MSP Integrated Analog Peripherals

MSP is a 16-bit family of microcontrollers designed from the ground up to support ultra-low-power applications. The integrated analog peripherals are designed to operate in the various power modes enabling a power-efficient system solution. Many of the analog peripherals have modes of operation that do not use the CPU at all, which enables low power consumption and frees the CPU for parallel operations. The information below highlights the key features of each analog integrated peripheral and recommended devices to begin evaluation.
