When selecting between ARM and RISC-V architecture MCUs from the perspective of end users, considerations should include project requirements, development resources, costs, and strategic planning.We will compare the differences between ARM and RISC-V architecture MCUs from various dimensions: ARM Architecture MCU RISC-V Architecture MCU Cost and Licensing Requires payment of core licensing fees (BOM cost … Read more
Preparation Work Hardware Confirm the MCU serial port (USART1, UART4, etc.); Confirm the “pins” (TX: transmit pin, RX: receive pin). For example: PA9, PA10; TX connects to RX, RX connects to TX, GND connects to GND; Note: Ensure common ground (GND), which is essential for the signal circuit and level reference. Protocol Format: Ensure that … Read more
“ In today’s highly digital world, we are surrounded by countless smart devices. From smartphones to autonomous vehicles, from IoT sensors to large-scale data centers, these technologies rely on various processing chips. However, faced with the dizzying abbreviations of CPU, MCU, MPU, SoC, DSP, ECU, GPU, and FPGA, even industry professionals can sometimes feel confused.” … Read more
This article introduces the working principle of a classic microcontroller power circuit, as shown in the figure below. Initial State (Power Off) Before the circuit is powered on, the “TEST” switch is open, and the MCU is not powered by VCC. At this time, the base of transistor T1 is grounded through R9 (100k), keeping … Read more
The power-on sequence of an MCU (Microcontroller Unit) is a carefully designed sequence that ensures the chip reliably transitions from a completely powered-off state to normal operating conditions. 1. Power-on Reset When power is applied to the MCU, the supply voltage rises from 0V to the rated operating voltage (e.g., 3.3V). The internal reset circuit … Read more
ROHM Semiconductor has developed a new reference design that uses a single microcontroller (MCU) to simultaneously control both sides of an AC-DC power supply, namely the power factor correction (PFC) AC-DC converter stage and the flyback DC-DC converter stage. ROHM states that by using a single controller to support two power stages, it can reduce … Read more
