The TI MSP430 family of ultra-low-power microcontrollers consists of several devices featuring peripheral sets targeted for a variety of applications. The architecture, combined with extensive low-power modes, is optimized to achieve extended battery life in portable measurement applications. The microcontroller 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 devices to wake up from low-power modes to active mode in 3.5 µs (typical).
The MSP430F5529, MSP430F5527, MSP430F5525, and MSP430F5521 microcontrollers have 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), a hardware multiplier, DMA, a real-time clock (RTC) module with alarm capabilities, and 63 I/O pins. The MSP430F5528, MSP430F5526, MSP430F5524, and MSP430F5522 microcontrollers include all of these peripherals but have 47 I/O pins.
The MSP430F5519, MSP430F5517, and MSP430F5515 microcontrollers have integrated USB and PHY supporting USB 2.0, four 16-bit timers, two universal serial communication interfaces (USCI), a hardware multiplier, DMA, an RTC module with alarm capabilities, and 63 I/O pins. The MSP430F5514 and MSP430FF5513 microcontrollers 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.
