A Queued Serial Peripheral Interface (QSPI; different to but has same abbreviation as Quad SPI described in § Quad SPI) is a type of SPI controller that uses a data queue to transfer data across an SPI bus. [19] It has a wrap-around mode allowing continuous transfers to and from the queue with only intermittent attention from the CPU.
One USB 1.1 (LS & FS) controller and PHY, host and device support, 1.5 Mbps (Low Speed) and 12 Mbps (Full Speed). Two UART controllers. Two SPI controllers. One QSPI (quad SPI) controller, supports 1 / 2 / 4-bit SPI transfers, 2 chip selects. Two I²C controllers. One HSTX (high-speed serial transmit) controller, output-only.
Flash Magic, a commercial program for Windows and macOS to perform in-system programming of the LPC flash via its UART. nxp_isp_loader, an open-source tool to flash LPC microcontrollers over the UART. Debugging tools (JTAG / SWD) OpenOCD, an open source software package for JTAG access using a wide variety of hardware adapters.
Devices implementing SPI are typically specified with line rates of 700~800 Mbit/s and in some cases up to 1 Gbit/s. The latest version is SPI 4 Phase 2 also known as SPI 4.2 delivers bandwidth of up to 16 Gbit/s for a 16 bit interface. The Interlaken protocol, a close variant of SPI-5 replaced the System Packet Interface in the marketplace.

Atmel provides a series of JTAG adapters for the AVR: The Atmel-ICE [28] is the latest adapter. It supports JTAG, debugWire, aWire, SPI, TPI, and PDI interfaces. The JTAGICE 3 [29] is a midrange debugger in the JTAGICE family (JTAGICE mkIII). It supports JTAG, aWire, SPI, and PDI interfaces. The JTAGICE mkII [30] replaces the JTAGICE and is ...
Block diagram of an HD44780U-based LCD module. The Hitachi HD44780 LCD controller is limited to monochrome text displays and is often used in copiers, fax machines, laser printers, industrial test equipment, and networking equipment, such as routers and storage devices.
The SPI-5 standard (which describes up to Ultra-640) deprecates single-ended devices, so some devices may not be electrically backward compatible. Some host adapters offer compatibility using a SCSI bridge to electrically split the bus into an SE and an LVD half, so LVD devices can operate at full speed. [ 11 ]
