MSP430F249-EP — Enhanced product 16-bit
ultra-low-power microcontroller, 60-KB flash, 2-KB
RAM
The MSP430F23x/24x(1)/2410 series of
microcontrollers has two built-in 16-bit timers, a fast 12-bit
analog-to-digital converter (except the MSP430F24x1), a comparator,
four universal serial communication interface (USCI) modules (two in
the MSP430F23x) and as many as 48 I/O pins.
The Texas
Instruments MSP430™ ultra-low power microcontroller family 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 calibrated digitally
controlled oscillator (DCO) allows wake-up from low-power modes to
active mode in less than 1 µs.
