Maxim DS2431 is a 1024-bit, 1-Wire® EEPROM chip organized as four memory pages of 256 bits each. Data is written to an 8-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, the four memory pages can individually be write protected or put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state.
Features
• Individual Memory Pages Can Be Permanently Write Protected or Put in EPROM-Emulation Mode (“Write to 0”) • 1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits • IEC 1000-4-2 Level 4 ESD Protection (±8kV Contact, ±15kV Air, Typical) • Communicates to Host with a Single Digital Signal at 15.4kbps or 125kbps Using 1-Wire Protocol • Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
Applications
• Medical Sensor Calibration Data Storage • Accessory/PCB Identification • Analog Sensor Calibration Including IEEE P1451.4 Smart Sensors • Ink and Toner Print Cartridge Identification • After-Market Management of Consumables
Note
Please note that any defect or non – conformance of this product must be discovered and reported to RS within 20 days of purchase.
