The MSP430F5438A-EP is an ultralow-power microcontroller. The architecture, combined with
extensive 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 wake-up from low-power modes to active mode in 3.5 µs (typical).
The MSP430F5438A-EP is a microcontroller configuration with three 16-bit timers, a high
performance 12-bit analog-to-digital (A/D) converter, up to four universal serial communication
interfaces (USCI), hardware multiplier, DMA, real-time clock module with alarm capabilities, and up
to 87 I/O pins.
Typical applications for this device include analog and digital sensor systems, digital
motor control, remote controls, thermostats, digital timers, and hand-held meters.
