1.0. Introduction The ACR101 SIMicro (CCID) is a combination of a smart card reader and a Micro-SD card slot in a compact USB token which provides you with complete support for highly secure mobile applications. Furthermore, it has an embedded Mifare chip which allows the device to be used for contactless applications such as logical and physical access.
2.0. Features USB combo device – works as smart card reader and mass storage USB 2.0 Hi-Speed Interface Bus-powered – no need for separate power supply or battery Plug–and-play – CCID support brings utmost compatibility and mobility With extractable USB cable and keychain loop Smart card reader: o Supports plug-in (SIM-sized) cards o Supports ISO 7816 Classes 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 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. Smart Card Interface Circuit USB Interface USB 2.
4.0. Power Supply The ACR101 (CCID) requires a voltage of 5V DC, 100mA regulated power supply. It gets the power supply from the PC. 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.
5.0. Smart Card Interface The interface between the ACR101 (CCID) and the inserted smart card follows the specifications of ISO7816-3. 5.1. Smart Card Power Supply VCC (C1) The current consumption of the inserted card must not be higher than 50mA. 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 ACR101 (CCID) is connected to a computer through a USB following the USB standard. 6.1. Communication Parameters The ACR101 (CCID) is connected to a computer through USB as specified in the USB Specification. The ACR101 (CCID) is working in high speed mode, i.e. 480 Mbps, for the flash memory. Pin Signal Function 1 V BUS 2 D- Differential signal transmits data between ACR101 (CCID) and PC. 3 D+ Differential signal transmits data between ACR101 (CCID) and PC.
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. (The command for this will be discussed later on). CCID covers all the protocols required for operating smart cards and PIN.

FIRMWARE 10 bytes data for firmware version MAX_C The maximum number of command data bytes. MAX_R The maximum number of data bytes that can be requested to be transmitted in a response. C_TYPE The card types supported by the smart card reader. This data field is a bitmap with each bit representing a particular card type. A bit set to '1' means the corresponding card type is supported by the reader and can be selected with the SELECT_CARD_TYPE command.
