The full name of stm32 is STMicroelectronics 32-bit series microcontroller chip.
ST is STMicroelectronics.
The STMicroelectronics Group was formed in June 1987 and was formed by the merger of SGS Microelectronics of Italy and Thomson Semiconductor of France. In May 1998, SGS-THOMSON Microelectronics changed the company name to STMicroelectronics, one of the world's largest semiconductor companies. Since its inception, ST has grown faster than the overall growth rate of the semiconductor industry. Since 1999, ST has been one of the top ten semiconductor companies in the world. According to the latest industrial statistics, STMicroelectronics is the world's fifth largest semiconductor manufacturer and is the world leader in many markets. For example, STMicroelectronics is the world's largest manufacturer of dedicated analog chips and power conversion chips, the world's largest supplier of industrial semiconductors and set-top box chips, and one of the world's leaders in discrete devices, cell phone camera modules and automotive ICs.
STMicroelectronics has nearly 50,000 employees, 16 advanced R&D facilities, 39 design and application centers, 15 major manufacturing facilities, and 78 sales offices in 36 countries. The company is headquartered in Geneva, Switzerland, and is also the headquarters of European and emerging markets; the company's US headquarters is located in Carrollton, Dallas, Texas; the Asia Pacific headquarters is located in Singapore; and the Japanese business is based in Tokyo. The China headquarters is located in Shanghai and is responsible for the business in Hong Kong, China and Taiwan.

ST is one of the industry's broadest semiconductor product lines, from discrete diodes and transistors to complex system-on-chip (SoC) devices to complete platform solutions including reference designs, application software, manufacturing tools and specifications. Its main product types are more than 3,000. STMicroelectronics is a leading supplier to a wide range of industries, with a wide range of advanced technologies, intellectual property (IP) resources and world-class manufacturing processes. Semiconductor products can be broadly divided into two categories: specialty products and standard products.
Dedicated products integrate a large number of proprietary IPs from semiconductor manufacturers and users and third parties, distinguishing them from other products on the market, such as system-on-a-chip (SoC) products, custom and semi-custom circuits, and specialized standard products ( ASSP), such as: wireless application processor, set-top box chip and automotive IC, microcontroller, smart card IC, dedicated memory, dedicated discrete device (ASD?). Once a customer uses a dedicated product in an application, product replacement is usually not possible without modifying the hardware and software design.
In contrast, standard products are devices that implement a specific, commonly used function, which is typically provided by several vendors. Often, standard products from manufacturers can be replaced by similar products from other manufacturers. The difference between suppliers is mainly in cost and customer service. However, once the application design is frozen, the standard device will become the only device in terms of performance optimization. Standard products include: discrete devices such as transistors, diodes and thyristors, power transistors such as MOSFETs, Bipolar and IGBTs, analog circuit building blocks such as operational amplifiers, comparators, voltage regulators and voltage reference circuits, standard logic functions and interfaces, Numerous memory products such as standard or serial NOR flash, NAND flash, EPROM/EEPROM and non-volatile RAM, RF discrete devices and ICs.
Since its inception, STMicroelectronics has successfully achieved a balance in market development, differentiated specialized products (these products are usually not susceptible to market cycles) and traditional standard products (these products require less The combination of R&D investment and production capital intensity). ST's diverse product portfolio avoids over-reliance on general or specialty products.
M is the microcontroller.
　　 A microcontroller is a single-chip microcomputer that integrates the main part of a microcomputer on a single chip. Microcontrollers were born in the mid-1970s. After more than 20 years of development, their cost is getting lower and lower, and their performance is getting stronger and stronger, which makes their applications ubiquitous in all fields. Examples include motor control, bar code readers/scanners, consumer electronics, gaming equipment, telephones, HVAC, building security and access control, industrial control and automation, and white goods (washing machines, microwave ovens).
Microcontroller units (MCUs) can be classified from different aspects: according to the data bus width can be divided into 8-bit, 16-bit and 32-bit machines; according to the class of embedded program memory can be divided into OTP, mask, EPROM /EEPROM and Flash Flash; according to the instruction structure, it can be further divided into CISC (Complex InstrucTIon Set Computer) and RISC (Reduced InstrucTIon Set Computer) microcontrollers. So M32 is a 32-bit microcontroller.
The STM32 family is a 32-bit microcontroller from ST's ARM Cortex-M3 core specifically designed for embedded applications requiring high performance, low cost, and low power. Divided into different products by kernel architecture:
Among them, STM32F series include: STM32F103 "Enhanced" series, STM32F101 "Basic" series, STM32F105, STM32F107 "Connected" series
The enhanced series clock frequency reaches 72MHz, which is the highest performance in its class. The basic clock frequency is 36MHz. It is a 16-bit product with a significantly higher performance than a 16-bit product. It is the best choice for 32-bit users. Both series have built-in 32K to 128K flash memory, the difference being the combination of the maximum capacity of the SRAM and the peripheral interface. When the clock frequency is 72MHz, the code is executed from the flash memory. The STM32 consumes 36mA, which is equivalent to 0.5mA/MHz.
Prior to the STM32F105 and STM32F107 interconnected series of microcontrollers, STMicroelectronics has introduced the STM32 basic series, enhanced series, USB basic series, and complementary series; the new series follows the enhanced series of 72MHz processing frequency. Memory includes 64KB to 256KB of flash and 20KB to 64KB of embedded SRAM. The new series is available in LQFP64, LQFP100 and LFBGA100 packages. Different packages maintain pinout consistency. Combined with the design philosophy of the STM32 platform, developers can re-optimize functions, memory, performance and pin count by selecting products with minimal Hardware changes to meet individual application needs.
