The new RP2350 for Raspberry

The RP2350 processor from Raspberry Pi is a cutting-edge microcontroller that was officially announced on August 8, 2024, and released as part of the Raspberry Pi Pico 2 board. This processor represents a significant advancement in microcontroller technology, offering dual-core, dual-architecture capabilities with Arm Cortex-M33 cores and Hazard3 RISC-V cores, which can be selected via software or programmed into the on-chip OTP memory.

Detailed Specifications

The RP2350 features:

• Processing Power: Dual Arm Cortex-M33 cores running at 150MHz, with DSP instructions, single-precision floating-point instructions, and a simplified double-precision floating-point coprocessor for advanced calculations.
• Memory: 520KB of SRAM distributed across ten concurrently accessible banks, along with 8KB of one-time-programmable (OTP) memory.
• Flash Storage: Optional in-package 2MB QSPI NOR flash connected to the first chip select.
• Connectivity: Dual USB 1.1 controllers supporting host and device modes, two UART controllers, two SPI controllers, and one QSPI controller.
• Security Features: Arm TrustZone for secure processing, hardware SHA-256 accelerator, hardware random number generator (TRNG), and optional boot signing with protected OTP storage.
• Power Management: On-chip switched-mode power supply and programmable low-dropout regulator (LDO) to generate core voltage.

Variants

The RP2350 comes in four versions:

• RP2350A: 30 GPIO pins in a 7×7mm QFN-60EP package.
• RP2350B: 48 GPIO pins in a 10×10mm QFN-80EP package.
• RP2354A: Same package as RP2350A but includes 2MB of QSPI NOR flash.
• RP2354B: Same package as RP2350B but includes 2MB of QSPI NOR flash.
