# Chipone Technology Manufacturer Skill ## MPN Structure Chipone MPNs follow this general structure: ``` [PREFIX][SERIES][VARIANT][PACKAGE] | | | | | | | +-- Package suffix (SS=SSOP, S=SOP, Q=QFN) | | +-- Variant letter (B, C for improved versions) | +-- Series number (2024, 2053, 2110, etc.) +-- Prefix: ICN or ICND (improved series) ``` ### Example Decoding ``` ICN2053SS | | || | | |+-- SS = SSOP package | | +-- (no variant letter) | +-- 2053 = 16-channel LED driver with S-PWM +-- ICN = Constant current LED driver prefix ICND2110-S | | || | | |+-- S = SOP package | | +-- (hyphen separator) | +-- 2110 = 16-channel improved LED driver +-- ICND = Improved series prefix ``` --- ## Product Families ### ICN2xxx Series - Constant Current LED Drivers | Part Number | Channels | Features | |-------------|----------|----------| | ICN2012 | 12 | Basic LED driver | | ICN2018 | 18 | Basic LED driver | | ICN2024 | 24 | 24-channel constant current | | ICN2026 | 26 | 26-channel constant current | | ICN2038 | 38 | 38-channel constant current | | ICN2053 | 16 | S-PWM for high grayscale | | ICN2065 | 16 | High refresh rate support | ### ICND2xxx Series - Improved LED Drivers | Part Number | Channels | Features | |-------------|----------|----------| | ICND2025 | 24 | Improved ICN2024 replacement | | ICND2053 | 16 | Improved ICN2053 replacement | | ICND2110 | 16 | Enhanced 16-channel driver | --- ## Package Codes | Code | Package | Notes | |------|---------|-------| | SS | SSOP | Small outline shrink package | | S | SOP | Small outline package | | SOP | SOP | Explicit SOP | | SSOP | SSOP | Explicit SSOP | | Q | QFN | Quad flat no-lead | | QFN | QFN | Explicit QFN | | T | TSSOP | Thin shrink small outline | | TSSOP | TSSOP | Explicit TSSOP | ### Package Suffix Positioning Package codes appear in two ways: 1. **Inline**: Directly after the part number (ICN2053SS) 2. **Hyphenated**: After a hyphen (ICND2110-S) --- ## Variant Letters | Letter | Meaning | |--------|---------| | B | Second revision | | C | Third revision | | (none) | Original revision | Single letters like B, C after the part number typically indicate variant revisions, NOT packages. **Example**: `ICN2065B` = ICN2065 revision B --- ## Official Replacements The ICND2xxx series are drop-in replacements for the corresponding ICN2xxx parts: | Original | Replacement | Notes | |----------|-------------|-------| | ICN2053 | ICND2053 | Pin-compatible, improved performance | | ICN2024 | ICND2025 | Similar functionality | Parts with the same base number in ICN vs ICND series are typically compatible. --- ## Handler Implementation Notes ### Pattern Matching ```java // ICN2xxx patterns "^ICN2[0-9]{3}[A-Z0-9-]*$" // ICND2xxx patterns (improved series) "^ICND2[0-9]{3}[A-Z0-9-]*$" ``` ### Package Code Extraction ```java // Step 1: Check for hyphenated suffix first // ICND2110-S -> S -> SOP // Step 2: Check for inline suffix // ICN2053SS -> SS -> SSOP // Step 3: Skip single variant letters // ICN2065B -> B is variant, not package -> return "" ``` ### Series Extraction ```java // ICND2xxx -> "ICND2" // ICN2xxx -> "ICN2" ``` --- ## Related Files - Handler: `manufacturers/ChiponeHandler.java` - Component types: `IC`, `LED_DRIVER` --- ## Common Use Cases ### LED Display Panels Chipone drivers are commonly used in LED display panels and signage: - Indoor LED screens: ICN2053, ICND2053 (high grayscale) - Outdoor LED screens: ICN2024, ICN2038 (high channel count) - High refresh displays: ICN2065 (high refresh rate) ### BOM Matching When matching BOMs, consider these equivalents: ``` ICN2053 == ICND2053 (drop-in replacement) ICN2053SS == ICN2053-SSOP (same package, different notation) ``` --- ## Learnings & Edge Cases - **Variant vs Package**: Single letters after the part number (B, C) are variants, not packages. Multi-letter suffixes (SS, QFN) are packages. - **ICND prefix**: The "D" in ICND stands for an improved/digital version, not a package code. - **Channel count from part number**: The last 2-3 digits sometimes indicate channel count (2024 = 24ch, 2012 = 12ch), but this is not universal. - **Tape and reel**: -TR suffix indicates tape and reel packaging, should be stripped before package extraction. <!-- Add new learnings above this line -->
