WebSPI is the “Serial Peripheral Interface”, widely used with embedded systems because it is a simple and efficient interface: basically a multiplexed shift register. Its three signal wires hold a clock (SCK, often in the range of 1-20 MHz), a “Master Out, Slave In” (MOSI) data line, and a “Master In, Slave Out” (MISO) data line. WebWhat is the max SPI throughput? If I go above a data rate of 8Mbps, I start to drop data. At 8Mbps, I get a throughput rate of about 27kbps which is very slow. At a data rate of 20Mbps, I still get less than 100kbps of throughput (that … m2 south beach

WebJul 18, 2024 · The minimum cycle time of the 8080 interface is given on page 61 of the datasheet: 240 ns @ 3.3V. It's the same for the 6800 interface, too. The 3-/4-wire interface clock period is a minimum of 50 ns (page 65), so in terms of byte transfers, it's going to be roughly 60% as fast as the parallel interface (400 ns per byte). WebAug 1, 2014 · To estimate the SPI throughput, we assume sometypical delays for the different components in Figure 3. Each tracedelay is assumed to be 0.25 ns, amounting to a total trace delay (t TRACE ) of 1 ns. Similarly, the slave delay (t SLAVE ) and master setup delay (t MASTER ) are assumed to be 3 ns and 2 ns respectively. m2s rt750
