MSP430 is an ultralow-power mixed signal microcontroller family with features such as low supply voltage range, ultra low-power consumption, multiple power saving modes, and 16-bit RISC architecture. The family consists of devices with different configurations targeted for various applications. The document describes the features and characteristics of the products.
The MSP430x31x family is an ultra‑low‑power mixed‑signal microcontroller line from Texas Instruments. It features a 16‑bit RISC CPU, up to 51 instructions, sixteen registers, and five power‑saving modes that enable operation from 2.5 V to 5.5 V with wake‑up times under 6 µs.
Typical applications include sensor systems that convert analog signals to digital values for processing or display. The device is offered in several packages (56‑pin SSOP, 48‑pin SSOP, 68‑pin JLCC) and includes integrated LCD drivers, a slope A/D converter, and on‑board programming support.
