Description
AI
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 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 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.
For complete module descriptions, see theMSP430F5xx and MSP430F6xx Family User’s Guide.
(1)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.
