When it comes to low power operation, TI first wanted to optimize the silicon for low power with capabilities such as a wide voltage range. The MSP432 can run at 1.62 V, including the full speed as well as Flash access. Also there is an integrated DC/DC converter that allows greater efficiency while operating at speeds over 24 MHz. The Flash buffer NTMA helps minimize CPU cycles. Along with having low power silicon, TI wanted to provide low power tools and software. The driver library in ROM also consumes less power than if it were running out of Flash. Tools like ULP Advisor and EnergyTrace+ allow customers to optimize their code so that it does not consume extra power where it is unnecessary.
