The MSP430F67681IPZ is a 16-bit microcontroller from Texas Instruments that provides minimal power consumption and low cost. It has a 32-bit RISC core, integrated 32-bit timer, and up to 16KB of Flash memory with up to 512B of RAM. The low power consumption saves on energy costs in applications such as security systems, hardware communication interface, data acquisition, and industrial automation. The integrated 9/12-bit ADC allows for analog signal acquisition and can be used to measure temperature, humidity, and pressure. Other features include a number of communication interfaces such as SPI, UART, CAN, and I2C.
