The standout feature is the three 16-bit sigma-delta ADCs, purpose-built for voltage and current sensing in a watt-hour meter. An integrated LCD controller drives a segment display directly, saving an external driver chip and its board space. Communication runs over SPI or UART/USART; 14 general-purpose I/O handle the rest. Supply range is 1.8 V to 3.6 V, and the operating temperature covers -40 to 85 °C — industrial enough for outdoor meter enclosures and factory floors. ## What the 8.4 MHz core and 8 KB Flash mean for your BOM The CPU16 core runs at 8.4 MHz. The 8 KB Flash and 256 bytes RAM support single-phase metrology firmware. ## Package and mounting — 64-LQFP, 10×10 mm 64-lead LQFP with a 10×10 mm body. Surface-mount only.","metaTitle":"Texas Instruments MSP430FE423IPMR 16-bit MCU, 8.4MHz, 8KB Flash, 3×16-bit ADC","metaDescription":"TI MSP430FE423IPMR 16-bit MCU, 8.4MHz MSP430 CPU16, 8KB Flash, 256B RAM, 3×16-bit sigma-delta ADC, LCD controller, -40 to 85°C, 64-LQFP.
