# Genesys Logic Manufacturer Skill ## MPN Structure Genesys Logic MPNs follow this general structure: ``` [PREFIX][SERIES][MODEL][PACKAGE][-OPTIONS] | | | | | | | | | +-- Optional: -QFN88, -REEL, -TR | | | +-- Package letter: G=LQFP, Q=QFN, S=SSOP | | +-- Model digits (varies by series) | +-- Series: 85, 35, 32, 33, 36, 98 +-- GL prefix (all Genesys Logic products) ``` ### Example Decoding ``` GL850G | | || | | |+-- G = LQFP package | | +-- 0 = base model | +-- 85 = USB 2.0 hub series +-- GL = Genesys Logic prefix GL3523-QFN88 | | | | | +-- QFN88 = 88-pin QFN package | +-- 3523 = USB 3.1 Gen 1 7-port hub +-- GL = Genesys Logic prefix ``` --- ## Product Families ### GL85x Series - USB 2.0 Hubs | Part Number | Ports | Features | |-------------|-------|----------| | GL850G | 4 | USB 2.0 4-port hub, LQFP | | GL852G | 4 | USB 2.0 4-port hub (improved) | ### GL35xx Series - USB 3.0/3.1 Hubs | Part Number | Ports | USB Version | Features | |-------------|-------|-------------|----------| | GL3510 | 4 | USB 3.0 | Basic 4-port hub | | GL3520 | 4 | USB 3.0 | 4-port hub with MTT | | GL3523 | 7 | USB 3.1 Gen 1 | 7-port hub with MTT | | GL3590 | 4 | USB 3.0 | 4-port hub | ### GL36xx Series - USB 3.1 Gen 2 Hubs | Part Number | Ports | USB Version | Features | |-------------|-------|-------------|----------| | GL36xx | varies | USB 3.1 Gen 2 | 10 Gbps support | ### GL32xx Series - USB 2.0 Card Readers | Part Number | Description | Features | |-------------|-------------|----------| | GL3220 | Card reader | USB 2.0 | | GL3224 | Card reader | USB 2.0 | | GL3227 | Card reader | USB 2.0 | ### GL33xx Series - USB 3.0 Card Readers | Part Number | Description | Features | |-------------|-------------|----------| | GL33xx | Card reader | USB 3.0 | ### GL98xx Series - USB Power Delivery Controllers | Part Number | Description | Features | |-------------|-------------|----------| | GL9801 | USB PD controller | Power delivery | | GL9802 | USB PD controller | Power delivery | --- ## Package Codes ### Single-Letter Suffixes (3-digit models) | Code | Package | Notes | |------|---------|-------| | G | LQFP | Low-profile QFP (GL850G, GL852G) | | Q | QFN | Quad flat no-lead | | S | SSOP | Shrink SOP | | T | TQFP | Thin QFP | ### Hyphenated Package Codes (4-digit models) | Code | Package | Notes | |------|---------|-------| | -QFN | QFN | Generic QFN | | -QFN88 | QFN-88 | 88-pin QFN | | -LQFP | LQFP | Generic LQFP | | -SSOP | SSOP | Generic SSOP | ### Tape and Reel Suffixes | Suffix | Meaning | |--------|---------| | -REEL | Tape and reel packaging | | -TR | Tape and reel (alternate) | --- ## USB Version Reference | Series | USB Version | Speed | |--------|-------------|-------| | GL85x | USB 2.0 | 480 Mbps | | GL3510, GL3520 | USB 3.0 | 5 Gbps | | GL3523, GL3590 | USB 3.1 Gen 1 | 5 Gbps | | GL36xx | USB 3.1 Gen 2 | 10 Gbps | | GL32xx | USB 2.0 | 480 Mbps | | GL33xx | USB 3.0 | 5 Gbps | --- ## Handler Implementation Notes ### Pattern Matching ```java // GL850/GL852 series - USB 2.0 hubs (GL850G, GL852G) "^GL85[0-9][A-Z].*" // GL35xx series - USB 3.0/3.1 hubs (GL3510, GL3520, GL3523, GL3590) "^GL35[0-9]{2}.*" // GL36xx series - USB 3.1 Gen 2 hubs "^GL36[0-9]{2}.*" // GL32xx series - Card readers (GL3220, GL3224, GL3227) "^GL32[0-9]{2}.