May 2003 Multiple Protocol Contactless Reader IC 1 1.1 CL RC632 RC632 GENERAL INFORMATION Scope This document describes the functionality of the CL RC632 RC632. It includes the functional and electrical specifications and gives details on how to design-in this device from system and hardware viewpoint. 1.2 General Description The CL RC632 RC632 is member of a new family of highly integrated reader ICs for contactless communication at 13.56 MHz. This reader IC family utilises an outstanding modulation and demodulation concept completely integrated for all kinds of passive contactless communication methods and protocols at 13.56 MHz. The CL RC632 RC632 is pin- compatible to the MF RC500 RC500, the MF RC530 RC530, the MF RC531 RC531 and the SL RC 400. The CL RC632 RC632 supports all layers of the ISO14443 ISO14443 including the type A and type B communication scheme. The CL RC632 RC632 supports contactless communication using MIFARE® Higher Baudrates. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO14443 ISO14443 compatible transponders. The digital part handles the complete ISO14443 ISO14443 framing and error detection (Parity & CRC). Additionally it supports the fast MIFARE® Classic security algorithm to authenticate MIFARE Classic (e.g. MIFARE® Standard, MIFARE® Light) products. The CL RC632 RC632 supports all layers of I·CODE1 and ISO 15693. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from I·CODE1 and ISO 15693 compatible transponders. The digital part handles I·CODE1 and ISO 15693 framing and error detection (CRC). The internal transmitter part is able to drive an antenna designed for proximity operating distance (up to 100 mm) directly without additional active circuitry. A comfortable parallel interface, which can be directly connected to any 8-bit µ-Processor gives high flexibility for the reader/terminal design. Additionally a SPI compatible interface is supported. 7 Confidential Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC 1.3 CL RC632 RC632 Features · Highly integrated analog circuitry to demodulate and decode card/label response · Buffered output drivers to connect an antenna with minimum number of external components · Proximity operating distance (up to 100 mm) · Supports ISO 14443 A&B · Supports MIFARE® Dual Interface Card ICs and supports MIFARE® Classic protocol · Supports contactless communication with MIFARE® higher baudrates up to 424 kbaud · Supports I·CODE1 and ISO 15693 · Crypto1 and secure non-volatile internal key memory · Pin-compatible to the MF RC500 RC500, MF RC530 RC530, MF RC531 RC531 and the SL RC400 RC400 · Parallel µ-Processor interface with internal address latch and IRQ line · SPI compatible interface · Flexible interrupt handling · Automatic detection of parallel µ-Processor interface type · Comfortable 64 byte send and receive FIFO-buffer · Hard reset with low power function · Power down mode per software · Programmable timer · Unique serial number · User programmable start-up configuration · Bit- and byte-oriented framing · Independent power supply pins for digital, analog and transmitter part · Internal oscillator buffer to connect 13.56 MHz quartz, optimised for low phase jitter · Clock frequency filtering · 3.3 V to 5 V operation for transmitter (antenna driver) in short range and proximity applications · 3.3 V or 5V operation for the digital part 1.4 Ordering Information Type Number CL RC632 RC632 01T/0FE 01T/0FE Package Name Description SO32 Small Outline Package; 32 leads Table 1-1: CL RC632 RC632 Ordering Information 8 Confidential Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC 2 CL RC632 RC632 BLOCK DIAGRAM N_WR, N_RD, N_CS ALE A0, A1, A2 D0 to D7 FIFO Control DVDD Voltage Monitor & Power On Detect Parallel Interface Control (incl.

AD7 Table 4-1: Supported µ-Processor Interface Signals 4.2 Automatic µ-Processor Interface Type Detection After every Power-On or Hard Reset, the CL RC632 RC632 also resets its parallel µ-Processor interface mode and checks the current µ-Processor interface type. The CL RC632 RC632 identifies the µ-Processor interface by means of the logic levels on the control pins after the Reset Phase. This is done by a combination of fixed pin connections (see below) and a dedicated initialisation routine (see 11.4). 13 Confidential Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC 4.3 CL RC632 RC632 Connection to Different µ-Processor Types The connection to different µ-Processor types is shown in the following table: Parallel Interface Type Separated Read/Write Strobe Common Read/Write Strobe CL RC632 RC632 Dedicated Address Bus Multiplexed Address Bus Dedicated Address Bus Multiplexed Address Bus Multiplexed Address Bus with Handshake ALE HIGH ALE HIGH AS nAStrb A2 A2 LOW A2 LOW HIGH A1 A1 HIGH A1 HIGH HIGH A0 A0 HIGH A0 LOW nWait NRD NRD NRD NDS NDS nDStrb NWR NWR NWR R/NW R/NW nWrite NCS NCS NCS NCS NCS LOW D7 .

Remarks for EPP: Although in the standard for the EPP no chip select signal is defined, the N_CS of the CL RC632 RC632 allows inhibiting the nDStrb signal. If not used, it shall be connected to DVSS. After each Power-On or Hard Reset the nWait signal (delivered at pin A0) is high impedance. nWait will be defined at the first negative edge applied to nAStrb after the Reset Phase. The CL RC632 RC632 does not support Read Address Cycle. 16 Confidential Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC 4.4 CL RC632 RC632 SPI compatible interface Additionally the serial peripheral interface (SPI) will be supported. The CL RC632 RC632 acts as a slave during the SPI communication. The SPI clock SCK has to be generated by the master. Data communication from the master to the slave uses the line MOSI.

In principle bits with same behaviour are grouped in common registers. Abbreviation Behaviour Description read and write These bits can be written and read by the µ-Processor. Since they are used only for control means, there content is not influenced by internal state machines, e.g. the TimerReload-Register may be written and read by the µProcessor. It will also be read by internal state machines, but never changed by them. dy dynamic These bits can be written and read by the µ-Processor. Nevertheless, they may also be written automatically by internal state machines, e.g. the CommandRegister changes its value automatically after the execution of the actual command. r read only These registers hold flags, which value is determined by internal states only, e.g. the ErrorFlag-Register can not be written from external but shows internal states. write only These registers are used for control means only. They may be written by the µProcessor but can not be read. Reading these registers returns an undefined value, e.g. the TestAnaSelect-Register is used to determine the signal on pin AUX, but it is not possible to read its content. r/w w Table 5-2: Behaviour of Register Bits and its Designation 22 Confidential Philips Semiconductors Product Specification Rev. 3.0; May 2003 Multiple Protocol Contactless Reader IC 5.2 CL RC632 RC632 Register Description 5.2.1 PAGE 0: COMMAND AND STATUS 5.2.1.1 Page Register Selects the register page.
