It packs 128 KB of Flash program memory and 8 KB of RAM, with a peripheral set tailored for precision measurement and mixed-signal control: three 24-bit sigma-delta ADCs for direct sensor interface, plus an 8-channel 10-bit auxiliary ADC. Connectivity includes I²C, SPI, UART, and IrDA, and the device drives up to 72 general-purpose I/O lines. It operates from 1.8 V to 3.6 V over the industrial temperature range of -40°C to 85°C, housed in a 100-pin LQFP (14×14 mm) package. Typical applications include polyphase energy metering, power-quality monitoring, and industrial sensor hubs where the on-chip sigma-delta converters eliminate external analog front-end components. The 25 MHz CPUXV2 core services three simultaneous 24-bit sigma-delta conversions and handles communication stacks.","metaTitle":"Texas Instruments MSP430F67641IPZR 16-bit MCU, 25 MHz, 128KB Flash","metaDescription":"TI MSP430F67641IPZR 16-bit MCU with 25 MHz core, 128KB Flash, 8KB RAM, 3x24b sigma-delta ADC.
