在嵌入式系统中，串行外设接口（Serial Peripheral Interface，SPI）及其扩展（如 DSPI 和 QSPI）被广泛应用于与外部设备（如传感器、存储器、LCD 控制器等）高速通信。 SPI（Serial Peripheral Interface）是一种全双工同步串行通信协议，通常由主设备（Master）和从设备（Slave ...

Electronics is everywhere, especially these days. Many times, as frequent users, we do not even notice a “paradigm change” in the things we use on regular basis. We use a fridge, but we do not care ...

The SPI is an interface bus that is used to send data between microcontrollers, and/or other peripherals like sensors, flash and EEPROM memory, LCDs, SD Cards, Camera Lenses and many more. Being able ...

The eSi-SPI core is a Serial Peripheral Interface that can be used to implement full-duplex, synchronous, serial communications between ICs. The eSi-S ...

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, ...

The 23LCV1024 is a 1 Mbit Serial Peripheral Interface (SPI) serial SRAM with battery backup and SDI interface. The memory of the device is accessed via a simple SPI compatible serial bus. The bus ...

In his most recent column, “A SPIFI new idea,” Jack Gannsle expresses his pleasure in the capabilities of a new flash memory interface from ST Microelectronics, which uses a Serial Peripheral ...

The Golden Gate family of serial peripheral interface bridge processors provides a means to connect PCI and PCI-X buses to the SPI3 and SPI4.2 high-speed serial network interfaces. The processors ...

The quad CAT5401 and CAT5411 64-tap, nonvolatile digital potentiometers are controlled over a serial peripheral interface (SPI) serial bus interface. Separate nonvolatile memory registers store each ...

The basic test instrument suite — a bench power supply, a good multimeter and perhaps an oscilloscope — is extremely flexible, but not exactly “plug and play” when it comes to diagnosing problems with ...
