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 the device to wake up from low-power modes to active mode in
less than 1 μs.
The MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16-bit timers, up to
24 I/O capacitive-touch enabled pins, a versatile
analog comparator, a 10-bit analog-to-digital (A/D)
converter, and built-in communication capability using
the universal serial communication interface. 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.
