## Summary of the STMicroelectronics LRIS2K Datasheet:

This document is a datasheet for the STMicroelectronics LRIS2K Vicinity Integrated Circuit Card (VICC), a contactless RFID chip. Here's a breakdown of the key information:

Core Functionality:

️· Contactless RFID: The LRIS2K operates as a contactless RFID tag, utilizing radio frequency identification for data transmission.
️· Memory: Contains memory for user data, a unique identifier (UID), and configuration settings (AFI, DSFID).
️· Commands: Supports a wide range of commands for inventory, reading, writing, locking blocks, and controlling tag behavior (including a "Kill" command for deactivation).

Key Features & Specifications:

️· Memory Organization: Includes user area, UID block, and blocks for AFI, DSFID, Kill code, and password codes.
️· Security: Allows for locking of memory blocks and password protection.
️· Anti-Collision: Supports anti-collision algorithms for identifying and communicating with multiple tags in a field. (Inventory and Inventory Initiated commands)
️· Communication: Uses Reader Talk First (RTF) communication protocol.
️· Applications: Designed for applications requiring short-range contactless identification and data exchange (e.g., access control, item tracking).

Ordering Information:

️· Available in various package options including unsawn wafers, bumped & sawn wafers, and tape & reel with copper antennas.

Important Notes:

️· The datasheet provides a comprehensive list of commands and memory organization.
️· Includes standard disclaimers regarding product liability and intended use.
️· The chip is targeted for applications that do not include life-critical or safety-critical systems.
