1 Introduction

Serial flash devices are one of the most preferred boot media in the embedded system applications. For mmwave sensors as well, the user application components are expected to be stored in the serial data flash which is interfaced with the sensor over the QSPI interface. The sFlash can also be used to store other data based on user’s choice. One example would be to store RF-Front end calibration data onto the sFlash and restoring by application during initial calibration cycle of the RF-Front end at every device bootup. This application note lists out verified sFlash devices parts to be working with the mmwave sensors, documents the prerequisites for other sFlash parts, and mentions any known issues.
