The MSP430 Family
Shown below is the family tree of MSP430 series microcontrollers from TI.
The most common MSP430 micros are the MSP430FR series, MSP430F series, MSP430G series and
the newly introduced MSP432 series.
MSP430FR series micros mainly feature high reliability, high endurance, 10-year data retention non-
volatile FRAM (ferroelectric random-access memory) memories. This series offer 16-bit solutions for
ultra-low-power sensing and system management in areas like smart building management systems,
smart grids, military and industrial designs. They feature the lowest standby power consumption of
about 350 nA with RTC, 100 µA/MHz active power consumption and the unique ability to save and
instantly restore system state right after power failures.
MSP432 series micros are the perfect combinations of MSP430 low-power portfolio with advanced
mixed-signal features and the high-performance processing capabilities of 32-bit ARM M4F engine.
These micros have high measurement precisions and contain high performance peripherals like high
resolution differential ADCs, DMA, IOT connectivity, etc. This series fills the gap between 16-bit
MSP430s and 32-bit ARM architecture and as of this moment this series is the most recent
development in the MSP430 family.
CC430 series is a small series of MSP430s with almost all features one can find in a typical MSP430
micro and embedded sub-GHz radio transceievers. They are well-stuffed true System-on-Chip (SOC)
solutions that remove the necessity of additional off-board wireless solutions.
Yet another tiny series of MSP430 micros include MSP430Cxx and MSP430Lxx micros. These micros
are intended for extreme low voltage (0.9 – 1.65V) operations. With just one Nickel Cadmium (NiCd)
battery it is possible to run any micro of this series. They feature low resolution analogue frontends
and low pin counts.
