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
m
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.
