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.
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. This is meant for digital video output. 12 PIO (programmable input–output) state machines. 24 PWM channels.
Two SPI controllers. One QSPI (quad SPI) controller (SSI), supports 1 / 2 / 4-bit SPI transfers, 1 chip select. Two I²C controllers. Eight PIO (programmable input–output) state machines. (NOTE: RP2350 family has 12). 16 PWM channels. (NOTE: RP2350 family has 24). 4-channel 12-bit 500-ksps SAR ADC, extra channel is connected to internal ...
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.
A drug trafficking investigation in Bogalusa, Louisiana, has led to the arrest of the city's mayor, Tyrin Truong, and several other people, police said Tuesday.

Finely grate 2 teaspoons of zest from 1 lemon, cover, and set aside. Juice both lemons and measure 1/4 cup lemon juice. In a small bowl, whisk together the tahini, lemon juice, soy sauce, garlic ...
Spansion HyperFlash memory devices provide a migration path—from single Quad SPI to Dual Quad SPI to HyperFlash Memory—allowing system applications to be scaled to different levels of flash performance when paired with compatible controllers, giving OEMs the ability to offer different product models with a single design.
