An additional 8-channel 10-bit ADC handles auxiliary measurements. ## 90 I/O and connectivity set for smart meter communication The LCD driver peripheral built into the device drives segment displays directly, eliminating the need for a separate display controller in many meter designs. For existing designs that already qualify this MCU, the only sourcing path is the independent market — surplus inventory, new-old-stock, or broker channels. There is no official TI successor listed for this exact order code. ## Package and mounting — 128-LQFP (20×14 mm) 128-lead LQFP package with a 20 mm × 14 mm body, surface-mount. Tape & Reel suffix (IPEUR) for automated assembly.","metaTitle":"TI MSP430F67491IPEUR 16-bit MCU, 25 MHz, 512 KB Flash","metaDescription":"Texas Instruments MSP430F67491IPEUR 16-bit MCU with 25 MHz MSP430 CPUXV2 core, 512 KB Flash, 32 KB RAM, 4x24b sigma-delta ADC.

For new designs, you would need to evaluate current MSP430F6xx or MSP430FRxx family devices that include sigma-delta ADC peripherals. The pinout and peripheral set will differ, so a PCB redesign is expected — there is no drop-in alternative."},{"question":"Does MSP430F67491IPEUR support I2C communication?","answer":"Yes, the connectivity set includes I²C, along with SPI, UART/USART, LINbus, and IrDA interfaces.
