description

The Texas InstrumentsMSP430 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 portablemeasurement 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 wake-up from low-power modes to active mode in less

than 6 μs.

The MSP430F42xA series are microcontroller configurations with three independent 16-bit sigma-delta A/D

converters, each with an integrated differential programmable gain amplifier input stage. Also included are a

built-in 16-bit timer, 128 LCD segment drive capability, hardware multiplier, and 14 I/O pins.

Typical applications include high-resolution applications such as handheld metering equipment, weigh scales,

and energy meters.
