Can it identify parts with different packages?

Yes, it recognizes manufacturer package codes. Parts with the same manufacturer and series but different packages typically receive a high similarity score of 0.9.

Does it handle cross-manufacturer comparisons?

While it prioritizes same-family matching, it can perform cross-family comparisons using Levenshtein similarity, though these scores are capped to reflect the architectural differences.

Which microcontroller families are supported?

The skill supports major MCU families including PIC (16, 18, 24, 32), STM (8, 32), Atmel/AVR (ATMEGA, ATTINY, XMEGA), and MSP430/432.

How is the similarity score calculated?

The core logic uses a weighted formula: Family similarity (50%), Series number proximity (30%), and Feature code matching (20%).

Calculates similarity scores between microcontroller part numbers to identify replacements and feature-matched alternatives.

The MCU Similarity Calculator skill provides a specialized framework for analyzing and comparing microcontroller part numbers (MPNs) within the lib-electronic-components library. It utilizes manufacturer-specific logic to parse nomenclature for major families like STM32, PIC, and AVR, evaluating similarity based on family groups, series numbers, and feature codes such as Flash memory or USB capability. This skill is essential for hardware engineers and developers who need to find pin-compatible replacements, official alternatives, or similar-performance MCUs during design phases or supply chain optimizations.
