description
The Texas Instruments MSP430 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 wake-up from low-power modes to active mode in less
than 6μs.
The MSP430F47xx series are microcontroller configurations targeted to single phase electricity meters with
three or four 16-bit sigma-delta A/D converters. Each channel has a differential input pair and programmable
input gain. Also integrated are two 16-bit timers, three universal serial communication interfaces (USCI), 72 I/O
pins, and a liquid crystal driver (LCD) with integrated contrast control.
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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
