CC2652P: The latency from SPI command till RF transmit

Albin Zhang

Part Number: CC2652P

Hi, There,

To realize a function of Wireless proprietary protocol, customer would like to know the latency form SPI (uDMA access) to RF transmit.

could you help to analyze the estimate number?

Thanks!

Hi Albin,

This is not an easy question to answer given the number of variables, including SPI bit rate and data frame size along with protocol PHY conditions and throughput. It would be best if they could create their own test conditions using the SPICC26X2DMA TI Driver API reference and rfPacketTx example.
