The MSP432MCU has a number of integrated features, including the MSP432P4's high-performance ADC and low power consumption, as well as the MSP432E4's high-performance Ethernet and wired connectivity, confirming it is the ideal host MCU for wireless applications. Its main features are high performance and low power consumption.
high performanceAccording to TI, the power consumption of the MSP432 is comparable to that of the general Cortex-M0+, but the performance is 10 times higher.
As shown in the figure, the performance is fully utilized by integrating such as ADC, comparator, ROM driver library, etc., the highest Coremark is 3.41/MHz.
The MSP432 core uses ARMM4F, which has a high performance M4. With floating-point arithmetic, the M4F has 10 times better performance than the competitor's M0+. Looking at the Coremark industry standard, the Coremark portion of the MSP432 can reach 3.41/MHz. But the kernel can't determine the overall performance, and the peripheral part of the kernel is equally important. TI spent a lot of time optimizing the periphery of this product. MSP432 products can be read and written simultaneously in the Flash section, and the original data can be deleted.
Put the MCU driver part in ROM instead of Flash, so that users can run their software faster when doing C programming. This allows the driver in ROM to execute 200% faster than in flash.
The MSP432 has a built-in 14-bit DAC that can achieve 13.2ENOB performance under actual measurement, while integrating a reference comparator to support differential inputs.
To achieve low power consumption, TI has integrated DC/DC in the MSP432 product, which reduces overall power consumption by 40% compared to previous LDOs. In the case of sleep, the previous practice still has to continue to supply power to ensure that the SRAM data can be retained. The MSP432MCU includes a unique optional RAM retention feature that provides dedicated power to each of the eight RAM segments required for operation, thereby reducing power consumption by 30nA per segment, reducing overall system power.
Many sensor applications require ADCs to collect data. The 14-bit ADC sampling speed in the MSP432 is five times faster than the original MSP430 ADC. When using a 14-bit ADC, the sampling sensor is only 375uA when running at 1MSPS. Power saving. At the same time, the sampling speed of the ADC is adjustable, even at the lowest power consumption can achieve 200μA level.
When the MCU is working, the driver will always run, so it will affect the power consumption of the MCU. The MSP432 puts the driver directly in the ROM and reduces the power consumption by 30% compared to placing the driver in the Flash. In this way, the saved Flash can be directly used by the user to store data or data. Especially exciting for engineers, whether it is MSP430 or MSP432, or wireless application MCU, TI's API driver is universal and compatible, which allows engineers to focus on their high-level language programming without paying attention to the underlying conversion work, saving them Development time.
