description
The Texas Instruments MSP430 family of ultralow power microcontrollers consist 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 wake-up from low-power modes to active mode in less
than 6
μ
s.
The MSP430F42x 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 is 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.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range
from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage
because very small parametric changes could cause the device not to meet its published specifications. These devices have limited
built-in ESD protection.
