Loosely which type of processor (M33)

floor(log2(RAM / 16KB))

floor(log2(nonvolatile / 128KB)) or 0 if no onboard nonvolatile storage

Specification

The RP2350 is a versatile, high-performance microcontroller from Raspberry Pi, designed to be secure, affordable, and user-friendly.

It boasts a large on-chip memory, a symmetric dual-core processor complex, a deterministic bus fabric, and a rich set of peripherals enhanced by the unique Programmable I/O (PIO) subsystem. This combination offers professional users exceptional power and flexibility. For beginners and hobbyists, the RP2350 provides an easy entry point with detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM.

As a stateless device, the RP2350 supports cached execute-in-place from external QSPI memory, allowing users to select the appropriate non-volatile storage density for their applications and benefit from the cost-effectiveness of commodity flash parts.

Manufactured on a modern 40nm process node, the RP2350 delivers high performance, low dynamic power consumption, and low leakage. It also features various low-power modes to support extended battery operation.

Key Features:

Dual Cortex-M33 or Hazard3 processors running up to 150MHz
520KB multi-bank high-performance SRAM
Support for up to 16MB of off-chip Flash memory via a dedicated QSPI bus
DMA controller
Fully-connected AHB crossbar
On-chip programmable LDO for core voltage generation
2 on-chip PLLs for USB and core clocks
30 GPIO pins, with 4 usable as analog inputs

Peripherals:

2 UARTs
2 SPI controllers
2 I2C controllers
24 PWM channels
USB 1.1 controller and PHY, supporting both host and device modes
3 Programmable IO (PIO) blocks, totaling 12 state machines

Security:

The RP2350 features a robust security architecture based on Arm TrustZone for Cortex-M, including:

Signed boot support
8KB of on-chip antifuse one-time-programmable (OTP) memory
SHA-256 acceleration
A hardware true random number generator (TRNG)

Architecture Switching:

The RP2350 includes a pair of open-hardware Hazard3 RISC-V cores that can be substituted at boot time for the Cortex-M33 cores. The boot ROM can auto-detect the architecture of a second-stage binary and reboot the chip into the appropriate mode. All chip features, except for a few security features and the double-precision floating-point accelerator, are available in RISC-V mode.
