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.

Features
Figure 6. SPI Block Diagram
The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer
between the AT90RF135602 and peripheral devices or between several AVR devices.
The AT90RF135602 SPI includes the following features:
• Full-duplex, Three-wire Synchronous Data Transfer
• Master or Slave Operation
• LSB First or MSB First Data Transfer
• Seven Programmable Bit Rates
• End of Transmission Interrupt Flag
• Write Collision Flag Protection
• Wake-up from Idle Mode
• Double Speed (CK/2) Master SPI Mode
