Flexible serial interfaces for easy system integration

Mature MSP430 ecosystem with tools, libraries, and reference designs

Stable operation across wide voltage and temperature ranges

Packaging

Type 20‑TSSOP surface‑mount IC for automated assembly

Case and size 20‑TSSOP, 4.40 mm body width (0.173 inch), low‑profile gull‑wing leads; typical lead pitch 0.65 mm; see datasheet for exact mechanical dimensions

Materials epoxy molding compound over copper leadframe, matte‑tin plated leads

Pin configuration 20 leads total with power pins (VCC, GND) and up to 16 GPIO; pins support ADC inputs and serial interfaces per MSP430G2xx pin map; refer to datasheet for pinout

Thermal characteristics ambient operating −40°C to +85°C; thermal resistance values for TSSOP provided in the datasheet; use adequate copper area and airflow for heat spreading

Electrical properties supply 1.8 V to 3.6 V, core up to 16 MHz, 8×10‑bit ADC, internal oscillator, brown‑out reset; absolute maximum ratings and ESD specs in datasheet

Shipment format Tape & Reel (TR) for high‑volume pick‑and‑place; embossed carrier tape with cover tape on standard reels; moisture handling per TI MSL guidelines
