Gamma radiation sterilization is typically used on single-use medical sensors and consumables because the method is predictable, reliable, faster to process, and usable across a wide range of product materials and packaging types. However, gamma radiation is incompatible with traditional floating-gate memory technologies used in semiconductors because the high ionizing gamma radiation erases the memory. The new DS28E80 NV memory, however, is resistant to gamma radiation up to 75 kGy (kilogray). With flexible programming options, it allows OEMs to calibrate their factory sensors, tools, and accessories for their medical instrumentation in the field. It can be used to control or even prevent the unsanitary reuse of disposable medical sensors and consumables. It works with the company's reliable 1-Wire interface, so consumable manufacturers can replace multiple cumbersome wires with a single contact.
Key Advantages
• Manufacturing Calibration: OEMs can automatically detect and calibrate sensors and accessories to ensure quality.
• Usage Tracking: Protects against incorrect placement and warns against or prevents unhygienic reuse of consumables.
• Integrated Identification: The integrated 1-Wire protocol provides a factory-preemptive, tamper-proof 64-bit serial ID that enables tracking and can prevent the use of unauthorized consumables.
• Reprogrammable: 248 bytes of user memory organized into 8-byte blocks
