Research institutions released data saying that global MCU shipments will reach 32 billion pieces in 2023. After decades of iteration and development, MCU now plays an irreplaceable role in the industrial chain of home appliances, automobiles, industrial equipment, etc. At present, as the size of circuit and system design is getting smaller and smaller and the requirements for performance improvement are becoming more and more urgent, the industry is still facing the dual challenges of performance and cost. The 8-bit and 16-bit MCUs remaining on the market are already difficult to meet the needs and urgently need the injection of new technologies.
Texas Instruments (TI)'s 32-bit MSPM0 series products were launched in this context. With its rich functions and scalability, it helps terminal products improve performance, reduce power consumption, increase integration and security to adapt to many application scenarios such as intelligence, Internet of Things and industrial control.
Large product group and rich specifications
The MSPM0 MCU is designed based on the Arm Cortex-M0 architecture. When it is released in March 2023, Arm's M0 architecture has been launched for more than ten years. "Why launch the M0 series chips with high market maturity at this time point" is the first question to be answered by this series of products. Now, after more than a year of development, this series of products has proven its industry advantages in terms of versatility, cost-effectiveness, scalability, low power consumption, and development-friendlyness through practice, and has been recognized by customers in the fields of industry, automobiles, consumer electronics, etc. with its huge product matrix.
TI's MSPM0 series MCUs offer two sub-series, G and L, at the time of release: the G series can achieve faster computing and the chip supports higher frequencies; the L series can sense lower currents and is more suitable for sensor applications, and accordingly, it supports lower frequencies. This series of products also offers flash memory capacities of different specifications from 8kb to 128kb, and different pin packaging options from 16 to 64, providing customers with a wealth of optional space. Since the release of MSPM0, the product line has been continuously expanded. This year, Texas Instruments has launched the MSPM0C110x series of microcontrollers based on innovative manufacturing technology and advanced process nodes with its deep embedded technology accumulation and keen insight into the technical challenges of the 8-bit and 16-bit MCU markets. This series of products features ultra-small packaging while maintaining extremely low costs, showing unique advantages in various space-sensitive application scenarios.
MSPM0 has launched more than 100 products, covering different packages, pin counts, temperature ranges, and peripherals such as analog and communication, while maintaining pin compatibility with the same package products. In December of the same year, Texas Instruments released the MSPM0 MCU that meets the AEC-Q100 standard to meet the application needs of body electronics products.
Reduce dynamic power consumption and static power consumption
With the increasing demand for intelligence in the fields of Internet of Things, industry, and automobiles, MCU, one of these semiconductor devices with a long working time, needs to continuously improve its energy efficiency performance to meet market demand. And low power consumption is precisely one of the outstanding advantages of the MSPM0 series of products.
The power consumption of MCU is roughly divided into two categories: dynamic power consumption and static power consumption. Among them, dynamic power consumption mainly refers to the current when the CPU and most peripherals are running; static power consumption mainly refers to the bias current and leakage current of analog and digital circuits when the CPU and most peripheral devices are turned off.
In order to reduce power consumption, TI chose a "two-legged approach": in terms of reducing dynamic power consumption, MSPM0 can quickly return to low power mode after completing the task. MSPM0 provides different clock sources, clock frequencies and power domains to achieve different power consumption levels. Users can set the product to switch between different power consumption modes (run, sleep, stop, standby and shutdown) and three low-power mode strategy options (XX0, XX1, XX2) to achieve lower dynamic power consumption. In terms of reducing static power consumption, the strategy of MSPM0 is to turn off unused modules and use these modules at the appropriate operating frequency and appropriate MCU operating mode.
Under the above overall design ideas, MSPM0 also adopts software coding strategies such as adjusting conditional code execution, non-blocking programming, and optimizing code size, and adjusts different components such as MCU power supply, resistors, capacitors, power IC, etc. to reduce power consumption, thereby achieving overall power consumption optimization of MSPM0 series products.
