I inquire about the specification of SPI Flash Memory of CYW20706.

The three recommend memories below have a 1.65V to 3.6V full voltage range.

Adesto : AT25XE041B

Gigadevice : GD25WD40C

Macronix : MX25R4035F

The voltage applied to CYW20706 is 3.3V.

Can I use a memory with a full voltage range of 2.7V to 3.6V?

ex. GD25Q40C (attachment)

If not, why?

Thanks & Regards,

Park Jung Hoon

Hi Park Jung Hoon,

The SPI flash used in CYW2070xV3 eval boards is MX25R4035FZUIL0- MX25R4035FZUIL0 Macronix | Integrated Circuits (ICs) | DigiKey which has operation voltage 1.65V - 3.6V.

Therefore, you should be able to use the GD25Q40C as you mentioned in your query. However, I am not sure if we have tested this memory with our chip.
