This slide highlights the Vcc vs. CPU freq relationship of the 5xx family as compared to the existing 2xx. All MSP430 devices, including the F5xx operate in the wide range of 1.8 to 3.6V. Fundamental improvements were made to the F5xx including Flash programming at the minimum Vcc of 1.8V, increased CPU clock at both the upper and lower Vcc ends & a widened max CPU clock range of 25MHz at 2.2 – 3.6v. 12 MHz operation is possible even at the lowest Vcc of 1.8V. Compared to the F2xx, only 4MHz operation is possible at the min Vcc of 1.8v, and the min Flash programming voltage was 2.2V (vs. 2.7V on the 4xx). On the 2xx, full speed 16MHz operation is only possible at 3.3v or higher. Also shown is the core voltage programmability that the regulator in the PMM has enabled. This provides the user the ability to optimize the Vcore level to the performance needed by the given application for maximum power efficiency. This profile is for the first 5xx devices to be available: the F54xxA.
