A myth in the MSP430 MCU world, the benchmark for the lowest power consumption of 16-bit MCUs in the world, has never been surpassed in the past 20 years, is the well-deserved king of low power in the eyes of engineers. In the early years, TI introduced the MSP432, a 32-bit low-power MCU based on the ARM Cortex-M4F core. And the most significant difference between the two is here, let's take a look at it with Xiaobian~
Will the birth of this lower-power, better-performing MCU family break the myth of the MSP430 low-power king? Before the answer is revealed, let us first compare the two.
It can be clearly seen from the above table that MSP430 and MSP432 are different in product positioning and application advantages. There is no competition between the two. The emergence of MSP432 will not only replace MSP430, but will extend the concept and advantages of TI's low-power MCU from 16-bit to 32-bit.
“Low-power MCUs are an important part of TI's business. Currently, we can offer more than 500 low-power MCU products to our customers. Whether it is 16-bit or 32-bit products, we will continue to invest.†Ray Upton, vice president and general manager of the microcontroller business unit at TI.
Power consumption or performance? Crazy!
Developers have been making compromises and trade-offs between power consumption and performance all the time. In desperation, they can only choose one, either at the expense of some performance to reduce power consumption or to increase power consumption to meet high performance requirements. However, more and more applications have put forward high-performance and low-power design requirements, and developers have a headache in the face of such a dilemma.
"The MSP432 achieves the performance of the Cortex-M4F with power consumption similar to M0+, allowing developers to achieve ultra-low power and optimal performance at the same time without any compromise." TI Ultra Low Power MSP Microcontroller Division Manager Miller Adair.
Why? Lowest power consumption
Why? Optimum performance
MSP430 and MSP432: the same strain
As can be seen from the naming conventions of the two product families, both belong to TI's low-power MCU product portfolio. MSP432 is a continuation of MSP430 in product design and product concept. The MSP432 platform brings together TI's experience and IP results in designing the MSP430 over the past 20 years.
Moreover, because the MSP430 and MSP432 are driven by the same API, their code, registers, and low-power peripherals are compatible, so the client's software design can be seamlessly ported between MSP430 and MSP432.
In summary, the advent of the MSP432 did not threaten the MSP430's position as the leader of low-power in the 16-bit MCU field, but instead extended TI's leading position in ultra-low power to the 32-bit MCU field. Through the scalable product portfolio of MSP430 and MSP432, TI customers can select the most suitable MCU products according to the application domain and design requirements, and integrate more functions without affecting the user experience.
