(ACTIVE) 16 MHz Ultra-Low-Power Microcontroller with 16 KB FRAM, 2 KB SRAM, 60 IO, 10-bit ADC, IR Logic


Functional Diagram


The TI MSP430™ family of low-power microcontrollers consists of several devices that feature different sets of peripherals targeted for various applications. The architecture, combined with extensive low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The DCO allows the device to wake up from low-power modes to active mode in less than 10 µs.
