Description

The MSP430F5438AMPZREP is a microcontroller with very low power consumption. The architecture is optimized for extended battery life in portable measurement applications, thanks to a variety of low-power modes. The device is equipped with a powerful 16-bit RISC CPU, 16-bit registers, and constant generators, all of which help to code efficiency. The digitally controlled oscillator (DCO) provides for a 3.5-second transition from low-power to active mode (typical).

The MSP430F5438AMPZREP is a microcontroller having three 16-bit timers, a 12-bit high-performance analog-to-digital (A/D) converter, up to four universal serial communication interfaces (USCI), a hardware multiplier, DMA, real-time clock module with alarm capabilities, and up to 87 I/O pins.
