TMS320F28375D: Reduced timing requirements for SPI master mode

user5931564

We want to reduce the timing requirements for SPI master mode.

The device under development uses SPI normal mode (Non-High-speed Mode), but there is a problem that it can not meet the F28375D setup time specification (20 ns).
Can you reduce the timing requirements as follows?

Current status : Setup time 20ns (minmum)

↓

Request : Setup time 10ns (minmum)

*In addition, SPI High Speed Mode can not be used due to pin limitation.

Hi,

I do not think there is a way to reduce the setup time. As per the spec, the minimum setup time is 20n for non - high speed mode.

I will check with the design team for confirmation and get back to you.

Veena
