Memory IC datasheet and documents for DS2502-E64+

DS2502-E64+

Memory IC Overview

The DS2502-E64+ is a 1-Wire EPROM device featuring a factory-programmed 64-bit IEEE EUI-64 node address and 768 bits of user-programmable OTP memory. It operates within a supply voltage range of 2.8V to 6.0V and supports programming at 11.5V to 12.0V. The component utilizes a TO-92-3 package for through-hole mounting and functions across an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

Contains a globally unique, factory-lasered 64-bit registration number ensuring absolute traceability.
Functions as add-only memory, allowing data programming without disturbing existing content.
Integrates a built-in multidrop controller for compatibility with other 1-Wire products.
Meets node identification requirements for IEEE Standard 1394-1995 (FireWire).

Memory IC Applications

IEEE 1394-1995 FireWire node identification
UniqueWare identifier implementation
1-Wire bus master system integration

Memory IC Procurement Notes

Verify the specific suffix designation when sourcing components. Confirm that the ordering suffix corresponds to the required package type, such as TO-92 or TSOC, as these physical variations do not alter the internal electrical function. Ensure compliance with lead-free specifications if required by the application environment.

Memory IC Selection Notes

Select this component when a unique hardware identifier compliant with IEEE EUI-64 standards is required. It is suitable for applications needing non-volatile storage alongside a permanent serial number. Consider the single-pin interface requirement and the specific voltage levels needed for both operation and programming.

Memory IC Part Context

This part belongs to the DS2502 family of 1-Wire Add-Only Memories. It differs from the standard DS2502 by utilizing a custom ROM family code and a UniqueWare Identifier in place of the upper 12 bits of the standard ROM serialization field. Electrical and logical behaviors remain identical to the base model.
