As mentioned earlier, the MSP430F2xx family provides twice the processing performance at half the stand-by power consumption compared to earlier MSP430F1xx devices. In addition, the MSP430F2xx family incorporates enhancements that reduce overall system cost and improve reliability making these new devices an ideal upgrade solution for existing MSP430 designs or as a launch point for a variety of new applications. The F2xx family will include members that are pin and functionally compatible with F1xx devices offering even lower power, more speed, BOR, and WDT+ on every device along with a variety of new peripherals. Unique F2xx derivatives with new peripherals such as a USCI (USART/SPI/I2C/IrDA), larger memory sizes (120kB Flash) and low pin count device variants will also be introduced.
