The YCS X-13PM EEPROM Read / Write Composite Chip is a professional integrated programmer designed for testing and repairing baseband logic on iPhone X through 13 Pro Max series devices. This 17-in-1 tool allows technicians to read and write EEPROM data for both Intel and Qualcomm baseband chips without desoldering them from the motherboard .

The "composite chip" designation indicates that this tool integrates multiple chip programming functions into a single device, eliminating the need for separate programmers for different iPhone regional variants .

Key Features

• 17-in-1 Integrated Programming – Supports EEPROM read/write for iPhone X, XS, XS Max, 11 series, 12 series, and 13 series (including Pro, Pro Max, and Mini variants) in a single device 
• Intel & Qualcomm Chip Support – Compatible with both Intel and Qualcomm baseband chip variants found across different iPhone models and regional versions 
• No Desoldering Required – Read and write baseband EEPROM chips while they remain on the motherboard, eliminating the risk of damaging delicate components during removal and reballing 
• Integrated Display – Built-in screen allows easy monitoring of read/write operations, voltage, and current status during programming tasks 
• Short Circuit Protection – Real-time monitoring of operational parameters with short circuit alarm protection to prevent device or chip damage 
• Data Protection Mechanism – Built-in intelligent safety features prevent data loss and device damage during programming operations
