Description  
Pin Assignment  
The V4070 is a CMOS integrated circuit intended for  
use in electronic Read/Write RF Transponders. The  
chip contains an implementation of a crypto-algorithm  
with 96 Bits of user configurable secret-key contained  
in EEPROM. It also provides a unique Device Identi-  
fication of 32 Bits that can never be modified as well  
as 30 Bits of freely programmable USER-MEMORY.  
Bits 15 and 14 of word 1 are used as Lock-Bits. The  
memory can only be accessed for writing or erasing if  
these two bits have the contents «10» as when they  
are delivered.

COIL 2  
V4070  
The V4070 transmits data to the transceiver by modu-  
lating the amplitude of the electromagnetic field, and  
receives data and commands in a similar way.  
The coil of the tuned circuit is the only external com-  
ponent required, all remaining functions are integrated  
in the chip.
