The MSP430x11x2/12x2 series are low-power 16-bit MCUs that include the MSP430F1122/F1132 and MSP430F1222/F1232 products. The series MCUs operate in the 1.8 V to 3.6 V power supply range and provide 200 µA active mode current, 0.7 µA standby mode current, and 0.1 µA power down mode current. The MSP430x11x2/12x2 series MCUs feature many low-power characteristics, including five power saving modes, a low standby mode wake-up time, and a 125 ns instruction cycle time.
The MSP430x11x2 and MSP430x12x2 are ultralow‑power mixed‑signal microcontrollers featuring a 16‑bit RISC CPU, 10‑bit ADC, and multiple low‑power modes. They are offered in several plastic and QFN packages with flash memory ranging from 4 KB to 8 KB and 256 B RAM.
The document provides pin‑out tables, functional block diagrams, terminal descriptions, operating mode details, mechanical dimensions, and legal notices. It is intended for designers and engineers who need detailed specifications for integration into portable measurement applications.
