Expanded Serial Peripheral Interface (xSPI) Slave Controller

Description

The MAXVY's JESD251 Expanded Serial Peripheral Interface Slave controller is provides high data throughput, low signal count, and limited backward compatibility with legacy Serial Peripheral Interface(SPI) devices. It is used to connect xSPI Master devices in computing, automotive, Internet of Things, Embedded system and mobile system processor to non-volatile memories, graphics peripherals, networking peripherals,FPGAs, sensors devices.
