Its distinguishing feature is the set of three 24-bit sigma-delta analog-to-digital converters integrated on-chip, purpose-built for direct current and voltage sensing in polyphase energy metering. Operating from 1.8 V to 3.6 V and rated over -40°C to 85°C, it is housed in a 100-pin LQFP (14x14 mm) package. ## Three 24-bit sigma-delta converters — no external AFE needed ## Package and memory fit for a BOM line The 128 KB Flash and 8 KB RAM are sized for a metrology application with a communication stack (e.g., Modbus RTU over UART) and a small LCD driver — the MCU includes an LCD controller as a peripheral. The 72 I/O provide ample room for tamper detection, relay drivers, and status LEDs without an external GPIO expander.","metaTitle":"Texas Instruments MSP430F67641AIPZR 16-bit MCU, 25 MHz, 128 KB Flash, 3x24-bit S","metaDescription":"TI MSP430F67641AIPZR 16-bit MCU with 3x24-bit sigma-delta ADC for energy metering. 25 MHz CPUXV2, 128 KB Flash, 8 KB RAM, 72 I/O, -40°C to 85°C.
