Description
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. Typical applications include analog and digital sensor systems, data loggers, and others that require connectivity to various USB hosts.
