Working Principle

MSP430F5438ACY microcontroller adopts the advanced HLL (High Level Language) as the CPU core running environment language. On this basis, the advanced compiler system compiles and optimizes the code of each composed high-level language. After that, it will be converted into the 0 and 1 of the machine language and stored in the microcontroller’s ROM.

Compared to other kinds of general purpose microcontroller, MSP430F5438ACY has power saving design. In order to achieve ultra-low power consumptions, it integrates various power saving strategies: The MCU can detect the environmental changes to control the power off state or sleep state; The MCU can switches its clock frequency or shut down the peripheral modules automatically; The MCU can also adjusts the operating voltage and other measures.

The power-saving technology is based primarily on two principles: Managing the system\'s clock and managing the supply current. The clock is pulsed and timed using the DCO –Digital Controlled Oscillator, Oscillator - frequency generator, and External Digital Interface. The supply current is managed by controlling wake-up signals and supplying and shutting down clock signals. The Suspend response (SLP) signals CPU to enter the reduced power mode, which can significantly extend the battery life of the power supply.

MSP430F5438ACY has good features and flexibility, plus its low power consumption characteristics. It is widely used in the fields of industrial, medical and consumer electronics, smart sensors, communication devices and industrial automation systems.
