MSP430x22x2, MSP430x22x4 Mixed Signal Microcontrollers are low-power, low-voltage microcontrollers with ultrafast wake-up time from standby mode and a 16-bit RISC architecture. The product supports various clock configurations and communication interfaces, and is equipped with a 10-bit A/D converter and configurable operational amplifiers. Additionally, it features security protection to prevent program reading.
The MSP430x22x2 and MSP430x22x4 are ultra‑low‑power mixed‑signal microcontrollers featuring a 16‑bit RISC CPU, two 16‑bit timers, a universal serial communication interface, a 10‑bit ADC, and up to 32 I/O pins. They are designed for battery‑powered sensor and measurement applications, offering multiple low‑power modes and fast wake‑up times.
The document provides detailed pin‑out diagrams, functional block diagrams, electrical specifications, and mechanical dimensions for both the 38‑pin TSSOP and 40‑pin QFN packages, along with regulatory notices and warranty information.
