The 8x10-bit auxiliary ADC handles housekeeping channels. ## Integration checklist for the 100-LQFP footprint The 100-LQFP package (14x14 mm body) with 62 GPIOs gives plenty of room for a segmented LCD direct-drive interface, external serial memory, and isolated communication links. The internal oscillator eliminates the crystal for most metering applications, though the sigma-delta converters benefit from an external precision reference for best accuracy. Brown-out reset and the programmable watchdog are on-chip — no external supervisor needed for basic safety integrity.","metaTitle":"Texas Instruments MSP430F67491IPZ 16-bit MCU, 512KB Flash, 25MHz","metaDescription":"TI MSP430F67491IPZ 16-bit MCU, 512KB Flash, 32KB RAM, 25MHz, 4x24b sigma-delta ADC, 100-LQFP, -40 to 85°C.
