White Electronic Designs DimmDrive Solid State ATA Flash Module WED7GxxxATA33 *PRELIMINARY FEATURES DESCRIPTION n 144 Pin SO-DIMM, JEDEC package The DimmDrive WED7GxxxATA33 is a high performance single chip flash disk module available in 144 Pin SO-DIMM package. The module is based on SanDisk NAND Flash technology and utilizes the 128Mb, 256Mb, 512Mb or 1Gb memory components to provide the maximum in module density. n Plug-and-play solid state disk n NAND Flash memory technology by SanDisk n PC CARD ATA compatible - memory mapped or I/O operation n 3.3 volt & 5.0 volt power supply operation The DimmDrive WED7GxxxATA33 utilizes a SanDisk Flash ChipSet controller which is designed specifically for use as a Flash mass storage controller for the SanDisk memory devices. This interface allows a host computer to issue commands to read or write blocks of memory in the Flash memory array. The intelligence to manage the interface protocols, data storage and retrieval as well as ECC, defect handling and diagnostics are controlled by this device. Automatic power management and clock control is handled by the controller as well. n 16MB - 768MB memory density - (1GB - Q3/02) n Low Power Consumption n ECC error correction n Supports true IDE mode n 8Kbyte data buffers n Broad O/S support: DOS, Linux, Windows 3.X, Windows 95, Windows NT4.0/5.0, Windows CE, others The DimmDrive WED7GxxxATA33 module will have the same functionality and capabilities of an intelligent ATA (IDE) disk drive. An advantage of the on board Flash controller and it's ATA command set, is the ease of software development by the user. Once the device has been configured by the user, it appears to the host as a standard ATA disk drive. Additional ATA commands have been provided to enhance the system performance. n Compatible with major processors: x86, Media GX, PowerPC, 68K, MIPS, SHx, StrongArm, others n Full Hard Disk emulation and Boot capability n Easy to use interface, JEDEC standard n Supports power down commands and sleep modes n Commercial temperature range 0C + 70C n Industrial temperature range -40C +85C The on-board controller is a highly integrated solution and the controller is designed to handle all intelligent operations, even the rare cases when new defects arise and need to be mapped out or replaced by a spare. The hardware performs the complicated task of ECC detection and correction and will return good data to the host. The controller manages all defects and errors and makes the Flash memory appear as perfect memory to the host. MODULE APPLICATIONS Embedded systems Internet Access Devices Set Top Boxes The DimmDrive WED7GxxxATA33 module also provides a more cost effective solution to the traditional hard disk media. The module is perfect for applications requiring upgradeability to higher densities and for those applications with limited space availability and power consumption requirements. WEB Browser Routers, Networking WEB phones, car PC, DVD, HPC Point-of-sale Medical and Telecom Unlike standard IDE drives, no cables or extra space is required. The module has no moving parts providing significant reduction in power consumption and increasing reliability. Simply insert the module into a standard 144 Pin SO-DIMM socket and you then have a bootable flash disk. Other applications requiring embedded or solid state storage * This datasheet is preliminary, therefore all specifications are subject to change without notice. July 2002 Rev. 0 ECO #15433 The DimmDrive WED7GxxxATA33 is available with memory densities of 16MB to 768MB today with 1GB density available in Q3/02. 1 White Electronic Designs Corporation • (508) 366-5151 • www.whiteedc.com White Electronic Designs WED7GxxxATA33 MODULE PINOUT PIN 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 SIGNAL NOTE VSS VSS DQ0 Reserved DQ1 Reserved DQ2 Reserved DQ3 Reserved VCC VCC DQ4 Reserved DQ5 Reserved DQ6 Reserved DQ7 Reserved VSS VSS CE0\ Reserved CE1\ 1 Reserved VCC VCC A0 A3 A1 A4 2 A2 A5 2 VSS VSS PIN 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 SIGNAL NOTE DQ8 1 Reserved DQ9 1 Reserved DQ10 1 Reserved DQ11 1 Reserved VCC VCC DQ12 1 Reserved DQ13 1 Reserved DQ14 1 Reserved DQ15 1 Reserved VSS VSS Reserved Reserved Busy 4 NC BVD1 3 BVD2 3 VCC VCC RST 4 IOWR 3 WE\ IORD 3 Reserved REG 3 Reserved INPACK 3 PIN 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 SIGNAL NOTE OE\ IO16 3 VSS VSS Reserved Reserved Reserved Reserved VCC VCC Reserved Reserved Reserved Reserved Reserved Reserved Reserved Reserved VSS VSS Reserved Reserved Reserved Reserved Reserved Reserved Reserved Reserved VCC VCC A6 2 A7 2 A8 2 NC VSS VSS Note: 1.) 16-Bit bus mode signals not used (floating) in 9-bit mode CE1\ signal in 16-bit only mode should be tied to CE0\ 2.)

CE0\ accesses the even or odd byte depending on A0 and CE1\. For 8-bit systems, CE0 is used and for 16-bit systems, both CE0\ and CE1\ are used. Both CE0\ and CE1\ should be decoded by the logic to determine the memory window. This is an output enable strobe generated by the host interface. It is used to read data from the Flash ChipSet in Memory Mode and to read the CIS and configuration registers The write enable pin is driven by the host and used for strobing data to the registers of the Flash ChipSet when the Flash ChipSet is configured in the memory interface mode. It is also used for writing the configuration registers. A0-A3 selects the basic registers of the controller to communicate to the module. This requires 16 bytes of host address space. A0 is optional if CE0\ and CE1\ are combined to enable 16-bit wide register access. The Busy signal is driven low when the product is accessing memory. When Busy is high, register access is allowed. After a data transfer command is issued, this signal is used to signify that the host can transfer data. When RST is high, the product is placed in a reset mode. This signal is only valid at power on. This signal is driven high since a battery is not used with this product This output line is always driven to a high state in Memory Mode since a batery is not required for this product This signal is not used in the memory mode. This signal is not used in the memory mode. This signal is used during Memory Cycles to distinguish between common memory and register memory accesses. High for common memory, low for attribute memory. This signal is not used in the memory mode. Optional test signals not used in the Memory Mapped Mode. Pins are reserved for future expansion and must be left floating. Power pins. All VCC pins must be connected. Ground pins. All VSS pins must be connected. No connect. Pin internally not connected.
