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 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 the device to wake up from low-power modes to active mode in less than 5 µs. The MSP430F5510, MSP430F5509, and MSP430F5508 devices are microcontroller configurations with integrated USB and PHY supporting USB 2.0, four 16-bit timers, a high-performance 10-bit analog-to-digital converter (ADC), two universal serial communication interfaces (USCIs) [In the 48-pin packages, the USCI functions that are pinned out are limited to what the user configures on port 4 with the port mapping controller. It may not be possible to bring out all functions simultaneously.], a hardware multiplier, DMA, a real-time clock (RTC) module with alarm capabilities, and 31 or 47 I/O pins. The MSP430F5507, MSP430F5506, MSP430F5505, and MSP430F5504 devices are microcontroller configurations with integrated USB and PHY supporting USB 2.0, four 16-bit timers, a high-performance 10-bit ADC, one USCI, a hardware multiplier, DMA, an RTC module with alarm capabilities, and 31 I/O pins. The MSP430F5503, MSP430F5502, MSP430F5501, and MSP430F5500 devices include all of the MSP430F5507, MSP430F5506, MSP430F5505, and MSP430F5504 peripherals, except that they have a comparator instead of the 10-bit ADC. Typical applications include analog and digital sensor systems and data loggers that require connectivity to various USB hosts.
