MSP430F6734IPNR

The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with extensive lowpower 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 wake-up from low-power modes to active mode in 3 µs (typical). The MSP430F67xx series are microcontroller configurations with three high-performance 24-bit sigma-delta A/D converters, a 10-bit analog-to-digital (A/D) converter, four enhanced universal serial communication interfaces (three eUSCI_A and one eUSCI_B), four 16-bit timers, hardware multiplier, DMA, real-time clock module with alarm capabilities, LCD driver with integrated contrast control, auxiliary supply system, and up to 72 I/O pins in 100-pin devices and 52 I/O pins in 80-pin devices. Typical applications for these devices are 2-wire and 3-wire single-phase metering, including tamper-resistant meter implementations.
