1.3 Description

The TI MSP430™ family of ultra-low-power microcontrollers consists of several devices that feature 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 3 µs (typical).

The MSP430F6459-HIREL is a microcontroller configured with an integrated 3.3-V LDO, four 16-bit timers, a high-performance 12-bit ADC, three USCIs, a hardware multiplier, DMA, an RTC module with alarm capabilities, a comparator, and up to 74 I/O pins.

Typical applications for these devices include analog and digital sensor systems, digital motor control, remote controls, thermostats, digital timers, and hand-held meters.
