STM32MP 157DAA 1 working temperature

The chip generates heat when it works. For example, if the ambient temperature is 25℃, the wafer temperature may reach 50℃ after the chip works.

In June 2007, ST released the world's first 32-bit universal microcontroller chip based on ARM Cortex M3 core: STM32F 103, which quickly occupied the market with excellent performance, abundant resources and high cost performance. From then on, it was a blockbuster and it was out of control. By June 2020, the cumulative shipment of STM32 has exceeded 4.5 billion pieces. At present, STM32 has become synonymous with 32-bit ARM microcontroller. Many companies will say that they will use STM32 when recruiting. These enterprises may not necessarily use STM32 in actual project development, but if the applicant has mastered the development method of 32-bit ARM chips, it is easy to switch to other models of 32-bit ARM chips in actual development. As for why STM32 series can stand out among many semiconductor manufacturers, we will not analyze the commercial factors. In short, STM32 is very popular. Of course, it needs to be hard while the iron is hot, and the excellent performance of STM32 itself is also very important. The Excellence of STM32 is reflected in the following aspects:

1, ultra-low price. The price of 8-bit computer and the performance of 32-bit computer are the biggest advantages of STM32.

2, many peripherals. STM32 has many peripherals and functions, including: FSMC/FMC, timer, SPI, IIC, USB, CAN, IIS, SDIO, ADC, DAC, RTC, DMA, RGBLCD, SAI, JPEG decoding and so on. It is highly integrated.

3. Rich models. STM32 only has F 100, f10/,F 102, F 103, F 105, F 107, F2/. At the same time, STM32 also introduced M3 chips with ultra-low power consumption and wireless application, such as STM32L and STM32W. In addition, ST also introduced higher performance chips such as STM32F4/F7/H7. In 20 19, ST launched the first Cortex-A kernel of STM32 family and the MPU of STM32MP 1 series which can run Linux system, pushing the STM32 family to a new height!

4. Excellent real-time performance. Dozens or even hundreds of interrupts (depending on the specific chip), programmable priority, and all pins can be used as interrupt inputs.

5. Excellent power control. Each peripheral of STM32 has its own independent clock switch, which can reduce power consumption by turning off the clock of the corresponding peripheral.

6. Extremely low development cost. The program can be downloaded through serial port, and the corresponding emulator is also very cheap, supporting JTAG &；; SWD debugging interface can realize the simulation debugging of at least two IO ports, which greatly reduces the development cost.
