Abstract：The series of MSP430 single chip are ultra—low power consumption mixed singal micro—controlIers，with a lot
of on—chip external components，they will be widely used．The paper introduces the small～scale and low—power data acquisi—
tion system，which is based on MSP430F449 single chip．It also introduces the signal processing，data sampling，serial commu—
nicating and data proposing in detail．Practice pmves that
it is available in battery power supply and portable equipment situa—
tions，typical applications include sensor systems that capture analog signals．
