Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

SPI data rates are commonly in the range of 1 to 70 MHz and byte lengths can range from 8- and 12-bits to multiples of these values. Data transfers always consist of a data exchange. While the master ...

Serial Peripheral Interface, or SPI, is a very common communication protocol used for two-way communication between two devices. A standard SPI bus consists of 4 signals, Master Out Slave In (MOSI), ...

Serial peripheral interface (SPI) is one of the most widely used interfaces between microcontroller and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others. 4-wire SPI ...

At L-3 Communications, we use PLLs (phase-locked loops) in many of our products to generate precise, stable signals. To program these parts, we must load several control registers with digital words ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...

Two serial EEPROMs are SPI-bus based memory chips that permit easy interfacing with microcontrollers. The 25AA256 and 25LC256 are 256-Kb chips that operate at speeds up to 10 MHz. The 25AA256 operates ...

Remember old hard drives with their giant ribbon cables? They went serial and now the power cables are way thicker than the data cables. We’ve seen the same thing in embedded devices. Talking between ...
