Tips for Optimal High Speed SPI Layout Routing

WebSPI (serial peripheral interface) busses are a favorite ofdesigners for many reasons. The SPI bus can run at highspeed, transferring data at up to 60 Mbps over shortdistances like between chips on a board. The bus isconceptually simple, consisting of a clock, two data lines,and a chip select signal. Since data is presented on one phaseof the clock WebThe serial peripheral interface (SPI) bus provides high-speed synchronous data exchange over relatively short distances (typically within a set of connected boards), using a master/slave system with hardware slave selection (Figure 1.12).One processor must act as a master, generating the clock. Others act as slaves, using the master clock for timing the …
