B User Guide 6341A–ATARM–19-Oct-07 Section 1 Overview 1.1 Scope The AT91SAM9263-EK evaluation kit enables the evaluation of and code development for applications running on an AT91SAM9263. This guide focuses on the AT91SAM9263-EK board Rev. B as an evaluation platform. 1.2 How to Identify the PCB Revision The PCB revision can be clearly identified by looking at the board copper marking on the bottom layer. The last character of the series indicates the revision. Thus if the series of characters ends with the letter “B” (e.g. 63PC0608021B), your board is Rev. B. For Rev. A boards, refer to the corresponding , available on the Atmel web site. 1.3 Deliverables The AT91SAM9263-EK package contains the following items: ¡ an AT91SAM9263-EK board Rev. B ¡ one A/B-type USB cable ¡ one serial RS232 cable ¡ one RJ45 crossed Ethernet cable ¡ one CD-ROM that allows the user to begin evaluating the AT91 ARM ® Thumb ® 32-bit microcontroller quickly. 1.4 AT91SAM9263-EK Evaluation Board Rev. B The board is equipped with an AT91SAM9263 (324-ball LFBGA package) together with the following: ¡ 64 Mbytes of SDRAM memory ¡ 4 Mbytes of PSRAM memory on EBI1 ¡ 256 Mbytes of NANDFlash memory ¡ One NOR Flash memory (footprint only) ¡ One 1.8” Hard disk connectors ¡ One TWI serial memory ¡ One USB device port interface ¡ Two USB Host port interfaces AT91SAM9263-EK Evaluation Board Rev.
