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.
2.0. Features USB Combo Device – works as a smart card reader and mass storage device SIM-sized slot for smart card at USB 2.0 full speed NAND Flash support at USB 2.0 high speed Plug-and-Play – CCID support brings supreme compatibility and mobility Extractable USB Two color LEDs for smart card and NAND Flash status indication Smart card reader: o Supports plug in (SIM-sized) cards o Supports ISO 7816 Class A, B, and C (5 V, 3 V, 1.
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. Antenna for Mifare Chip Mifare Chip Smart Card USB Interface Interface Circuit SIM-sized Smart Card 2 PORT USB 2.
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).
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.
6.0. USB Interface The connection of the ACR100I to a computer through a USB port follows a USB Standard. 6.1. Communication Parameters The ACR100I is connected to a computer through USB as specified in the USB Specification 2.0. The ACR100I is working in high-speed mode, i.e. 480 Mbps. Pin Signal Function 1 VBUS +5 V power supply for the reader (Max 500 mA, Normal 300 mA) 2 D- Differential signal transmits data between ACR100I and PC.
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. overview is summarized below: An 1. Control Commands are sent on a control pipe (default pipe).
