TI MSP430F5338IPZR

TI MSP430 series ultra-low-power microcontrollers come in a wide variety. Each member device is equipped with different peripheral sets to meet the needs of various applications. This architecture, when used in conjunction with five low-power modes, is the optimal choice for extending battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, using 16-bit registers and a constant generator for maximum coding efficiency. The digitally controlled oscillator (DCO) can wake up from a low-power mode to an active mode in 3µs (typical).

MSP430F533x devices are microcontrollers equipped with the following peripherals: an integrated 3.3V low-dropout regulator (LDO), a high-performance 12-bit ADC, a comparator, two USCI, a hardware multiplier, DMA, four 16-bit timers, an RTC module with an alarm function, and up to 74 I/O pins.
