A hyphen is encountered 2. Letters and digits have both been found, and a non-alphanumeric appears --- ## Snapdragon Naming Evolution ### Modern Naming (2021+) | Series | Tier | Examples | |--------|------|----------| | SM8xxx | Flagship (8-series) | SM8550 (Gen 2), SM8650 (Gen 3) | | SM7xxx | Premium (7-series) | SM7550, SM7450 | | SM6xxx | Mainstream (6-series) | SM6350, SM6225 | | SM4xxx | Budget (4-series) | SM4350, SM4250 | ### Legacy Naming | Series | Year | Examples | |--------|------|----------| | SD8xx | 2017-2021 | SD888, SD865, SD855, SD845 | | SD7xx | 2018-2021 | SD780, SD765, SD750 | | SD6xx | 2017-2021 | SD695, SD680, SD660 | | SD4xx | 2016-2021 | SD480, SD460, SD450 | | MSM89xx | 2014-2017 | MSM8996, MSM8953 | ### Performance Tiers (Suffix Keywords) | Tier | Keyword | Description | |------|---------|-------------| | Elite | Elite | Highest performance | | Plus | Plus | Enhanced variant | | Pro | Pro | Professional variant | | Standard | (none) | Base variant | ### Generation (Suffix Keywords) | Generation | Keyword | Year | |------------|---------|------| | Gen 1 | Gen1 | 2021 | | Gen 2 | Gen2 | 2022 | | Gen 3 | Gen3 | 2023 | --- ## Supported ComponentTypes The handler registers all patterns under `ComponentType.IC` and declares: ```java getSupportedTypes() → { WIFI_IC_QUALCOMM } ``` **Known Issue**: The handler registers patterns for many IC categories (SoCs, modems, PMICs, etc.) but only declares `WIFI_IC_QUALCOMM` in `getSupportedTypes()`. Consider adding `IC` to `getSupportedTypes()` for completeness. --- ## Replacement Compatibility Logic The handler implements sophisticated replacement checking via `isOfficialReplacement()`: ### Compatible Series Pairs | Series 1 | Series 2 | Category | |----------|----------|----------| | SD8xx | SD8xx | Snapdragon flagship | | SM8xx | SM8xx | Snapdragon mobile | | QCS4xx | QCS4xx | IoT platform | | QCM2xx | QCM2xx | IoT module | | QM4xx | QM4xx | RF module | | QCA6xx | QCA6xx | Wi-Fi/Bluetooth | | WCN3xx | WCN3xx | Wireless connectivity | ### Category-Specific Checks **Snapdragon SoCs** (SM, SD, QSD, MSM): - Generation compatibility (higher gen can replace lower) - Performance tier compatibility (Elite > Plus > Pro > Standard) **Wireless Modules** (QCA, WCN, MDM, FSM): - Wi-Fi version compatibility (WiFi-6 > WiFi-5 > WiFi-4) - Bluetooth version compatibility (5.2 > 5.1 > 5.0 > 4.2) **Power Management** (PM, PMI, SMB): - Voltage rating compatibility (within 5% tolerance) - Current rating compatibility (higher can replace lower) --- ## Example MPNs ### Mobile SoCs | MPN | Description | |-----|-------------| | SM8550-AB | Snapdragon 8 Gen 2 flagship SoC | | SM8450-3-AB | Snapdragon 8 Gen 1 SoC | | SD888 | Snapdragon 888 flagship (legacy naming) | | MSM8996 | Snapdragon 820/821 SoC | | QSD8250 | First-gen Snapdragon | ### IoT Platforms | MPN | Description | |-----|-------------| | QCS603 | Vision Intelligence Platform | | QCM6490 | IoT module with 5G | | APQ8064 | Application processor (no modem) | | IPQ8074 | Networking processor for routers | ### RF Front-End | MPN | Description | |-----|-------------| | QM42195 | RF front-end module | | QPM5677 | Power amplifier module | | QAT3555 | Antenna tuner | | QET6100 | Envelope tracking module | ### Wireless Connectivity | MPN | Description | |-----|-------------| | QCA6390 | Wi-Fi 6E / Bluetooth 5.2 | | QCA6174A-3-FCBGA | Wi-Fi 5 / BT 4.2, FCBGA package | | WCN6855 | Wi-Fi 6E combo chip | | MDM9650 | LTE Cat-9 modem | ### Power Management | MPN | Description | |-----|-------------| | PM8550 | Main PMIC for SM8550 | | PMI8998 | Power management IC | | SMB1360-1-BGA | Battery charging IC, BGA package | ### Audio | MPN | Description | |-----|-------------| | WCD9380 | Audio codec | | WSA8810 | Smart speaker amplifier | --- ## Handler Implementation Notes ### Pattern Matching All patterns are registered under `ComponentType.IC`: ```java // Mobile Platforms "^SM[0-9]{3}.*" // SM8550, SM7450 "^SD[0-9]{3}.*" // SD888, SD865 "^QSD[0-9]{4}.*" // QSD8250 "^MSM[0-9]{4}.*" // MSM8996 // IoT/Embedded "^QCS[0-9]{3}.*" // QCS603 "^QCM[0-9]{3}.*" // QCM2150 "^APQ[0-9]{4}.*" // APQ8064 "^IPQ[0-9]{4}.*" // IPQ8074 // RF Front-End "^QM[0-9]{4}.*" // QM42195 "^QPM[0-9]{4}.*" // QPM5677 "^QAT[0-9]{4}.*" // QAT3555 "^QET[0-9]{4}.*" // QET6100 // Wireless "^QCA[0-9]{4}.*" // QCA6390
