SPI is a very useful and flexible standard, but its flexibility stems from its simplicity. Four channels of unidirectional moderate speed isolation will handle SPI to clock rates of a couple of MHz.

The Serial Peripheral Interface (SPI) interface was initially standardized by Motorola in 1979 for short-distance communication in embedded systems. In its most common four-wire configuration, ...

High bandwidth data transfers have led to migration from existing packet interface standards to advanced ones. SPI (System Packet Interface) v4.2 has, for many years, remained an industry standard for ...

Using SPI interface to free FPGA routing resources is allowing over 90% utilization, fast timing closure and supports modular design approach without consequences. When doing designs with FPGA you are ...
