[136] QSPI: QSPI has limited supply voltage range

This anomaly applies to IC Rev. Revision 1, build codes CLAA-D00, QKAA-D00.

Domains

Application

Symptoms

The QSPI interface is non-functional. The error depends on temperature, voltage and device.

Conditions

VDD voltage is higher than 2.0 V, and the clock frequency is set to 96 MHz.

Consequences

The QSPI interface may operate incorrectly because digital timing is not met.

Workaround

Use one of the following:
  • Use VDD voltage between 1.7 V and 2.0 V.
  • Use QSPI clock frequency of 48 MHz.
