The MSP430 microcontroller is used to reduced power consumption, smaller size and cost-effective product. The microcontroller combines a number of precision components like comparators and analogue -to- digital converters with the versatility of a 16-bit CPU, Flash memory and many digital modules. The Key features of MSP430 microcontroller are:
1.16-bit RISC CPU
2.Current drawn is less than 0.1 µA in ‘off’ mode and less than 0.5µA in ‘standby’ mode
3.The Microcontroller can wake up in less than 1µs from power-down to full-speed functional mode.
4.Zero-power –brownout detection circuit.
MSP 430 is designed to extensively support interrupt-driven burst processing. It ensures ultra-low-power operations the system. The key features of its 16-bit CPU are:
1.No accumulator bottleneck
2.RISC architecture with:
*27 core instructions
*24 emulated instructions
*7 addressing modes
*Constant generator
3.Single-cycle register operations
4.Memory-to-memory atomic addressing
5.Bit, byte and word processing was described the Flash programmer-cum-emulator for MSP430 family devices that can be built with readily available components.
