3 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 devices to wake up from low-power modes to active mode in

3.5 μs (typical).

The MSP430F5329, MSP430F5327, and MSP430F5325 are microcontroller configurations with an integrated

3.3-V LDO, four 16-bit timers, a high-performance 12-bit ADC, two USCIs, a hardware multiplier, DMA, an RTC

module with alarm capabilities, and 63 I/O pins.

The MSP430F5328, MSP430F5326, and MSP430F5324 include all of these peripherals but have 47 I/O pins.

Typical applications include analog and digital sensor systems, data loggers, and various general-purpose

applications.
