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 five 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 MSP430F5310, MSP430F5309, and MSP430F5308 devices are microcontroller configurations with a

3.3-V LDO, 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 MSP430F5304 device is a configuration with a 3.3-V LDO, 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.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User's Guide.
