EOL status — sourcing reality for this line item
The MSP430F6748IPZ is end-of-life (EOL), flagged as a hot EOL part. No official successor is listed in the available records. For a BOM line that requires this exact order code, procurement must source through the independent channel. We can quote to order against an RFQ; availability and current pricing are confirmed at quote time. If a pin-compatible replacement within the MSP430F6xx family is needed, verify the exact peripheral set and memory map against the original design — the base product number MSP430F6748 shares the same footprint but density options vary.
4x24-bit sigma-delta ADC + LCD — purpose-built for metering
The four 24-bit sigma-delta converters enable simultaneous sampling of voltage and current on each phase of a three-phase plus neutral system, which is the core requirement for revenue-grade polyphase energy meters. The integrated segment LCD driver directly interfaces to a display for local readout, eliminating a separate display controller. The brown-out detect and POR circuits ensure the metrology data integrity during power dips. The internal oscillator reduces external BOM count — no external crystal is required for the basic timing, though an external watch crystal is typical for the real-time clock in billing applications.
