RP2350B microcontroller - ARM Cortex M33 + RISC-V Hazard3, QFN-80

Description

The RP2350B is an advanced microcontroller from the RP2350 family developed by Raspberry Pi, which is an improved version of the RP2040. The system uses two ARM Cortex-M33 cores and two RISC-V Hazard3 cores clocked at 150 MHz, which provides high performance in applications requiring real-time processing. The microcontroller is equipped with 520 KB of SRAM memory, divided into 10 independent banks, and up to 16 MB of external QSPI flash/PSRAM memory. Additionally, the system includes hardware security features such as SHA-256, protection against fault injection attacks, and the ability to assign peripherals to different security domains.

Kamami is the official distributor of Raspberry Pi minicomputers and dedicated accessories.

The RP2350B offers a wide range of peripherals, including 2x UART, 2x SPI, 2x I²C, 24 PWM channels, and 12 PIO state machines, making it an ideal choice for embedded applications, device control, and communication with other devices. The device is available in a QFN-80 (10 x 10 mm) package and supports 48 GPIO lines and 8 analog inputs.
