AWR2243: SOP Signals in Cascade Configuration

robert hoff

Part Number: AWR2243

Hello,

In a cascade configuration, would there ever be a situation where the SOP signals for different AWR chips would not be the same, or can these signals be tied together?

Thanks,

Robert

Hello Robert,

If you are always loading the firmware over SPI interface and not using the serial flash to store the firmware then you can use came SOP controls for all chips. Please note that SOP pins should not be driven strongly on the board or from host, they must be driven via a series 10k ohms resister since after bootup these pins became output from the AWR device.

regards,

Vivek

Additionaly , its recommended to have separate nReset controls for multiple AWr chips.
