PREFACE Thank you for purchasing the SHARC® USB EZ-Extender®, Analog Devices, Inc. extension board to the EZ-KIT Lite® evaluation systems for ADSP-21262, ADSP-21364, and ADSP-21369 processors. The SHARC processors are based on a 32-bit super Harvard architecture that includes a unique memory architecture comprised of two large on-chip, dual-ported SRAM blocks coupled with a sophisticated IO processor, which gives a SHARC processor the bandwidth for sustained high-speed computations.
Product Overview Product Overview The SHARC USB EZ-Extender is a separately sold extension board that plugs onto the expansion interface of the ADSP-21262, ADSP-21364, or ADSP-21369 EZ-KIT Lite evaluation system. The extension board aids the design and prototyping phases of ADSP-21262, ADSP-21364, or ADSP-21369 processor targeted applications.
Preface Purpose of This Manual The SHARC USB EZ-Extender Manual describes the operation and configuration of the components on the extension board. A schematic and a bill of materials are provided as a reference for future SHARC processor board designs. Intended Audience This manual is a user’s guide and reference to the SHARC USB EZ-Extender. Programmers who are familiar with the Analog Devices SHARC processor architecture, operation, and development tools are the primary audience for this manual.
What’s New in This Manual • Appendix B, “USB EZ-Extender Schematic” on page B-1 Provides the resources to allow EZ-KIT Lite board-level debugging or to use as a reference design. B now is part of the online Help. The PDF version of L Appendix the SHARC USB EZ-Extender Manual is located in the folder on the installation CD. Alternatively, the book can be found on the Analog Devices Web site: www.analog.com/processors.

1 USB EZ-EXTENDER INTERFACE This chapter provides the setup procedures for both the SHARC USB EZ-Extender and EZ-KIT Lite (ADSP-21262, ADSP-21364, or ADSP-21369) and describes the USB interface the extender supports. USB EZ-Extender Setup It is very important to set up all of the components of the system containing the USB EZ-Extender before applying power to that system. The following procedure is recommended for the correct setup. Power your system when these steps are completed: 1.
USB 2.0 Interface 4. Set the jumper on the USB EZ-Extender board. Use the block diagram in Figure 2-1 on page 2-1 in conjunction with “Processor Select Jumper (JP1)” on page 2-2. 5. Set the switches on the EZ-KIT Lite board. If not already, familiarize yourself with the documentation and schematics of the EZ-KIT Lite (see “Related Documents”). Compare the expansion interface signals of the USB EZ-Extender board with the signals of the EZ-KIT Lite board to ensure there is no contention.
USB EZ-Extender Interface You can reset the NetChip 2272 device by asserting LOW these flag pins: • FLAG2 on the ADSP-21262 and ADSP-21364 processors • FLAG0 on the ADSP-21369 processor The USB interrupt request pin (IRQ) line of the extender connects to FLAG1 on the ADSP-21262, ADSP-21364, and ADSP-21369 processors. This flag pin may be used for push buttons or LEDs on the respective EZ-KIT Lites; consequently, the user must make the proper changes to that EZ-KIT Lite.

2 USB EZ-EXTENDER HARDWARE REFERENCE This chapter describes the hardware design of the USB EZ-Extender. The following topics are covered. • “System Architecture” on page 2-1 Describes the extension board’s configuration. • “Processor Select Jumper (JP1)” on page 2-2 Describes the configuration jumper’s functionality. System Architecture A block diagram of the SHARC USB EZ-Extender is shown in Figure 2-1. Figure 2-1.
Processor Select Jumper (JP1) Processor Select Jumper (JP1) Before using the SHARC USB EZ-Extender, follow the steps in “USB EZ-Extender Setup” on page 1-1. Figure 2-2 shows the location of the processor select jumper JP1. A two-pin jumper can be placed on the respective jumper header for different functionality. Figure 2-2.
USB EZ-Extender Hardware Reference Table 2-1 describes the jumper settings and functionality. The jumper, by default, must have no jumpers on any of its pins. Table 2-1. JP1 Settings EZ-KIT Lite JP1 Setting ADSP-21262/ADSP-21364 No jumpers (default) ADSP-21369 Installed using the extender with an ADSP-21262 or ADSP-21364 L When EZ-KIT Lite, you must not place any jumpers on . Placing a JP1 jumper on JP1 can damage the extender card and/or the EZ-KIT Lite.
