3 Description
The Texas Instruments MSP430F55xx microcontrollers (MCUs) are part of the MSP430™ system control &
communication 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 USCIs, a hardware multiplier, DMA, an 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 USCIs, 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.
The MSP430F55xx MCUs are supported by an extensive hardware and software ecosystem with reference
designs and code examples to get your design started quickly. Development kits include the MSP430F5529 USB
LaunchPad™ development kit and the MSP430F5529 experimenter’s board as well as the MSPTS430PN80USB
80-pin target development board and the MSP-TS430RGC64USB 64-pin target development
board. TI also provides free MSP430Ware™ software, which is available as a component of Code Composer
Studio™ IDE desktop and cloud versions within TI Resource Explorer. The MSP430 MCUs are also supported by
extensive online collateral, training, and online support through the TI E2E™ support forum.
