MSP430 Architecture
digital I/O
- The working of digital input output pins is performed with button input signal and LED for displaying output value. When the button clicks LED glows which is the operation of the combinational logic of the digital circuit.
timer
- For the timer working use a microcontroller for making a timing circuit. the timing circuit is high-power and comes to use for different industrial control and household devices. Digital ICS uses timing circuits and PLDs. PLC also uses a timing circuit and a timer is the best option for seeing the practical working of a timer.
Interrupt
- Any controller working is defined based on the repetition of program execution and instruction execution in the program’s needed time. If the program not work for some instructions the working of instructions will not completed, which delays the operations. For the controller to work fast in normal program applications use the interrupt function of the microcontroller.
RS232 communication
- Microcontrollers come with USART interfacing. The MSP439 comes with two USART interfaces. USART interfacing is not connected with the PC RS232 interface directly. The use of the USART interface helps to transmit data between the controller and the PC
A/D conversion
- MSP430 has a multi-channel 12-bit A/D converter and these A/D converters help the controller to work analog, display and check current and voltage, and other signals.
PCI, I2C interface, and LCD interface
- With this interfacing, we can easily connect external devices and provdie extra features for the controller.

- Arduino UNO has a clock speed of 16MHz and MSP430G2553’s clock speed is 16MHz.
- Arduino comes with low power modes and MSP430G2553 comes with different low power modes.
- For waking from standby mode Arduino UNO uses more time than the MSP430G2553 launchpad.
- Arduino uses Arduino IDE programming and MSP430G2553 uses Energia( similar to Arduino IDE)
