RP2040

admin — Thu, 22 Feb 2024 11:44:00 +0000

High performance. Low cost. Small package.

Flexible I/O connects RP2040 to the physical world by allowing it to speak to almost any external device. High performance breezes through integer workloads. Low cost helps ease the barrier to entry.

This isn’t just a powerful chip: it’s designed to help you bring every last drop of that power to bear. With six independent banks of RAM, and a fully connected switch at the heart of its bus fabric, you can easily arrange for the cores and DMA engines to run in parallel without contention.

RP2040 builds Raspberry Pi’s commitment to inexpensive, efficient computing into a small and powerful 7 mm × 7 mm package, with just two square millimetres of 40 nm silicon.
