This document describes the features and characteristics of the MSP430x20x1, MSP430x20x2, and MSP430x20x3 mixed signal microcontrollers, including low supply voltage range, ultralow power consumption, multiple power-saving modes, fast wake-up from standby mode, 16-bit RISC architecture, clock module configurations, timer, comparator, analog-to-digital converter, universal serial interface, brownout detector, and on-chip emulation logic.
The MSP430x20x series are ultralow‑power mixed‑signal microcontrollers featuring a 16‑bit RISC CPU, on‑chip analog comparator (x20x1) or communication interfaces (x20x2/x20x3), and a 10‑bit or 16‑bit ADC. They target sensor systems, portable measurement applications, and RF front‑ends, offering supply voltages from 1.8 V to 3.6 V and multiple low‑power modes.
The manual includes functional block diagrams, detailed pin‑out tables for TSSOP, DIP and QFN packages, terminal function descriptions, mechanical dimensions, and the standard Texas Instruments product notice and warranty information.
