description

The Texas Instruments MSP430 series is an ultralow-power microcontroller family consisting of several devices

featuring different sets of modules targeted to various applications. The microcontroller is designed to be battery

operated for an extended-application lifetime. With 16-bit RISC architecture, 16 bit integrated registers on the

CPU, and a constant generator, the MSP430 achieves maximum code efficiency. The digitally-controlled

oscillator provides fast wake-up from all low-power modes to active mode in less than 6 s.

Typical applications include sensor systems that capture analog signals, convert them to digital values, and then

process the data and display them or transmit them to a host system. Stand alone RF sensor front end is another

area of application. The I/O port inputs provide single slope A/D conversion capability on resistive sensors. The

MSP430x11x series is an ultralow-power mixed signal microcontroller with a built in 16-bit timer and fourteen

I/O pins. The MSP430x11x1 family adds a versatile analog comparator.

The flash memory provides added flexibility of in-system programming and data storage without significantly

increasing the current consumption of the device. The programming voltage is generated on-chip, thereby

alleviating the need for an additional supply, and even allowing for reprogramming of battery-operated systems.
