+## chip info
19
+
20
+RP2350 is a high-performance, secure, low-cost, and easy-to-use microcontroller launched by Raspberry Pi.
21
+
22
+It features large on-chip memory, a symmetric dual-core processor, a deterministic bus structure, and a rich set of peripherals. It is also equipped with our unique Programmable I/O (PIO) subsystem, providing unparalleled power and flexibility for professional users. RP2350 offers detailed documentation, a complete MicroPython port, and a UF2 bootloader in ROM, providing the lowest entry barrier for beginners and hobbyists.
23
+
24
+RP2350 is a stateless device that supports execute-in-place (XIP) from external QSPI memory. This design allows you to choose the appropriate density of non-volatile storage for your application and benefit from the low prices of commodity flash components.
25
+
26
+RP2350 is manufactured using a modern 40nm process node, featuring high performance, low dynamic power consumption, and low leakage. It also offers multiple low-power modes to support long-term operation on battery power.
27
+
28
+Main features include:
29
+
30
+- **Dual Cortex-M33 or Hazard3 processors, up to 150MHz**
31
+- 520KB multi-bank high-performance SRAM
32
+- Supports up to 16MB external flash via dedicated QSPI bus
33
+- DMA controller
34
+- Fully connected AHB crossbar switch
35
+- On-chip programmable LDO for core voltage generation
36
+- 2 on-chip PLLs for generating USB and core clocks
37
+- 30 GPIO pins, 4 of which can be used as analog inputs
38
+- 2 UARTs
39
+- 2 SPI controllers
40
+- 2 I2C controllers
41
+- 24 PWM channels
42
+- USB 1.1 controller and PHY, supporting host and device modes
43
+- 3 Programmable IO (PIO) blocks, with a total of 12 state machines
44
+
45
+Security:
46
+
47
+RP2350 features a comprehensive security architecture built around Arm TrustZone for Cortex-M, including the following features:
48
+
49
+- Supports secure boot with signature verification
50
+- 8KB on-chip anti-fuse One-Time Programmable (OTP) memory
51
+- SHA-256 accelerator
52
+- Hardware True Random Number Generator (TRNG)
53
+
54
+Architecture switching:
55
+
56
+RP2350 includes a pair of open hardware Hazard3 RISC-V cores, which can replace the Cortex-M33 cores at boot. Our boot ROM can even automatically detect the architecture of the built second-stage binary and reboot the chip into the corresponding mode. Except for a small number of security features and the double-precision floating-point accelerator, all chip functions are available in RISC-V mode.
