Why is the MSP430 low power?
Low power operation is a key feature of the MSP430. Its design gives very low leakage, and it operates from a single supply rail. This gives an extremely low current drain when the processor is in standby mode. Several low power modes are supported, which balance the needs of different applications.
What is the difference between smclk and aclk?
The master clock (MCLK) is derived from any of the four oscillators, and it drives the cpu. The sub-main clock (SMCLK) is derived from any of the four oscillators, and it drives peripherals. The auxiliary clock (ACLK) is derived from either VLOCLK or LFXT1CLK, and it drives peripherals.
What are the advantages of MSP430 microcontroller?
Advantages of the MSP430
The MSP430 Value Line controllers are cheaper than the higher-end ATMega controllers used in the Arduino platform.
You don't need an external crystal, because the MSP430 controllers can run at the full 16 Mhz from their internal clock source.
What is smclk MSP430?
MCLK is used by the CPU and system. SMCLK: Sub-main clock. SMCLK is software selectable as LFXT1CLK, VLOCLK, XT2CLK (if available on-chip), or DCOCLK. SMCLK is divided by 1, 2, 4, or 8. SMCLK is software selectable for individual peripheral modules.
