Communication with a host or concentrator goes over I²C, SPI, UART, or IrDA — no built-in PHY for Ethernet or PLC, so you add an external modem chip for AMI networks. 25 MHz clock drives the 4x24-bit ADC pipeline and LCD refresh. No dedicated display controller needed. The MSP430F67481AIPZR is marked as end-of-life (EOL). That means the manufacturer has stopped production, and new units are only available through surplus or broker channels. There is no official TI successor listed for this specific variant, so a pin-compatible drop-in replacement is not guaranteed; you'd need to evaluate the wider MSP430F6xx family or consider a redesign if long-term supply is critical.","metaTitle":"Texas Instruments MSP430F67481AIPZR 16-bit MCU, 25 MHz, 512 KB Flash, 100-LQFP","metaDescription":"MSP430F67481AIPZR 16-bit MCU from TI MSP430F6xx series. 25 MHz CPU, 512 KB Flash, 16 KB RAM, 4x24-bit SD ADC, LCD driver.
