DS2501 - 512-Bit Add-Only Memory

Datasheet Summary

Description

The DS2501 512-bit add-only memory identifies and stores relevant information about the product to which it is associated.

This lot- or product-specific information can be accessed with minimal interfacefor example, a single port pin of a microcontroller.

Features

512 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground.
Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48bit serial number + 8-bit CRC tester) assures absolute traceability because no two parts are alike.
Built-in multidrop controller ensures compatibility with other MicroLAN products.
EPROM partitioned into two 256-bit pages for randomly accessing packetized data.
Each memo.
