M430F5438AMZCARET

MSP430F5438A-ET is an ultra-low-power microcontroller. This architecture, used in conjunction with various low-power modes, is optimized to extend battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator that helps achieve excellent coding efficiency. This digitally controlled oscillator (DCO) can wake up from a low-power mode to an active mode in 3.5µs (typical). MSP430F5438A-ET is a microcontroller configuration with three 16-bit timers, a high-performance 12-bit analog-to-digital converter (ADC), up to four universal serial communication interfaces (USCI), a hardware multiplier, a DMA, a real-time clock (RTC) module with alarm functionality, and up to 87 I/O pins. For a complete module description, refer to the MSP430F5xx and MSP430F6xx Series User's Guide. The typical applications of this device include analog and digital sensor systems, digital motor control, remote control, thermostats, digital timers, and handheld meters.
