AI Summary

M031LE3AE by Nuvoton Technology Corporation: ARM® Cortex®-M0 - Microcontroller IC 32-Bit 48MHz 128KB (128K x 8) FLASH 48-LQFP (7x7).

The M032LE3AE belongs to Nuvoton's M032 USB series, sharing the exact ARM Cortex-M0 core architecture, 48 MHz clock speed, 128 KB Flash, 16 KB SRAM, and 1.8V to 3.6V operating range as the target part. It is a direct drop-in alternative in the same 48-LQFP footprint while providing additional crystal-less USB 2.0 hardware capability.

  • Direct pin-compatible drop-in replacement with identical LQFP48 (7x7mm) footprint and pinout assignment
  • Includes crystal-less Full-Speed USB 2.0 interface capability in addition to base M031 functionality
  • Identical ARM Cortex-M0 core speed (48 MHz), Flash size (128 KB), and SRAM size (16 KB)

The M031LG6AE is an upgraded variant in Nuvoton's M031 series using the same 48-LQFP footprint. It offers a drop-in migration path with doubled memory capacity (256 KB Flash / 32 KB SRAM) and higher max operating frequency (72 MHz).

  • Higher clock speed capability (72 MHz vs 48 MHz)
  • Double the Flash memory capacity (256 KB vs 128 KB) and SRAM capacity (32 KB vs 16 KB)
  • Direct pin-compatible drop-in replacement in the same 48-LQFP footprint

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
