(1 PC) E5550F-S8, Temic, Standard Read/Write Identification IC
Tax included.
This listing is for 1 integrated circuit.
The e5550 is a contactless R/W-IDentification IC
(IDIC)* for general-purpose applications in the 125 kHz
range. A single coil, connected to the chip, serves as the
IC’s power supply and bidirectional communication
interface. Coil and chip together form a transponder.
The on-chip 264 bit EEPROM (8 blocks 33 bits each) can
be read and written blockwise from a Base station. The
blocks can be protected against overwriting. One block is
reserved for setting the operation modes of the IC.
Another block can contain a password to prevent
unauthorized writing.
Reading occurs by damping the coil by an internal load.
There are different bitrates and encoding schemes
possible. Writing occurs by interrupting the RF field in a
special way
