EM4022 - Multi Frequency Contactless Identification Device Anti-Collision compatible

Download the EM4022 datasheet PDF. This datasheet also covers the EM4022_EMMicroelectronic variant, as both devices belong to the same multi frequency contactless identification device anti-collision compatible family and are provided as variant models within a single manufacturer datasheet.

General Description

The EM4022 (previously named P4022) chip implements patented anti-collision protocols for both high frequency and low frequency applications.

It is even possible to identify transponders with identical codes, thereby making it possible to count identical items.

Key Features

  • Implements all BTG anti-collision protocols: Fast SWITCH-OFF, SLOW-DOWN, and FREE-.

EM MICROELECTRONIC - MARIN SA www.DataSheet4U.com EM4022 Multi Frequency Contactless Identification Device Anti-Collision compatible with BTG's Supertag Category Protocols Description The EM4022 (previously named P4022) chip implements patented anti-collision protocols for both high frequency and low frequency applications. It is even possible to identify transponders with identical codes, thereby making it possible to count identical items. The chip is typically used in “passive” transponder applications, i.e. it does not require a battery power source. Instead, it is powered up by an electromagnetic energy field or beam transmitted by the reader, which is received and rectified to generate a supply voltage for the chip.
