Overview of RP2040
The Raspberry Pi RP2040 is the company's first microcontroller. It brings to the microcontroller arena our distinctive values of great performance, low cost, and ease of use. It provides professional users with unrivaled power and flexibility because to its huge on-chip memory, symmetric dual-core processing complex, deterministic bus fabric, and comprehensive peripheral set reinforced with our innovative Programmable I/O (PIO) subsystem. It provides the lowest possible barrier to entry for beginning and amateur users, with thorough documentation, a polished MicroPython port, and a UF2 bootloader in ROM.
The RP2040 is a stateless device with external QSPI memory cached execute-in-place functionality. This design option allows you to select the right density of nonvolatile storage for your application while also taking advantage of commodity Flash's low pricing.
The RP2040 is built on a cutting-edge 40nm process node that delivers great performance, low dynamic power consumption, and low leakage, as well as a range of low-power modes to facilitate extended battery operation.
Overview of STM32
The STM32 32-Bit ARM® Cortex®-M MCUs from STMicroelectronics are based on the Arm Cortex-M processor and are designed to give MCU users unprecedented levels of freedom. The MCUs come in a 32-bit version that combines high performance, real-time capability, digital signal processing, and low-power, low-voltage operation. This is accomplished while retaining complete integration and development ease.
The STM32 range now includes Arm Cortex-M cores (M0, M0+, M3, M4, and M7), as well as other alternatives. This allows developers the freedom to choose the best STM32 for their applications. The ability to move applications from one device to another is given special consideration. When dealing with the STM32 family, the binary compatibility, paired with the comparable pinout assignment, hardware IP proliferation, and higher-level programming language, makes the development task significantly more convenient.
Couclusion of RP2040 VS STM32
RP2040 and STM32 are different in many aspects, such as the type of microcontroller, and Processor Series. The type of RP2040 microcontroller is Dual-core, while the type of STM32 is Signal core. The type of RP2040 Processor Series is Dual ARM Cortex-M0+ cores, while the type of STM32 Processor Series is ARM Cortex M. In addition, the some parameters of RP2040 is higher than STM32. The RAM Size of RP2040 is higher than STM32 with the 264 Kilobytes of RP2040 compared to 20 Kilobytes of STM32. The Flash Size of RP2040 is higher than STM32 with the 2MB of RP2040 compared to 64KB of STM32. However, the operating temperature of STM32 is higher than RP2040. The operating temperature of RP2040 is -20°C to +85°C, while the operating temperature of STM32 is -40°C to +85°C. So from the point of my view, I think that the RP2040 is better than STM32.
