3 Description
This security RFID transponder provides an 80-bit
encryption algorithm. The 5-byte challenge and 3-
byte response algorithm is backward compatible with
existing TI products and provides, together with the
burst length coding, short encryption telegram times.
The DST80 offers 65 bytes of free programmable
user data stored in nine pages, each of them lockable
for programming. Each of the two 80-bit encryption
keys with can be programmed with a single telegram.
The DST80 comes in two versions, preprogrammed
with either PWM or PPM communication formats,
eliminating the need for the user to change this field.
For a higher security level, the DSTAES transponder
with AES-128 encryption is recommended.
