MSP430F5338IZQWT Texas Instruments 16bit MCU

MSP430F5338IZQWT Overview

The TI MSP430? family of ultra-low-power microcontrollers 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 digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3 μs (typical).

The MSP430F533x devices are microcontrollers with an integrated 3.3-V LDO, a high-performance 12-bit ADC, a comparator, two USCIs, a hardware multiplier, DMA, four 16-bit timers, an RTC module with alarm capabilities, and up to 74 I/O pins.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
