It is also a intelligent adapters that comply with USB specification and generate signal of accessing Memory Card .It uses bus power via USB cable ,so not need external power supply. USB Device Driver running on host PC make a control of Memory Cards that store the image for camera and the music for MP3 player. It is just data converter from USB to MMC or SSFDC Signals or from memory cards to USB PC.

It contains MMC Interface that is supports bidirectionalCMD,DAT pin, so it dose not need external PLD for MMCmode Access.

It support above 32M bytes SSFDC ,that is, generates4 cycle address to SSFDC.

It’s MCU interface serial channel,GIPO pin work wellto interface the System MCU that is integrated to MP3,portable system.

1.0 Device Overview

The GDS30C6001 is an Complete USB Device Controller for interfacing of Flash Memory,MMC and SSFDC.The block diagram on page 2 of the data sheet show the major on-chip components of the device.

1.1 Transceiver

The GDS30C6001 contains a high-speed transceiver, which consists of three main functional blocks: - differential receiver - single-ended receiver with on-chip voltage reference - transmitter with on-chip current source The performance requirements met by this transceiver are described in Chapter 7 of the Universal Serial BusSpecification Version1.1.The differential receiver operates over the complete common mode range , that is guaranteed to be larger than that of the single-ended receivers,to avoid poten-tial glitche in the Serial Interface Engine (SIE) after S-ingle-Ended Zeros.Single-ended receivers are present on each of the twodata lines. These are required, in addition to the differ-ential receiver, to detect an absolute voltage with a s-witching threshold between 0.8V and 2.0 V(TTL inputs) An external 1.5 K Ohm resistor ,tied to a voltage sou-rce between 3.0V and 3.6V referenced to the local gr-ound,is required on D+ to indicate that this is a high-speed mode.

1.2 Serial Interface Engine(SIE)

The USB Serial Interface Engine (SIE) is Phyical Lay-er interface . The SIE includes the digital clock recove-ry circuit, a digital glitch filter, END_OF_PACKET dete-ction circuitry, and bit stuffing and unstuffing logic. Als-o it does packet formatting,CRC generation and chec-king, generation of the NAK,ACK,and STALL respons-es as determined by Device Control for the specified endpoint pipe. The SIE is also responsible for detect-ing and reporting events on detection of USB-specific events such as Reset,Suspend,and Resume.

The USB standard specific bit stuffing and unstuffingas a method to ensure adequate transitions on the l-ine to enable clock recovery at the receiving end. W-henever a string of consecutive 1s is encountered, the bit-stuffing logic inserts a 0 after every sixth 1in the data stream. The bit-unstuffing logic reverses t-his process.The clock recovery block uses the incoming NRZI d-ata to extract a data clock(12MHz) from an input clo-ck derived from a crystal(48MHz). This clock is usedin the data recovery circuit. The output of this block is binary data (decoded from the NRZI stream) thatcan be appropriately sampled using the extracted 12 MHz clock. The jitter performance and timing chara-cteristics meet the requirements set forth in Chapter 7 of the USB Specification

1.3 USB Device Control/Vendor Command Decoder

The Device Control contains a state machine that un-derstands the USB protocol. The SIE provides the D-evice Controller with the type of packet,address value,endpoint value,and data stream for each incoming pa-cket. The Device Control then checks to see if the pac-ket is targeted to the device by comparing the address/endpoint values with internal registers that were load-ed with address and endpoint value during the USB enumeration process. Assuming the address and end-point is a match, the Device Control then interprets thepacket. Data is passed on to the endpoint for all packetsexcept SETUP packets, which are handled specially.Data toggle bits (DATA0 and DATA1 as defined by theUSB Specification)are maintained by the Device Contr-oller. For IN data packets(device to host)the Device C-ontroller sends either the maximum number of bytes ina packet or the number of bytes available from the end-point. All packets are acknowledged as the spec.For SETUP packets, the incoming data is extracted intothe relevant internal field,and then the appropriate action is carried out.

�




The Control/Status Register is a register bank for sto-ring Specific Card commands and Status values. It istransmitted to GDC30C6001 via the vendor specific commands that is made for Flash module. USB HostPC gets/sets these value using default endpoint.TX FIFO is the Endpoint1 FIFO which depth is 32 by-tes and the target for bulk out transfer.RX FIFO is the Endpoint2 FIFO (32 bytes) that receiv-e data from Flash module and then buffers for IN token.

1.5 MCU I/F SSFDC Control/MMC Control

GDS30C6001 provides serial interface for the MCU of the target system (MP3, Digital still camera). MCUI/F generates serial clock , serial data out to MCU and receive the serial data in from MCU according to serial clock as mentioned above. That is, MCU I/F isthe master of Serial communication to MCU. The Spe-ed of Serial Clock is controlled by the specific vendorcommand.It send specific control of the system and get the ven-dor ID/Product I/D before USB access the device de-scriptor.SSFDC Control generate control signals,data path si-gnal for accessing SSFDC. It’s state machine operates properly for SSFDC.MMC Control supports /MMC Mode. It contains DAT,CMD bidirectional Port.

2. MCU I/F for the System(MP3)

Note*

1. Using 6001, You want to transfer data from PC to Flash or from Flash to PC, PC S/W turn on one pin of GPIO5,GPIO6,GPIO7 to ‘1’ that is the interrupt sourcefor MCU.After that, the MCU change its pins( RD1,RD0,RF0 for MMC, SM signal) for Flash access to Tri-state.After finishing data Transfer of 6001, it is turned off ‘0’ by PC S/W.When the MCU has to access flash,You have to change the 6001’ pins(MMC signal,SM signal) connected to flash module to tri-state using SET_MODE Command that makes these tri-state automatically. (SET_MODE = ‘h00)

2. When the USB cable is disconnected , 6001 has no power state ,if you use bus power for 6001. But 6001 is not completely power off, You have to use Register or something to discharge 6001.

3. For SM, CE signal is connected to GPIO3 or GPIO4 that is tri-state pads.

NOTE : * You does’nt use EERPOM and MCU I/F for Access Vendor ID, You may Connect DATA_IN to GND or VCC. But You can be have a problem that Windows is confused by several Device with 6001 operating in the Same PC at the same time if there is no Specific ID. In case ,You have to solve this problem with your S/W.

If You have no Vendor ID, You can use Hyundai ID and Special Product ID that must be unique in the system using 6001. For example, 05B4, 1234.. Also, Hyundai have a management to Special Product ID for Customers having no ID
