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.The MSP430FG642x 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, an auxiliary supply system, up to 128KB of flash, 10KB of SRAM, and 73 I/O pins in 100‑pin devices and 113‑pin devices.Typical applications for these microcontrollers include small signal-monitoring applications such as handheld test and measurement equipment, field transmitters, and blood glucose meters. These microcontrollers can reduce overall system cost through high analog integration and enable long battery life by low-power operation.The MSP430FG662x and MSP430FG642x MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. Development kits include the MSP-TS430PZ100AUSB 100-pin target development board. TI also provides free
MSP430Ware™
software, which is available as a component of
Code Composer Studio™ IDE desktop and cloud versions within TI Resource Explorer. The MSP430 MCUs are also supported by
extensive online collateral, training, and online support through the
TI E2E™ support forums.For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
