What sets this part apart is the peripheral set: seven 24-bit sigma-delta analog-to-digital converters, plus an additional 8×10-bit ADC, a segment LCD controller, and a DMA engine. The 90 I/O lines and connectivity options (I²C, IrDA, LINbus, SPI, UART/USART) make it a fit for polyphase energy metering, industrial process control, and precision sensor front ends that need simultaneous multi-channel conversion. ## Package and footprint Housed in a 128-LQFP (20×14 mm body) — a standard fine-pitch QFP that routes easily on a four-layer board. Surface-mount, so no through-hole rework; the 0.5 mm pitch needs a decent soldering profile but is well within the capability of any contract assembler. ## Lifecycle and sourcing That means no last-time-buy clock is ticking; it remains a viable choice for both prototype builds and production runs.","metaTitle":"Texas Instruments MSP430F67781AIPEU 16-bit MCU, 25MHz","metaDescription":"Texas Instruments MSP430F67781AIPEU 16-bit MCU, 25MHz, 512KB Flash, 16KB RAM, 7×24b sigma-delta ADC, 90 I/O, -40 to 85°C, 128-LQFP.
