T5557 Datasheet (Atmel) - Multifunctional 330-bit Read/Write RF-Identification IC

T5557, Multifunctional 330-bit Read/Write RF-Identification IC

The T5557 is a contactless R/W IDentification IC (IDIC®) for applications in the 125 kHz frequency range.

A single coil, connected to the chip, serves as the IC’s power supply and bi-directional communication interface.

The antenna and chip together form a transponder or tag.
