Raspberry Pi RP2040 Microcontroller IC

Description

The RP2040 marks Raspberry Pi’s entry into the microcontroller market, delivering exceptional performance, low cost, and ease of use. This powerful chip features a symmetric dual-core ARM Cortex-M0+ processor running at 133MHz, complemented by 264KB of on-chip SRAM across six independent banks and support for up to 16MB of off-chip QSPI Flash memory. Its fully-connected AHB crossbar ensures efficient data flow, allowing cores and DMA engines to operate in parallel without contention.

Designed for flexibility, the RP2040 offers a comprehensive set of peripherals including 30 GPIO pins (4 with analog input capability), 2 UARTs, 2 SPI controllers, 2 I2C controllers, 16 PWM channels, and a USB 1.1 controller with host and device support. A standout feature is its eight Programmable I/O (PIO) state machines, enabling custom hardware interface emulation and high-speed data manipulation. Packaged in a compact 7mm x 7mm form factor, the RP2040 is backed by extensive documentation, a polished MicroPython port, and a UF2 bootloader in ROM, making it accessible for both professional developers and hobbyists.
