RC-S620/U Product Specifications

2.9 RF Performance and the Use of Magnetic and Metal Sheets

• RF (communication) performance is closely related to the effectiveness of the magnetic and metal sheets used below and

around the antenna of the module.

• RF performance varies considerably, depending not only on the magnetic permeability (μ’, μ”), dimensions and thickness

of the magnetic sheet but also on the dimensions and material of the metal sheet used. There is also a possibility that it is

affected by metal in the installation environment.

• The module is designed to be used with the specified magnetic and metal sheets attached in advance to control the

magnetic eld generated by the antenna, as well as to minimize the possible effects from the installation environment.

This contributes a great deal to the reduction of the time required for weighing the effects of the installation environment

and evaluating the module’s RF performance.

RC-S620/U Product Specifications

3. Software Specifications

3.1 Communication Packet

The host packet format denes three types of frames – normal, extended and ACK.

Transactions between the host controller and the module are based on packet communication using host packets. The

module processes the received host command packet and returns a host response packet. Needless to say, the module cannot

autonomously transmit host response packets.

3.1.1 Normal Frame

Between the host controller and the module, the normal frame allows transmission and reception of host command/host

response packets whose LEN value is smaller than 255 bytes. This frame also provides a subordinate error frame used by

the module to notify the host controller of syntax error detection.

Table 3-1: Normal Frame

the sum of LEN and LCS bytes).

Specify the checksum of data in a packet (a value that sets 00h to the lower 1

byte of the sum of data and DCS bytes).



RC-S620/U Product Specifications

3.1.2 Extended Frame

The extended frame is used to send and receive host command/host response packets whose LEN value is greater than 256

bytes and smaller than 265 bytes.

Table 3-2: Extended Frame

Designation Size (Bytes) Remarks

Preamble 1 00h xed

Postamble

1 00h xed

Specify the data length (max. 265 bytes) in the big endian format. All data

greater than 266 bytes is interpreted as 265 bytes.
Specify the checksum of LEN data (a value that sets 00h to the lower 1 byte of

the sum of 2-byte LEN and 1-byte LCS).

Specify the checksum of data in a packet (a value that sets 00h to the lower 1

byte of the sum of data and DCS bytes).

Which type of frame is to be used for the host response packet is automatically determined – the normal frame if the LEN

value is below 255 bytes and the extended frame if it is over 256 bytes.

3.1.3 ACK Frame

The ACK frame is intended for use in the following situations.

• Module to Host Controller Transmission

- Informing the host controller that no data link level error is detected in the received host command packet.

* This is the one and only instance the module transmits the ACK frame.

• Host Controller to Module Transmission

- Interrupting host command execution.

- Determining the results on command execution (prerequisite with the Reset command). For more information, refer to

the “RC-S956 Series Command Reference Manual”.

* In the cases other than those above, the module ignores the ACK frame received from the host controller.

3.2 Communication Protocol

The communication protocol consists of a data link level and an application level.

3.2.1 Data Link Level

The modu le uses this level to make sure that the host packet is transmitted or received in accordance w ith the

communication protocol, i.e., without any error. For this purpose, the module veries the following information contained

in each host packet.

Host Command Packet

If the host command packet is veried, the module prepares an ACK frame within 3.5 ms. Stated the other way round, the

module requires a maximum of 3.5 ms in order to be ready to transmit an ACK packet after receiving an IN packet.

Acknowledging packet reception, the module proceeds to host command processing, returns a host response packet, and

waits for the reception of the next host command packet. Accordingly, it is not necessary for the host controller to be

concerned with the time interval between the reception of a host response packet and the transmission of the next host

command packet. Upon detection of a host response packet from the module, the controller optionally transmits an ACK

frame to the module.

B) If a data link level error is detected, the module remains non-responsive to the host controller. Seeing that no ACK frame

is returned, the host controller retransmits a host command packet to recover communication.

Fig. 3-2: Data Link Level Error in Host Command Packet

Major errors encountered during data link level communication are listed below.

1. Start of Packet Error

The second byte of the host command packet is not 00h, or the third byte is not ffh.

2. LCS Error

The lower 1 byte of the sum of LEN and LCS is not 00h.

3. DCS Error

The lower 1 byte of the sum obtained by adding up all data bytes and DCS is not 00h.

4. Postamble Error

The postamble byte is not included.



RC-S620/U Product Specifications

3.2.2 Application Level

This is the level where the module executes the host command specied in the host command packet.

A) When command processing is complete, the module returns a host response packet to the controller.

B) The host controller transmits an ACK frame when it is necessary to interrupt command execution by the module. The

next host command cannot be sent until more than 1 ms elapses from the interruption of host command execution (or the

completion of ACK frame transmission).

• In addition to when an ACK frame is received, the module discontinues host command processing if one of the

following factors is detected. Thereafter, it reacts by performing necessary processing, depending on the detected

factor.

- Reception of a standard USB request (Necessary processing: Responding to the request)

- USB RESET

- USB IDLE of more than 3 ms duration (Necessary processing: Suspending USB communication)

- Reception of a packet bulk-transferred (OUT direction) from Endpoint 4

C) If a syntax error is detected in the received packet, the module noties the controller by returning an error frame.

