Description

The TI MSP430™ family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five 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 digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3 µs (typical).

The MSP430F563x devices are microcontrollers with a high-performance 12-bit ADC, a comparator, two USCIs, USB 2.0, a hardware multiplier, DMA, four 16-bit timers, an RTC module with alarm capabilities, and up to 74 I/O pins.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
