The RC-S620/U (hereinafter called the module) writes and reads data to and from FeliCa-enabled contactless IC cards. It
can also write and read data based on the ISO/IEC 14443 communication standards. Immune to wear caused by dirt and
friction, contactless operation leads to enhanced maintainability. Key functions and features of the module are detailed
below.
• Based on an inductive read/write system type-certied by the Radio Law of Japan.
• Environmentally friendly, with the adoption of lead-free soldering.
• Compatible with devices such as mobile phones incorporating a Mobile FeliCa IC chip.
* Not all of the processing sequences can be handled.
• Compactly designed with an integral antenna.
• Requires the use of specied magnetic and metal sheets.
• Interface versatility made possible by the use of USB for host controller connection.
• Successful passage of rigorous validation tests by Microsoft’s WHQL (Windows Hardware Quality Labs).

2. Hardware Specifications
This chapter focuses on major hardware specications.
2.1 Major Specifications
The following describes the module’s major specications.
2.1.1 FeliCa Communication
Max. communication distance : Approx. 20 mm
* Measurement conditions
In a free space (temperature: 25°C, humidity: 50% RH) that is potentially
The card is placed so that its center aligns with the center of the module’
* The communication distance varies depending on the usage environment.
(No dead zones of more than 1 mm wide within the max. communication
distance)
unaffected by nearby radio waves and magnetic sources, a single RC-S880
card (operating at its center frequency) is polled by a standard module.
s antenna along a vertical axis perpendicular to the antenna surface, with its
longitudinal edges maintained in parallel to those of the antenna. (See Fig.
2-1.)
Carrier frequency : 13.56 MHz
Data transfer rate : 212 kbps,424 kbps (available only when the card or the device to be
used is also compatible with 424 kbps.)
Modulation system : Transmission – ASK
Reception – ASK
Bit coding : Transmission – Manchester coding
Reception – Manchester coding
Communication system : Half-duplex communication, CRC-ITU-T
Compatible cards
FeliCa cards : RC-S860 Series (RC-S860, RC-S862, RC-S864)
RC-S880 Series
RC-S850 Series (RC-S850, RC-S853, RC-S854, RC-S855)
Compatible devices : Mobile phones incorporating a Mobile FeliCa IC chip

Antenna of the Module
*The relative positions of the card and the antenna are determined
first by paralleling their longitudinal directions and second, by
aligning their centers along an axis that intersects at right angles
with the antenna.
<Note>
Please consult us in advance when using a card or a device other than the ones listed above. Such a card or device
may differ in communication distance, making it necessary to verify its performance.
• Ad-hoc Communication
Data transfer rate : Initiator mode 212 kbps,424 kbps (available only when the card or
the device to be used is also compatible with 424 kbps.)
Target mode 212 kbps
Compatible devices : Mobile phones with a built-in Mobile FeliCa IC chip (on which the
Mobile FeliCa OS Version 2.0 is running)
* Feasibility of data exchange and other functions necessary for application execution depends on the FeliCa Ad-
hoc Link Protocol (FALP) on the device used to control the module and mobile phones, as well as the method
of implementing the FALP-compatible application. For more information, please refer to the documents that
accompany Sony’s software development kit and individual applications.
