Every semiconductor component manufacturer publishes a “reliability report” associated with each component. There are several means of reporting and representing these reliability statistics within the industry standard formats. The two major formats of “product reliability” are the abbreviated terms of MTBF (Mean Time Between Failure, in hours) and the FIT Rate (Failures Per Billion hours). These two terms of reliability factors are the most commonly used within the Electronics Semiconductor Industry. Reliability Models are based upon internal components specific to each product and will vary widely based upon the internal components technology family, and internal operating conditions for a given application. Reliability Modeling will extrapolate approximate product life-span calculations by utilizing known reliability factors from each component manufacturer, over a given temperature range and operating parameters. There are several industry standard software packages available for product reliability modeling. Smart Modular utilizes Item Software’s reliability model, the RDF2000 UTE C 80-810 Telecom Standard. Smart Modular Technology has derived the following reliability statistics based upon numerous specifics related to and including; internal component packaging, pin configurations, component density, and internal component substrate architecture. Product reliability modeling for Smart Modular Technology is based upon continual usage of the product, within accepted normal operating parameters. Compromise of the published normal operating parameters will adversely effect the product life-span reliability model. For a more detailed breakdown analysis, contact Smart Modular Customer Support.

The 3.3V board will have position 1 blocked and the 5V board will have position 9 blocked. The connector on the host must be keyed correctly to avoid damage to the board. The header on the host may be any .1” pitch 2x5 header with .025sqin posts with the appropriate position removed for keying. For example a Samtec P/N TSW-105-23-F-D-009 is the appropriate part number to for the 5V board. P/N TSW-105-1-23-F-D-001 is the appropriate part number for the 3.3V board. For the Legacy Short Connector, the header on the host shoudl be TMM-105-S-D-009 Standoff The Legacy Connector Drive uses a standoff that can be screwed or locked onto the host board. The mounting hole on the host board should be 0.125 inches in diameter to accommodate a screw or locking pins and should be spaced as indicated on the diagram in section 2.2.1. The low profile versions do not come with a standoff. Corporate Headquarters: P. O.

The stacking drive comes in two configurations: Top or Bottom. If only a single drive will be used on a system, use the Top configuration. In this configuration, J1 is used to connect the power and USB signals between the host and the drive. J2 is used only for board support in this configuration and will not use any signals on this connector. If board stacking is to be used, a Bottom drive and a Top drive can be used together. Each will have its own independent USB bus and appear as a seperate drive. The Bottom drive is the same as the top drive, except that it has additional headers mounted on top of it to connect with a second drive. On the Bottom drive, J2 and J3 are used to pass the second USB bus up to the Top board. J4 is a dummy header used for supporting the Top board and does not contain any signals. The Stacking Connector drives contains two Hirose DF9, 9Pin, 1mm pitch, friction locking, SMT receptacles for connecting to the host. The part number for this part from Hirose is: DF9B-9S-1V The mating part for use on the host may be any of the following Hirose Part numbers: DF9-9P-1V (with metal fitting, with boss) DF9B-9P-1V (with metal fitting, without boss) DF9A-9P-1V (without metal fitting, with boss) DF9C-9P-1V (without metal fitting, without boss) Both 5V and 3.3V are shown on the connector but only one is necessary. If the 3.3V drive is being used only 3.3V needs to be connected on the host. If the 5V drive is being used only 5V needs to be connected on the host. To be able to use either drive connect both power lines on the host. Two optional signals are brought out to pins 1 and 2 of the connector. If these signals are not used by the host, these pins must be left unconnected. Pin 1, Reset#, may be used by the host to apply a hardware reset to the drive. This reset signal is a 3.3V active low signal. The host may pull this signal low to force a reset to the drive controller. At all other times (including during power up) the host must present a high impedance to this signal. Reset# is pulled up to 3.3V on the drive Pin 2, WP#, may be used by the host to write protect the drive. This signal is a 3.3V active low signal that is shared between the host and the switch (if present) on the USB drive. The host may pull this signal low to write protect the drive. At all other times the host must present a high impedance to this signal. WP# is pulled up to 3.3V on the drive. The switch and this pin are logicallay OR’d- if either are set, the drive will be write protected. Corporate Headquarters: P. O.

The address is encoded as follows. Bit Description 3..0 The endpoint number 6..4 Reversed. set to 0 7 1 = In 3 bAttributes Byte 02h This is a Bulk endpoints. 4 wMaxPacketSize Word 0200h 6 bInterval Byte FFh Maximum packet size. Does not apply to Bulk endpoints 6.4.2 Bulk-Out endpoint The Bulk-Out Endpoint is used to transfer command and data from host to device. Table 6.4.2 - Bulk-Out Endpoint Descriptor Offset Field Size Value Description 0 bLength Byte 07h Size of this descriptor in bytes. 1 bDescriptorType Byte 05h ENDPOINTS Descriptor type. 2 bEnpointAddress Byte 02h The address of this endpoint on the USb device. The address is encoded as follows. Bit Description 3..0 The endpoint number 6..4 Reversed. set to 0 7 0 = Out 3 bAttributes Byte 02h This is a Bulk endpoints. 4 wMaxPacketSize Word 0200h 6 bInterval Byte FFh Maximum packet size.
