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 ...
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.

Tens of thousands of California residents will be forced to decide whether to permanently relocate or face construction bills after a wildfire crisis that’s weakened California’s insurance.
The PSoC 4 features a 32-bit ARM Cortex-M0 CPU, with programmable analog blocks (operational amplifiers and comparators), programmable digital blocks (PLD-based UDBs), programmable routing and flexible GPIO (route any function to any pin), a serial communication block (for SPI, UART, I²C), a timer/counter/PWM block and more.
