The distinguishing feature on this part is the set of six 24-bit sigma-delta ADCs — that's the block that makes it a fit for polyphase energy metering, precision instrumentation, and industrial sensor front-ends where you need simultaneous multi-channel measurement. ## Peripheral set and connectivity Beyond the sigma-delta converters, the peripheral list includes a brown-out detect and reset, POR, DMA, an LCD driver, PWM timers, and a watchdog timer. For serial communication you get I²C, IrDA, LINbus, SPI, and UART/USART — enough to talk to external metrology AFEs, display drivers, and host controllers. There's also an internal oscillator, so you can save a crystal in cost-sensitive builds if the accuracy budget allows. The supply range of 1.8V to 3.6V lets it run from a single Li-ion cell or a 3.3V rail without an extra regulator, though the sigma-delta ADCs will need a clean analog supply for full 24-bit performance. ## Lifecycle reality — this part is obsolete The MSP430F67651IPEUR carries an Obsolete product status. There is no official TI successor listed for this exact order code, so the replacement path means evaluating a pin-compatible sibling in the MSP430F6xx family or migrating to a newer MSP430 generation. ## What the 25 MHz and 6x24-bit ADC mean for your design The 25 MHz core speed is modest by today's 32-bit standards, but the MSP430 architecture is lean — it can service the six sigma-delta ADCs, run the metrology algorithm, and drive an LCD segment display without breaking a sweat. The real value is the 24-bit resolution on six simultaneous channels: that lets you sample voltage and current on all three phases of a three-phase power system plus a neutral channel, all synchronously. If your application only needs one or two channels, you're paying for silicon you won't use, and a smaller MSP430 variant might be a better fit.","metaTitle":"MSP430F67651IPEUR 16-bit MCU, 25MHz, 128KB Flash","metaDescription":"TI MSP430F67651IPEUR 16-bit MCU with MSP430 CPUXV2 core at 25MHz, 128KB Flash, 16Kx8 RAM, 6x24-bit sigma-delta ADCs.
