The F4xx family offers specific devices targeted at low power metering and measurement applications including heat meters, water meters (MSP430FWxxx), e-meters (MSP430FExxx) and glucose meters (MSP430FGxxx). The MSP430F4xx complements the F1xx family adding an LCD driver, zero power BOR on all devices and an enhanced Frequency Locked Loop (FLL) clock system. Also, the F4xx offers Flash memory, up to 16-MIPS (47xx), low voltage operation, a high-resolution 16-bit sigma-delta A-D converter, operational amplifiers, and other embedded analog functions ideal for single chip solutions.
