get 0 itself.  

Is there something I'm missing? Is there any document which can guide me through the correct way of doing this?

Hello grai2907,

Reading the JEDEC ID and status reg is just as it is for all other xx25yyy Flash memory parts so something else is going wrong. 

Have you tried multiple devices? Which uController are you using? Are you using single SPI bus (not QSPI) Can you share the relevant part of the schematic? Can you provide some 'scope captures of the signal and power lines? What SPI clock speed are you using, what voltage are you running the system at? Are there any other devices on the SPI Bus or is there anything else that could be holding the MISO low? Does the MISO line ever go high?

If you would prefer to discuss this out with the forum, please send the info to gordon.macnee.wj@renesas.com
