Other Parts Discussed in Thread: , CC3235S, CC3235SF
Hi,
We are using SPI flash (MX25R3235F) with CC3220S MCU. Both MCU and SPI flash VCC voltage is 3V. The same SPI flash part no is used in launch pad of CC3220S.
We are seeing issue in DC analysis calculation. VoH (min) of CC3220S is 2.1V and VIH (min) of flash MX25R3235F is 0.8VCC = 0.8x3 = 2.4V
Here VoH<VIH
As per rule VOH>VIH to interface two chips. Here this rule is violating.
Please suggest us on this how this memory part MX25R3235F is validated with CC3220S.
