1.0.Introduction

ACR100I SIMFlash II (CCID) is not an ordinary smart card reader. Its memory storage comes with

NAND Flash memory for high capacity data storage needs. This can be partitioned into a maximum of

three sections as desired by the user. ACR100I SIMFlash II (CCID) also has an embedded Mifare 1K

chip for various contactless card functions, such as logical and physical access.

The flash memory acts like any combination of up to three drives, which may include Private/Security,

Public and CD ROM/Auto-Run, and Hidden, in order to boost security and flexibility when you store

different kinds of software. Aside from its mass storage device class compatibility, its CCID

compliance eliminates driver installation issues, allowing for its easy integration into a PC

environment.

ACR100I SIMFlash II (CCID) is designed to access SIM-sized smart cards. It can be used in E-

Government, E-Banking and E-Payment, Public Key Infrastructure, Network Security, GSM

Management, VoIP, Secure Data Storage, Access Control, and Loyalty Program.

3.0. System Block Diagram

The USB Hub Controller is the communication interface between the PC and the MCU of the smart

card and the flash memory via USB port connection. The flash memory is available for the end-user to

use as storage. In Windows Explorer, the device is detected as a removable disk. The ACR100I is

powered from the USB port without other external power supply.

4.0. Power Supply

The ACR100I requires a voltage of 5 V DC, 300 mA regulated power supply, and gets the power

supply from 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 that the ACR100I 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.

Flashing quickly

Indicates there is a communication between ACR100I and smart card.

RED LED:

Lighting up

Indicates there is a communication between ACR100I and flash memory.

4.2. Embedded Mifare Chip

The ACR100I has an embedded Mifare chip with a memory size of 1K.

5.0. Smart Card Interface

The interface between the ACR100I 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 ACR100I. The electrical specifications of this contact are identical to those

of the single RST (at contact C2).

5.3. Card Type Selection

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

ACR100I 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 ACR100I 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 ACR100I and are

immediately deactivated when the card is being removed. As a rule, however, to avoid any electrical

damage, a card should only be removed from the reader while it is powered down.

Note: The ACR100I never switches on the power supply to the inserted card by itself. This

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

the reader.

7.0. Communication Protocol

ACR100I shall interface with the host with through USB connection. A specification, namely CCID,

has been released within the industry defining such protocol for the USB chip-card interface devices.

CCID covers all the protocols required for operating smart cards and PIN.

The configurations and usage of USB endpoints on ACR100I shall follow CCID Section 3. An

overview is summarized below:

1. Control Commands are sent on a 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 ACR100I 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 ACR100I have to be

sent synchronously. (i.e. bMaxCCIDBusySlots is equal to 1 for ACR100I)

The supported CCID features by ACR100I are indicated in its Class Descriptor:
