What this MSP430F6746IPEU brings to a metering or sensor front-end
Its distinguishing feature is the integrated 4x24-bit sigma-delta ADC block, purpose-built for polyphase energy metering and precision multi-channel sensor acquisition.
The sigma-delta ADC — why this part gets specified
The four 24-bit sigma-delta converters allow simultaneous sampling of voltage and current channels in a three-phase system.
Active lifecycle — no end-of-life watch needed
Texas Instruments lists the MSP430F6746IPEU as an Active product. The base product number MSP430F6746 covers a density and peripheral family, so if a future firmware revision needs more memory or a different ADC configuration, a pin-compatible migration within the MSP430F6xx series is possible without a board spin.
Package and footprint for the layout engineer
The device comes in a 128-pin LQFP package with a 20x14 mm body (supplier device package 128-LQFP). It is a surface-mount, fine-pitch package that requires careful solder-paste stencil design and a reflow profile matching the component's moisture sensitivity level. The 90 I/O lines fan out on all four sides, so a four-layer board with a solid ground plane under the package is the usual starting point.
Sourcing this part for a production BOM
The MSP430F6746IPEU is an active, current-production device from Texas Instruments. If you need a small quantity for a prototype or a repair, the same RFQ process applies; the order code is the same whether you buy one tray or a production reel.
