Description
The 1QU9-0004 is a 1024-bit, 1-Wire® EEPROM chip designed for use in electronic components. It is organized into four memory pages, with each page containing 256 bits of data. The chip features a special write protection function, allowing each memory page to be individually write-protected or put in EPROM-emulation mode. The communication between the chip and the host device follows the standard 1-Wire protocol, with each chip having its own unique 64-bit ROM registration number. The 1QU9-0004 is suitable for use in multidrop, 1-Wire net environments.Specifications and features
- 1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits - Individual Memory Pages Can Be Permanently Write Protected or Put in EPROM-Emulation Mode - Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise - IEC 1000-4-2 Level 4 ESD Protection (±8kV Contact, ±15kV Air, Typical) - Reads and Writes Over a Wide Voltage Range from 2.8V to 5.25V from -40°C to +85°C - Communicates to Host with a Single Digital Signal at 15.4kbps or 125kbps Using 1-Wire Protocol - Also Available as Automotive Version Meeting AEC-Q100 Grade 1 Qualification Requirements (DS2431-A1)Application Scenarios
The 1QU9-0004 can be used in various electronic component applications where EEPROM memory is required. It is particularly suited for situations where individual memory pages need to be write-protected or put in EPROM-emulation mode. The chip's wide voltage range and temperature range make it suitable for use in various environmental conditions. Additionally, its communication protocol allows for easy integration with host devices.Comparison
Advantages- 1024 bits of EEPROM memory provides ample storage capacity - Individual memory pages can be write-protected, enhancing data security - Wide voltage range and temperature range allow for versatile usage - Integrated ESD protection ensures robust performance even in harsh conditionsDisadvantages- Limited communication speed compared to other protocols - Requires support for 1-Wire protocol in host devices - Automotive version is available but may not be suitable for all applications -
