EM4100 Datasheet | EM MICROELECTRONIC

EM MICROELECTRONIC - MARIN SA Read Only Contactless Identification Device Description The EM4100 (previously named H4100) is a CMOS integrated circuit for use in electronic Read Only RF Transponders. The circuit is powered by an external coil placed in an electromagnetic field, and gets its master clock from the same field via one of the coil terminals. By turning on and off the modulation current, the chip will send back the 64 bits of information contained in a factor y preprogrammed memory array. The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code on each chip. The EM4100 has several metal options which are used to...
