The GX2431Q is a 1024-bit EEPROM memory chip featuring a single bus interface. Each device contains a globally unique 64-bit serial number and supports the 1-Wire communication protocol. The 64-bit ROM address code is laser-etched during factory production to ensure absolute traceability. Data transmission follows the 1-Wire protocol, requiring only one data line and a ground return line.
Key Features
Single bus interface requiring only one port pin for communication
Globally unique 64-bit serial number for each chip
1024-bit EEPROM memory organized into four 256-bit pages
Independent memory pages with permanent write-protection or EPROM emulation mode
No peripheral components required
Data line powered with voltage range of 2.5V to 5.5V
Operating temperature range: -55℃ to +125℃
Exceptional ESD protection: HBM8000V, MM800V
Communication rates: 15.4kbps or 125kbps via 1-Wire protocol
Application Scenarios
Host accessories and PCB board card identification
Medical device parameter storage
Analog sensor calibration
Ink cartridge and toner cartridge identification
Consumer product after-sales management
BMS product parameter storage
Technical Overview
The GX2431 is a 1024-bit EEPROM that communicates with the host using the standard 1-Wire bus protocol. It features four independent 256-bit memory pages. Data is initially written to an 8-byte buffer and, after verification, copied to EEPROM memory. Memory pages can be individually configured for write protection or EPROM emulation mode, where bits can only transition from 1 to 0.
