They allow simultaneous sampling of multiple voltage and current channels — exactly what a three-phase energy meter needs for accurate active, reactive, and apparent power calculation. Each converter runs independently, so the CPU can process one phase while the others acquire. For a BOM that would otherwise require an external multi-channel ADC and a separate metrology AFE, this integration saves board area and reduces the component count. The 10-bit auxiliary ADC handles the housekeeping — temperature sense, DC bus monitoring — without loading the sigma-delta pipeline. End-of-life hot status; manufacturer lists as active. Base product number is MSP430F67691; 'A' suffix indicates a die revision. ## Supply voltage and power rail design Internal oscillator eliminates external crystal in many applications. Housed in a 100-pin LQFP with a 14x14 mm body. Surface-mount, fine-pitch — standard for a mixed-signal MCU of this complexity. The 62 general-purpose I/O lines give plenty of headroom for a parallel LCD, keypad matrix, or external memory interface. The LCD driver segment count is not specified in this listing, but the peripheral set includes it, so a segment display can be driven directly without a separate controller.","metaTitle":"TI MSP430F67691AIPZ 16-bit MCU, 25MHz, 512KB Flash, 6xSD ADC","metaDescription":"Texas Instruments MSP430F67691AIPZ 16-bit MCU with 25MHz CPUXV2 core, 512KB Flash, 32KB RAM, six 24-bit sigma-delta ADCs, industrial temp.
