How do I select a microcontroller with low power consumption?
-for MSP430 series we can compare using \$\mu\$A/MHz at active state.
Similarly how to compare this with other MCU's like PIC and STM series i.e. other MCU's provide \$\mu\$A/MHz @ diff speed and have DMIPS for performance and MSP430 series doesn't provide any DMIPS parameter.
If \$\mu\$A/MHz==\$\mu\$A/MHz for ARM and MSP430 is it good to select ARM, as ARM is 32 bit where as MSP is 16 bit MCU?
