The Texas Instruments MSP430 family of ultralow-power microcontrollers consists of several devices featuring
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 digitally controlled oscillator （DCO） allows wake-up from low-power modes to
active mode in 3.5 µs （typical）。
The MSP430F5529， MSP430F5527， MSP430F5525， and MSP430F5521 are microcontroller configurations with
integrated USB and PHY supporting USB 2.0， four 16-bit timers， a high-performance 12-bit analog-to-digital
converter （ADC）， two universal serial communication interfaces （USCI）， hardware multiplier， DMA， real-time clock
module with alarm capabilities， and 63 I/O pins. The MSP430F5528， MSP430F5526， MSP430F5524， and
MSP430F5522 include all of these peripherals but have 47 I/O pins.
The MSP430F5519， MSP430F5517， and MSP430F5515 are microcontroller configurations with integrated USB
and PHY supporting USB 2.0， four 16-bit timers， two universal serial communication interfaces （USCI）， hardware
multiplier， DMA， real time clock module with alarm capabilities， and 63 I/O pins. The MSP430F5514 and
MSP430FF5513 include all of these peripherals but have 47 I/O pins.
