AX58200

EtherCAT Slave Controller SoC

Quad Serial Peripheral Interface (QSPI)

2.21.1 Overview

The Quad Serial Peripheral Interface (QSPI) applies to synchronous serial data communication and allows full

duplex transfer. Devices communicate in Master/Slave mode with the 4-wire bi-direction interface. The

AX58200 contains one QSPI controller performing a serial-to-parallel conversion on data received from a

peripheral device, and a parallel-to-serial conversion on data transmitted to a peripheral device.

The QSPI controller supports 2-bit Transfer mode to perform full-duplex 2-bit data transfer and also supports

Dual and Quad I/O Transfer mode and the controller supports the PDMA function to access the data buffer.
