Working Principle

The MSP430F6659IZQWT is based on a 16-bit RISC architecture and can operate at frequencies of up to13MHz. This provides the device with sufficient processing capabilities for many sophisticated applications, such as motor control and embedded image processing.The device also has excellent power consumption characteristics as it is able to run in low-power modes.The microcontroller operates in three main stages:fetch, decode and execute.

In the fetch stage, an instruction is fetched from the program memory.The bus arbitration logic then attempts to obtain the bus, based on priority and other factors.If the bus access is successful, then the instruction is sent to the instruction register and the address of the next instruction is determined.In the decode stage, the instruction is decoded and operands are read from the RAM, or written to the RAM.The instruction is then sent to the execution unit.In the execute stage, the instruction is executed and the result is written to the data register.The process then begins again.

Applications

Due to the features and working principle of the MSP430F6659IZQWT, it is ideal for use in many different embedded applications. These include, but are not limited to:

• Automotive control.
• Environment monitoring.
• Smart appliances.
• Motor control.
• Industrial robotics.
• Telecommunications.
• Mobile and networking.
• Sensing.

The MSP430F6659IZQWT is an excellent product for designers who wish to build energy-efficient products. It offers powerful features, a low-power architecture and excellent development tools and documentation, making it extremely suitable for the most demanding applications.
