3 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
1 µs.
The MSP430G2231 devices are ultra-low-power
mixed signal microcontrollers with a built-in 16-bit
timer and ten I/O pins. The MSP430G2231 devices
have a 10-bit A/D converter and built-in
communication capability using synchronous
protocols (SPI or I2C). For configuration details, see
Table 1.
Typical applications include low-cost sensor systems
that capture analog signals, convert them to digital
values, and then process the data for display or for
transmission to a host system.