*" // GL33xx series - USB 3.0 card readers "^GL33[0-9]{2}.*" // GL98xx series - USB PD controllers (GL9801, GL9802) "^GL98[0-9]{2}.*" ``` ### Package Code Extraction ```java // Step 1: Remove -REEL, -TR suffixes String cleanMpn = mpn.replaceAll("-?(REEL|TR)$", ""); // Step 2: Check for hyphenated package (GL3523-QFN88) int hyphen = cleanMpn.indexOf('-'); if (hyphen > 0) { String afterHyphen = cleanMpn.substring(hyphen + 1); String packageType = afterHyphen.replaceAll("[0-9]+$", ""); // Remove pin count return packageType; // e.g., "QFN" } // Step 3: Check for 3-digit + letter format (GL850G) if (cleanMpn.matches("^GL[0-9]{3}[A-Z]$")) { String suffix = cleanMpn.substring(cleanMpn.length() - 1); return resolvePackageCode(suffix); // G -> LQFP } ``` ### Series Extraction Returns specific series identifiers: - GL850G -> "GL850" - GL852G -> "GL852" - GL3510 -> "GL3510" - GL3523 -> "GL3523" --- ## Port Count Reference | Series | Downstream Ports | |--------|-----------------| | GL850, GL852 | 4 | | GL3510, GL3520 | 4 | | GL3523 | 7 | | GL3590 | 4 | --- ## MTT Support (Multiple Transaction Translator) MTT allows better performance when multiple USB 2.0 devices are connected behind a USB 3.0 hub. | Part | MTT Support | |------|-------------| | GL850G, GL852G | No | | GL3510 | No | | GL3520 | Yes | | GL3523 | Yes | | GL3590 | No | --- ## Related Files - Handler: `manufacturers/GenesysLogicHandler.java` - Component types: `IC` --- ## Official Replacements ### Upgrade Paths | Original | Replacement | Notes | |----------|-------------|-------| | GL850G | GL852G | Same port count, improved features | | GL3510 | GL3520 | Same port count, adds MTT | ### Package Variants Parts with same series but different packages are interchangeable functionally: - GL850G (LQFP) can be replaced by GL850Q (QFN) with PCB redesign - GL3523-QFN88 is the standard package for GL3523 --- ## Common Use Cases ### USB Hub Designs | Application | Recommended Part | Notes | |-------------|-----------------|-------| | Basic USB 2.0 hub | GL852G | 4-port, improved GL850 | | USB 3.0 hub | GL3520 | 4-port with MTT | | Multi-port USB 3.0 | GL3523 | 7-port with MTT | | High-speed USB 3.1 | GL36xx | USB 3.1 Gen 2 | ### Card Reader Designs | Application | Recommended Part | Notes | |-------------|-----------------|-------| | USB 2.0 card reader | GL3220 | Basic USB 2.0 | | USB 3.0 card reader | GL33xx | Higher speed | --- ## Learnings & Edge Cases - **3-digit vs 4-digit**: GL85x uses 3-digit model + package letter (GL850G), while GL35xx uses 4-digit model + hyphenated package (GL3523-QFN88). - **Package suffix position**: For 3-digit models, package letter is concatenated; for 4-digit models, package comes after hyphen. - **Pin count in package**: QFN88 means 88-pin QFN - the number is pin count, not part of package type. - **Tape and reel**: -REEL and -TR suffixes should be stripped before extracting package code. - **MTT importance**: For USB 3.0 hubs with many USB 2.0 devices, MTT support (GL3520, GL3523) provides better performance. - **GL852 vs GL850**: GL852G is an improved version of GL850G with better compatibility - use GL852G for new designs. <!-- Add new learnings above this line -->
