1.3 Description
The TI MSP 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 lowpower
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 ADC, two
USCIs (1), a hardware multiplier, DMA, an 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.
