EM4450/EM4550 chip cards,125KHz EM4450/EM4550 read/write
contactless identification chip cards
The EM4450 is a CMOS integrated circuit intented for use in
electronic Read/Write RF Transponders. The chip contains 1 KBit of
EEPROM which can be configured by the user, allowing a write
inhibited area, a read protected area, and a read area output
continuously at power on.
The memory can be secured by using the 32 bit password for all
write and read protected operations. The password can be updated,
but never read. The fixed code serial number and device
identification are laser programmed making every chip unique.
The EM4450 will transmit data to the transceiver by modulating the
amplitude of the electromagnetic field, and receive data and
commands in a similar way. Simple commands will enable to write
EEPROM, to update the password, to read a specific memory area, and
to reset the logic. The coil of the tuned circuit is the only
external component required, all remaining functions are integrated
in the chip.
