Which Microcontroller should i use

Hi SK_Labs ,

There are different design options for implementing such a system. You can take a look at the following device and its associated typical application use.

In this case can you suggest which micro processor to be used ??

Hi SK_Labs ,

You can use any microcontroller that has a SPI peripheral.

For example, you can use https://www.analog.com/en/products/max32650.html#product-overview

For example on which pin we can connect RO and DI of MAX3140

Hi SK_Labs ,

You can use SPI0 (pins from P1.23 to P1.29) for the SPI connection, and RO to P2.11 and DI to P2.12, respectively.

Thanks for your reply.......Is there any less Package Microcontroller is available for this kind of application ?

On which pin we can connect RE and DE of MAX3140

On which pin we can connect RE and DE of MAX3140

Hi SK_Labs ,

The table shows UART0_CTS  as pin P2.9.
