MSP430F6459TPZR

The MSP430 family of ultra-low-power microcontrollers offers a wide variety of members, each equipped with different peripheral sets to meet the needs of various applications. The architecture, combined with five low-power modes, represents the optimal choice for extending battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU with 16-bit registers and a constant generator for maximum code efficiency. The DCO enables wake-up from low-power mode to active mode in 3µs (typical). The MSP430F6459-HIREL microcontroller integrates a 3.3V LDO, four 16-bit timers, a high-performance 12-bit ADC, three USCIs, a hardware multiplier, DMA, an RTC module with alarm functionality, a comparator, and up to 74 I/O pins.