3.3 Mode Transition

3.3.1 Concept of Operating Mode

The module operates in four modes – Mode 0, Mode 1, Mode 5 and Mode 6. Available commands vary according to the

mode, while the mode changes as the result of host command execution or RF command reception. For more details, refer

to the “RC-S956 Series Command Reference Manual”.

3.3.2 Overview of Individual Modes

[a] Mode 0

[Initial Mode]

Used to perform the following functions.

• Self diagnosis

• Transfer speed setting for host communication

• RF waveform test

• Various settings for RF communication

• Starting up as an initiator or a target

In Mode 0, the module exists neither as an initiator nor a target. Switching between the initiator and target states cannot be

performed without traversing this mode.

[b] Mode 

[Target Initial State]

Enables the module to operate as a target to wait for RF command packets.

In other words, this is the mode where the TgInitTarget command is executed. Mode 5 is entered as soon as the command

execution is normally completed. Reception of a new host command packet terminates and disables the ongoing

TgInitTarget command processing and causes transition to Mode 0 for processing of the newly received host command

packet.

[c] Mode 

[Target State]

The module operates and communicates as a target.

[d] Mode 

[Initiator Operation]

The module operates and communicates as an initiator.

5. Precautions

5.1 Handling Precautions

The module must be handled with special care, keeping the following precautions in mind.

• This module is an inductive-type read/write communication device that is type-certied in compliance with the Radio Law

of Japan. The operating frequency is 13.56 MHz. Disassembly or modication of the module, removal of the type number

or similar acts are subject to penalties according to applicable laws.

• Be sure to use a stable power supply so that the module can be protected from the effect of noise and excessive voltage

peaks, such as lightning, transmitted through the power supply connector.

• Do not cause any chemical or physical damage to the module.

• Do not subject the module surface to contaminated air or materials.

• Ground all jigs, machines, workbenches and workers’ bodies to prevent static electricity from affecting the module.

• For safety’s sake, be sure to wear gloves when handling the module, although its surfaces are carefully nished.

• Protect the module from interference from other wireless machines.

• Do not install the module in an environment where a strong electromagnetic field may exert deleterious effects on

communication performance. Take special note of the installation location so that interference between the module and

other equipment can be adequately controlled.

• Communication performance may be affected by the harmonics of the 13.56 MHz carrier frequency generated on the

signal line.

• Check in advance the compatibility between the module and your system. The module cannot handle part of the

processing sequences* provided by mobile phones and other portable devices incorporating mobile FeliCa IC chips.

• The interface cable (FFC/FPC) is not supplied, making it necessary to prepare the one appropriate for your system. When

selecting the cable, make sure of the contact point direction because the module uses a single-sided interface connector.

• Measures for static noise and power line noise must be designed and incorporated on your own.

* Among the processing sequences unique to mobile FeliCa compatible portable devices, the module cannot handle the sequence which

allows wireless communication from the Reader/Writer after the mobile FeliCa IC chip was activated by the portable device via a

wired interface. For more information, refer to the “Mobile FeliCa Technical Information” (Japanese only) that explains Reader/Writer

operation in mobile applications.

Appendix Installation Requirements

The following describes the points to remember when installing the modules.

1. Do not use any metal or carbon compound as the material for the palm rest. The palm rest surface must be at least 1.5

mm apart from the board surface.

2. Do not place any metal in the forbidden zone (dot-meshed area in Fig. A-1) secured around the module. Particularly,

communication performance undoubtedly deteriorates if a plate-like metal is put near the module.

3. In order not to induce eddy current, make a cut in the metal plate surrounding the above forbidden zone.

4. If no performance improvement is achieved through the steps described above, add magnetic sheets, as shown in Fig.

A-2, to the metal surface that faces the card.

* Deviation from the resonance point caused by bringing the card closer

to the metal plate may result in a change in the card's original characteristics.

* The effect of the metal plate is reduced by adding magnetic

sheets to the positions illustrated above.

Glossary

(In alphabetical Order)

ACK

Abbreviation for ACKnowledgement, which means an afrmative message transmitted when, for example, data transfer is

successfully completed.

ASK

ASK stands for Amplitude Shift Keying. The amplitude of the carrier frequency is modulated according to the logic of the

data to be transmitted.

The degree of modulation (normally indicated in percent) is expressed by (a - b)/(a + b), where a and b respectively

represent the maximum and minimum amplitudes of the modulated signal waveform.

DCS

Abbreviation for packet Data CheckSum representing the checksum for packet data.

Initiator

A device that initiates RF communication transactions by issuing the first RF command packet. Equivalent to the

conventional FeliCa Reader/Writer.

LCS

Abbreviation for packet Length CheckSum representing the checksum for all data bytes specied by the LEN byte.

LEN

Abbreviation for packet LENgth, indicating the number of data bytes contained in the packet.

Manchester Encoding

A method of coding bit data. The bit duration time is divided at the transition point in the center and translated into two

logical values.

Target

A device that returns an RF response packet to the RF command received from the initiator in RF communications.

Equivalent to the conventional card. During Ad-hoc transactions (possible with the use of devices operating on the Mobile

FeliCa OS Version 2.0), there is a case where the target sends a command to the initiator.
