5 MSP430FR57xx Family

Beyond integrating FRAM as their main memory technology, the MSP430FR57xx family of devices have other unique features such as an extremely low active mode current consumption of ~100 µA/MHz. They also offer a rich mixture of peripherals including communication ports, timers, and a 10-bit ADC with integrated reference (see the block diagram in Figure 5-1).

The MSP430FR57xx family offers 20 different devices with FRAM memories up to 16 kB. The devices are offered in four packages ranging from a tiny 24-pin QFN to a 40-pin QFN, as well as 28-pin and 38-pin TSSOP packages. See the MSP430FR57xx data sheet for more information.
