1.1 Product introduction

The CMC303 is a UHF RFID Reader hybrid module which integrates high performance UHF RFID
reader chipset,TCXO, Balun, Coupler, Saw filter, Power amp and low pass filter.UHF RFID reader chipset
uses PR9200 of PHYCHIPS which integrates 900MHz radio, baseband processor,industry standard enhanced
Cortex-M0 MCU, memory (64k Flash & 1 6k SRAM) and many other features. Thismodule fully compliant
with ISO18000-6C/EPC Global Gen II reader protocol and provide all functions of PR9200. Also reduce size,
cost and power consumption. The CMC303 includes automatic tx leakage cancellation to improve reader’s
performance and compensate sensitivity for some variation according to the surrounding environment. Also it
helps a developer adopt the proper antenna and realize the optimized RFID reader system more easily and
quickly.

Application:

 Management of warehousing logistics, assets, livestock, books, tickets, access control, container, etc.
 Various occasions when mobile data collection is needed

Features：

 Compliant with the EPC Class1 Gen2 (ISO18000-6C) ；
 Real-time no-leakage in ve n tor y file list, timing inventory, closing trigger inventory
 Fast positioning file storage location, so that arbitrary placement, fast search
 High reliability, aluminum out case, for the harsh work condition.
