25 MHz 16-bit core with four 24-bit sigma-delta ADCs
The MSP430F67481AIPEUR: Its standout feature is the set of four 24-bit sigma-delta analog-to-digital converters, purpose-built for polyphase energy metering, precision instrumentation, and industrial sensor front-ends where multiple high-resolution channels must be sampled simultaneously.
Peripheral set and connectivity for metering designs
Beyond the sigma-delta converters, the device integrates a 90-pin I/O set, an LCD driver for direct segment display, a DMA controller for moving conversion results without CPU intervention, and a brown-out detect and POR circuit for reliable power-up sequencing.
The 128-LQFP package (20x14 mm body) provides enough breakout for the 90 I/O lines while remaining hand-solderable in rework.
