The standout feature is the three 24-bit sigma-delta ADCs — this part is designed for polyphase energy metering, power-quality monitoring, and precision sensor front-ends where multiple high-resolution simultaneous conversions are needed. Additional data conversion comes from an 8-channel 10-bit SAR ADC. The device operates from 1.8 V to 3.6 V over the industrial temperature range of -40°C to 85°C, and is packaged in a 100-LQFP (14×14 mm) with 72 I/O lines. ## What the 25 MHz core and 24-bit ADC bank mean for the BOM The 25 MHz CPUXV2 is not a high-throughput general-purpose core — it is a low-power signal-processing engine sized to service three simultaneous 24-bit sigma-delta conversions. Each ΣΔ converter runs independently, so the MCU can capture voltage and current on three phases without external multiplexing or a separate AFE. The 4 KB RAM is tight; the application code must stream conversion results out via I²C, SPI, or UART rather than buffering large blocks locally. Designs targeting single-phase metering or fewer channels can step down to a smaller MSP430F6xx variant, but the 3×ΣΔ bank is the reason to pick this specific order code.","metaTitle":"TI MSP430F67621AIPZR 16-bit MCU, 25 MHz, 64 KB Flash, 3x24b ΣΔ ADC","metaDescription":"TI MSP430F67621AIPZR 16-bit MCU, 25 MHz MSP430 CPUXV2, 64 KB Flash, 4 KB RAM, 3x24b sigma-delta + 8x10b ADC, 72 I/O, 1.8–3.6 V, -40°C to 85°C, 100-LQFP.
