CC3235MODASF: 32MBit Serial Flash Programming - CC3235MODASF

Part Number: CC3235MODASF
Other Parts Discussed in Thread: BEEPROG2

Tool/software:

Hi,

In CC3235MOD block, we found that it has 32MBit Serial flash, We need few queries regarding how to utilize this.

 1) Can we use SSPI(of CC3235) to communicate with the 32Mbit Serial flash for data storage?

 2) What tool/device should we use to program the Serial flash memory by external programming? Also, Please suggest any programmer  and tool as well

    Hi,

    1) No, you cannot use SSPI for communication with SPI flash from your code. SSPI is used by NWP (internal WiFi coprocessor) for communication with sFlash (4MB SPI FLASH integrated inside module). If you want to store own data into sFlash, you can use sl_ filesystem API. Other way can be connect additional SPI flash to GSPI. At this case will be management up to you.

    2) sFlash can be programmed in production by any SPI production programmer with capability of program MX25R3235F. Like a Total Phase Cheatech, Elnec Beeprog2...

    Additional details you can see at production line guide.

    Hi Jan,

    Are you referring this flash memory cannot be used for normal flash storage? like in microcontroller we can use external flash to store images and some other data and we can easily access that memory while normal working condition. Kindly clarify whether this memory used like this or not?

    Thanks

    Hi Lakshmi,

    You cannot access to sFlash directly from MCU. Access can be done via sl_ filesystem API only. You can use this memory for storing user data, which not change often, because number of write cycles is limited and there is not supported wear levelling. This memory is not suitable for data-logging purpose.

    Additional details you can find here.
