The Texas Instruments MSP430FG662x and MSP430FG642x microcontrollers (MCUs) are part of the MSP430TM Metrology and Monitoring portfolio. The architecture and integrated peripherals, combined with five extensive low-power modes, are optimized to achieve extended battery life in portable and battery-powered 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 devices to wake up from low-power modes to active mode in less than 5 µs.

The MSP430FG662x MCUs are targeted at small signal-monitoring applications and include a 16-bit sigma-delta ADC, dual low-power operational amplifiers, dual 12-bit DACs, voltage comparator, four USCIs (two USCI_A modules and two USCI_B modules), four 16-bit timers, a hardware multiplier, a DMA module, an RTC module, an LCD driver with integrated contrast control for up to 160 segments, integrated full-speed USB, an auxiliary supply system, up to 128KB flash, 10KB SRAM and 73 I/O pins in 100‑pin devices and 113‑pin devices.
