THVD1400: SPI Master to UART Converter for Gyroscope Sensor

Jayalakshmi Remesan
Prodigy 10 points
Part Number: THVD1400

Tool/software:

Please suggest an SPI to UART converter which can act as master for  IIM-42653 Gyroscope sensor , which communicates using SPI Protocol and functions as SPI Slave .

 looking for an IC  which can :

i) Functions as an SPI Master to communicate with IIM-42653 Sensor .

ii) Can operate with an SPI Clock of ( 24MHz) - as per the sensor's specification.

iii) Support the sensor Output data rate (ODR) of 32KHz ( as per the requirement)  - Support continuous SPI read throughput of atleast 3.58Mbps.

Additional References : Checked  with ICs : XRM20M1280 , SC16IS762IBS  but doesn't find master capabilities.

    There is no ready-made solution for this. SPI does not define when or how many bytes are transmitted in each direction. You would have to use a microprocessor and program it to speak both the IIM-42653 protocol and whatever protocol you want to use on the UART lines. (TI makes many microprocessors, but you should choose one based on what you already have experience with.)
