EM4205,EM4305

Overview

EM4205/EM4305 is one of the most common low frequency chip, which has many applications such as Animal Identification according to ISO FDX-B,Pigeon races standard,Waste management standard(BDE),ACCESS Control,Industrial etc….

General Description:

EM4205/4305 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders. It is suitable for low cost solutions like animal tagging applications. The IC communication protocol is compatible with the EM4469/4569 family.The main difference between the EM4205 and EM4305 is that:
- EM4305 are bumped with enlarged pads for the two coil inputs. The enlarged bumped pads of the EM4305 transponder are intended for direct antenna connection avoiding the need of a module.
- EM4305 offers a 330pF resonant capacitor version.
