1.0.Introduction

The ACR101I SIMicro (CCID) is more than just your ordinary SIM-sized smart card reader. With the

combination of a smart card reader and a Micro SD card slot in a compact USB token, ACR101I

SIMicro (CCID) provides you with complete support for highly secured mobile applications.

Furthermore, it has an embedded MIFARE® Classic (1K) chip that allows the device to be used for

contactless applications such as logical and physical access. ACR101I SIMicro (CCID) is also

available in HID, bringing you the same plug-and-play convenience, which does not require any

special driver installation.

1.1. SIM-sized Smart Card Reader

ACR101I SIMicro (CCID) is a compact and powerful reader with its

reliable support for ISO 7816 microprocessor smart cards. It works

with most memory cards and microprocessor cards with the T=0

and T=1 protocol.

With security as its top priority, the ACR101I SIMicro (CCID) gives

you the option to integrate highly secured technologies, such as

PKI (Public Key Infrastructure), into your applications for maximum

protection of sensitive data.

1.2. Memory Storage Device

Aside from being a SIM-sized smart card reader, ACR101I SIMicro (CCID) is also a storage device.

With a dimension of 72.0 mm × 26.0 mm × 11.7 mm, this USB-powered device can be brought

anywhere and used without any cable. The ACR101I SIMicro (CCID) is also capable of supporting up

to 8 GB expandable Micro SD memory.

1.3. Contactless Feature

The ACR101I SIMicro (CCID) has an embedded MIFARE Classic 1K chip which enables it to act as a

contactless card. Its contactless attribute allows flexibility in using this powerful device in a wide array

of applications, such as physical and logical access control.

1.4. Ease of Integration

With ACR101I SIMicro (CCID) being compliant with the (CCID) Chip/Smart Card Interface Devices

and PC/SC standards, it is easier to integrate in a computer-based environment by eliminating driver

installation prior to use. In addition, ACR101I SIMicro (CCID) may now be used on mobile devices

running the Android™ platform with versions 3.1 and above.

With its wide array of features, ACR101I SIMicro (CCID) can be used in various application areas,

such as Public Key Infrastructure, network security and GSM management.

3.0.System Block Diagram

The USB Hub Controller is the communication interface between the personal computer and the MCU

of the smart card and flash memory via USB port connection. The 1 GB flash memory is available for

the end-user to use as storage. In Windows Explorer, the device is detected as a removable disk. The

ACR101 (CCID) is powered from the USB port without other external power supply.

4.0.Power Supply

The ACR101 (CCID) requires a voltage of 5 V DC, 100 mA regulated power supply. It gets the power

supply from the personal computer.

4.1. Status LED

Bicolor LED on the front of the reader indicates the activation status of the smart card and flash

memory interface.

GREEN LED:

Flashing slowly (turns on 200ms 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 power supply to the smart card is switched on, i.e., the smart card is activated.

RED LED:

Lighting up

Indicates a communication between ACR101 (CCID) and flash memory.

5.0.Smart Card Interface

The interface between the ACR101 (CCID) 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 ACR101 (CCID). The electrical specifications of this contact are identical

to those of the signal RST (at contact C2).

5.3. Card Type Selection

The controlling computer has to always select the card type, through the proper command sent to the

ACR101 (CCID) 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 an 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 ACR101 (CCID) 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 ACR101 (CCID)

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 ACR101 (CCID) never switches on the power supply to the inserted card by itself. This

must be done by the controlling computer through the proper command sent to the reader.

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

ACR101 (CCID) interfaces with the host via USB connection. It is a compounded device consisting of

two interfaces: Chip Card Interface Device and Mass Storage.

The ACR101 (CCID) 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. CCID covers all the protocols required for operating smart cards and PIN.

Note: The command for this will be discussed later on.

The configurations and usage of USB endpoints on ACR101 (CCID) 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)
