3. INSTALLATION 3.1 PROCEDURE 3.1.1 ESD PRECAUTIONS Static electricity kills... electronics! Before handling the AT3515, please observe the following precautions to avoid ESD damage to the unit: • • • Keep the drive in its shielded bag until ready to install. Ground yourself by touching a grounded chassis frame of the computer, or use a grounded wrist strap before and during the installation process. Do not touch the exposed drive electronics or connectors.
3.1.4 MOUNTING The AT3515 may be mounted in any orientation. A total of four bottom and six side mounting holes are available for installation. The mounting holes require 6-32 screws with a maximum depth of 0.25 inch. The diagram given below is valid for all capacities of the AT3515 drive. The overall outside dimensions are 4 inches (101.6 mm) wide, 5.56 inches (141.22mm) long, and 0.473 inches (12 mm) tall. Please refer to the following drawing for dimensions and mounting-hole locations.

3.2.1 MASTER The drive is configured as a master device if no jumper is installed or if the jumper is installed on the master jumper block. 3.2.2 SLAVE The slave jumper allows the drive to be configured as a slave. 3.2.3 CABLE SELECT The Cable Select jumper allows the drive to be configured as a master or slave as determined by the drive’s position on an IDE cable. A maximum of two drives may be connected to one standard IDE cable. 3.
3.2.4 WRITE PROTECT The Write Protect jumper prevents data from being written to the drive. 3.2.5 FACTORY DEFAULT The factory default configuration is master. No jumpers are installed. 3.
3.3 IDE INTERFACE The AT3515 uses a unitized signal and power connector. Maximum cable length is 18 inches. Recommended cable length is 12 inches or less, especially if advanced PIO or DMA transfer modes are used. 3.3.1 IDE CONNECTOR PINOUT The signal to pin assignment for the 40-pin IDE interface connector is listed in the following table.
4.2 MTBF The MTBF can be logically calculated in hours using the following formula. # Flash Chips * # Blocks *Re-programming Cycles * Area Rate MTBF = -----------------------------------------------------------------------------------Average Programming Sectors per hour (1 sector = 512 bytes) Note: The program area is the area that is not changed once it has been programmed. The remainder of the drive is thus considered “Reprogrammable”.
4.3.3 POWER ROUTING Bad power can lead to bad data. To avoid “glitches” or noise on the Vcc and ground lines, power in the system should be routed so that all peripherals are sourced from the power supply in a star configuration, as opposed to routing a single continuous supply line to each device in the system. Routing power in the star configuration, as is done on most desktop PCs, will minimize the effect on one device’s current draw on another device.
