1.0.Introduction
More than just a smart card reader, the ACR100F (CCID) SIMFlash has a built-in flash memory and is
designed for both accessing plug-in (SIM-sized) smart cards and for data or application storage. It is
ideal for GSM solutions such as GSM management software and VoIP applications, electronic
payment systems, e-commerce, home banking, transportation, and computer and network access.
The flash memory acts like any combination of up to three drivers, which may include public, private,
CD-ROM (optional autorun area) and hidden drives, in order to boost security and flexibility when you
store different kinds of software. Aside from its Mass Storage Device Class compatibility, its plug and
play feature is enhanced with its smart card reader now CCID compliant, reducing driver installation
issues.

4.0.Power Supply
The ACR100F requires a voltage of 5 V DC, 100 mA regulated power supply. It gets the power supply
from the PC.
4.1. Status LED
Bicolor LED in front of the reader indicates the activation status of the smart card and flash memory
interface.
GREEN LED:
Flashing slowly (turns on 200 ms for every 2 seconds)
Indicates smart card interface part is powered up and in the standby state. Either the smart
card has not been inserted or the smart card has not been powered up (if it is inserted).
Lighting up
Indicates the smart card power is switched on, i.e., the smart card is activated.
RED LED:
Lighting up
Indicates a communication between ACR100F and flash memory.

5.0.Smart Card Interface
The interface between the ACR100F and the inserted smart card follows the specifications of ISO
7816-3.
5.1. Smart Card Power Supply VCC (C1)
The current consumption of the inserted card must not be higher than 50 mA.
5.2. Programming Voltage VPP (C6)
According to ISO 7816-3, the smart card contact C6 (VPP) supplies the programming voltage to the
smart card. Since all common smart cards in the market are EEPROM based and do not require the
provision of an external programming voltage, the contact C6 (VPP) has been implemented as a
normal control signal in the ACR100F. The electrical specifications of this contact are identical to
those of the signal RST (at contact C2).
5.3. Card Type Selection
The controlling PC has to always select the card type through the proper command sent to the
ACR100F prior to activating the inserted card. This includes both the memory cards and MCU-based
cards. For MCU-based cards, the reader allows to select the preferred protocol, T=0 or T=1, however,
this selection is only accepted and carried out by the reader through the PPS when the card inserted
in the reader supports both protocol types. Whenever a MCU-based card supports only one protocol
type, T=0 or T=1, the reader automatically uses that protocol type, regardless of the protocol type
selected by the application.
5.4. Interface for Microcontroller-Based Cards
For microcontroller-based smart cards, only the contacts C1 (VCC), C2 (RST), C3 (CLK), C5 (GND)
and C7 (I/O) are used. A frequency of 4 MHz is applied to the CLK signal (C3).
5.5. Card Tearing Protection
The ACR100F provides a mechanism to protect the inserted card when it is suddenly withdrawn while
it is powered up. The power supply to the card and the signal lines between the ACR100F and the
card are immediately deactivated when the card is being removed. As a general rule, however, to
avoid any electrical damage, a card should only be removed from the reader while it is powered
down.
Note: The ACR100F never switches on the power supply to the inserted card by itself. This
must explicitly be done by the controlling computer through the proper command sent to the
reader.

6.0.USB Interface
The connection of the ACR100F to a computer through a USB port follows a USB Standard.
6.1. Communication Parameters
The ACR100F is connected to a computer through USB as specified in the USB Specification. The
ACR100F is working in high-speed mode, i.e. 480 Mbps, for the flash memory and USB 1.1 full-speed
mode for smart card interface.
Pin Signal Function
1 VBUS +5 V power supply for the reader
2 D- Differential signal transmits data between ACR100F and PC.
3 D+ Differential signal transmits data between ACR100F and PC.
4 GND Reference voltage level for power supply
6.2. Endpoints
The ACR100F uses the following endpoints to communicate with the host computer:
Control Endpoint 0 For setup and control purposes
Bulk OUT Endpoint 1 For the command to be sent from host to Mass Storage Interface
(data packet size is 64 bytes)
Bulk IN Endpoint 1 For response to be sent from Mass Storage Interface to host (data
packet size is 64 bytes)
Bulk OUT Endpoint 2 For command to be sent from host to CCID Interface (data packet
size is 16 bytes)
Bulk IN Endpoint 2 For response to be sent from CCID Interface to host (data packet
size is 16 bytes)

7.0.Communication Protocol
ACR100F interfaces with the host via USB connection. It is a compounded device consisting of two
interfaces: Chip Card Interface Device and Mass Storage.
The ACR100F Smart Card Interface shares the same core as the smart card interface of the ACR38
CCID. The Smart Card Interface will be identified as “ACR38-112c” once the reader FW is obtained.
(The command for this will be discussed later on). CCID covers all the protocols required for operating
smart cards and PIN.
The configurations and usage of USB endpoints on ACR100F Smart Card Interface shall follow CCID
Section 3. An overview is summarized below:
1. Control Commands are sent on control pipe (default pipe). These include class-specific
requests and USB standard requests. Commands that are sent on the default pipe report
information back to the host on the default pipe.
2. CCID Events are sent on the interrupt pipe.
3. CCID Commands are sent on BULK-OUT endpoint. Each command sent to smart card
reader has an associated ending response. Some commands can also have intermediate
responses.
4. CCID Responses are sent on BULK-IN endpoint. All commands sent to the smart card reader
have to be sent synchronously. (i.e. bMaxCCIDBusySlots is equal to 1)
The supported CCID features by ACR100F smart card interface are indicated in its Class Descriptor:

7.1. Command to the ACR100F (CCID)
In the normal operation, the ACR100F acts as a slave device with regard to the communication
between a computer and the reader. The communication is carried out in the form of successive
command-response exchanges. The computer transmits a command to the reader and receives a
response from the reader after the command has been executed. A new command can be transmitted
to the ACR100F only after the response to the previous command has been received.
There are two cases where the reader transmits data without having received a command from the
computer, namely, the Reset Message of the reader and the Card Status Message.
7.1.1. CCID Command Pipe Bulk-OUT Messages
The ACR100F shall follow the CCID Bulk-OUT Messages as specified in CCID section 4. In addition,
this specification defines some extended commands for operating additional features. This section
lists the CCID Bulk-OUT Messages to be supported by ACR100F.

C_SEL The currently selected card type. A value of 00Hmeans that no card type has been
selected.
C_STAT Indicates whether a card is physically inserted in the reader and whether the card is
powered up:
00H: no card inserted
01H: card inserted, not powered up
03H: card powered up
7.2. Mass Storage
Mass Storage Device Class specifies all the protocols required for data transaction between the Host
(computer) and storage devices. The configurations and usage of USB endpoints on ACR100 shall
follow Mass Storage Class Bulk-Only Transport in Section 3 (Protocol Code) of the USB Mass
Storage Device Specification. This document is available at: www.usb.org.
An overview of this specification is summarized below:
1. Control Commands are sent on control pipe (default pipe). It is shared with the CCID
interface.
2. Data-Out Command Protocol uses the BULK-OUT endpoint to transfer data from the host to
the device.
3. Data-In Command Protocol uses the BULK-IN endpoint to transfer data from the device or to
return status about the device.
