They allow direct connection of current and voltage transformer secondaries in a three-phase meter without an external analog front-end. The LCD driver further eliminates a separate display controller. For a BOM cost engineer, this part consolidates what would otherwise be an MCU plus an external ADC plus a display driver into a single 100-LQFP package — but only if the design can tolerate the 25 MHz CPU speed and 256 KB Flash ceiling. ## Obsolete — last-time-buy planning needed The MSP430F6746IPZR carries an obsolete lifecycle status. For a production line that depends on this exact order code, the window for last-time-buy orders has closed at the factory. Sourcing now runs through independent distribution on a quoted-to-order basis.","metaTitle":"TI MSP430F6746IPZR 16-bit MCU, 25 MHz, 256 KB Flash","metaDescription":"Texas Instruments MSP430F6746IPZR 16-bit MCU, 25 MHz CPU, 256 KB Flash, 16 KB RAM, 4x24-bit SD ADC, LCD driver.
