The six ADCs stream data for real-time response. ## Lifecycle reality: obsolete, not active No last-time-buy window remains open through the factory channel. Any procurement for a BOM line that carries this code will go through the surplus and independent distributor market. There is no official TI-recommended replacement listed in the lifecycle record; a cross-reference search against the MSP430F6xx family may yield a pin-compatible variant with similar ADC count, but that needs to be validated against the specific firmware and PCB layout. ## Six 24-bit sigma-delta ADCs — the design anchor The six 24-bit sigma-delta converters are the reason this part exists. They are intended for simultaneous sampling of three voltage and three current channels in a three-phase meter. The digital filter inside the modulator decimates the bitstream to a word rate that the CPU can read without a separate DSP. The 62 I/O lines give room for a segment LCD driver, tamper detection switches, and a communication module without an external port expander.","metaTitle":"Texas Instruments MSP430F67671IPZR 16-bit MCU, 25 MHz, 256 KB Flash, EOL","metaDescription":"MSP430F67671IPZR 16-bit MCU with 6×24b sigma-delta ADC, 256 KB Flash, 32 KB RAM, 25 MHz, -40 to 85°C.
