CLRC663 Quickstart Guide

3. Hardware design of the RC663 evaluation board (“red board”)

3.1 Scope

This part describes the functionality of the evaluation reader based on the RC663. It

includes the functional and electrical specifications and gives the needed details to use

this reader as a reference design.

This reader implementation is based on the HVQFN33 package (body 5 x 5 x 0.85 mm).

The RC663 itself is described in the corresponding data sheet (see reference [1]).

3.2 Features

• Single 7.5 V external power supply

• RS232 DSUB9 connector for easy connection to a host PC

• RS232 Serial UART up to 1228.8 kBd, with voltage levels dependent on pin voltage

supply

• Supports transfer speed communication up to 848 kbit/s with credentials

• I/O pins (GPIO0/SIGIN; SIGOUT)

• Hard Power Down

• Standby mode

• Programmable and cascadable timers

• FiFo buffer handles 512 byte send and receive

• IntegerN PLL providing clock for standard microcontroller used frequencies

• Low power card detection

• Integrated Free-Running Low Power Oscillator

• Digital test signal pins CLKOUT,SIGOUT,TCK,TDI,TDO,TMS

• versatile quadrature receiver architecture with fully differential receiver

• Antenna size: 113 mm x 77 mm
