13.56 MHz 64 Data bit Read Only Contactless
Identification Device
Description
The EM4006 (previously named H4006) is a CMOS
integrated circuit intended for use in electronic Read Only
transponders.
The exited coil connected to the device generates the
power supply via a rectifier and an integrated decoupling
capacitor. The clock used for the logic is also extracted
from the coil. The logic is mainly composed by a miller
code generator and the LROM control. The memory is
factory programmed so that each IC is unique.
