The MSP430 incorporates a 16-bit RISC CPU, peripherals, and a flexible clock system that interconnect using a von-Neumann common memory address bus (MAB) and memory data bus (MDB). Partnering a modern CPU with modular memory-mapped analog and digital peripherals, the MSP430 offers solutions for demanding mixed-signal applications.
Key features of the MSP430x4xx family include:
??? Ultralow-power architecture extends battery life
?0.1-μA RAM retention
?0.8-μA real-time clock mode
?250-μA / MIPS active
??? High-performance analog ideal for precision measurement
?12-bit or 10-bit ADC — 200 ksps, temperature sensor, VRef
?12-bit dual-DAC
?Comparator-gated timers for measuring resistive elements
?Supply voltage supervisor
??? 16-bit RISC CPU enables new applications at a fraction of the code size.
?Large register file eliminates working file bottleneck
?Compact core design reduces power consumption and cost
?Optimized for modern high-level programming
?Only 27 core instructions and seven addressing modes
?Extensive vectored-interrupt capability
?In-system programmable Flash permits flexible code changes, field upgrades and data logging
