AT90RF135602
Description
AT90RF135602 is an ultra small footprint low-cost Radio Frequency Identification
(RFID) reader developed with Innovision Research & Technology plc to address
multi-protocol 13.56 MHz RFID applications.
It is optimised for use with the established ISO/IEC14443 type A standard and is avail-
able in Low-profile Ball Grid Array (LBGA).
The LBGA incorporates a custom transceiver front-end along with a protocol & com-
munications controller. It requires only an external crystal and minimal external
passive components to interface to the reader antenna.
Protocols are software defined and hence configurable.
