Course Aim – The MSP430 microcontroller is ideally suited for development of low-power embedded
systems that must run on batteries for many years. There are also applications where MSP430
microcontroller must operate on energy harvested from the environment. This is possible due to the ultralow
power operation of MSP430 and the fact that it provides a complete system solution including a RISC
CPU, flash memory, on-chip data converters and on-chip peripherals.
UNIT 7:
Motivation for MSP430microcontrollers – Low Power embedded systems, On-chip peripherals (analog
and digital), low-power RF capabilities. Target applications (Single-chip, low cost, low power, high
performance system design).
