Info Box Applies to BORA Xpress

Contents

IntroductionEdit

BORA Xpress is the top-class Dual Cortex-A9 + FPGA CPU module by DAVE Embedded Systems, based on the recent Xilinx "Zynq" XC7Z015 / XC7Z030 application processor. BORA Xpress offers great computational power, thanks to the rich set of peripherals, the Dual Cortex-A9 and the Artix-7 FPGA inside. BORA Xpress is designed in order to keep full compatibility with the ULTRA Line CPU modules, to guarantee the premium quality and technical value of those customers that require top performances.

The Hardware section provides detailed information about hardware interfaces and characteristics. This document will provide a functional overview of the module and will focus on system-related issues.

Block diagramEdit

The following picture shows a simplified block diagram of BORA Xpress module.

Product HighlightsEdit

• Unmatched performance thanks to Dual ARM Cortex-A9 @ up to 1GHz
• SERDES: Xpress lanes up to 6.25 Gbps
• All memories you need: on-board NOR and NAND Flash
• Enabling smarter system thanks to Artix-7 or Kintex-7 FPGA integrated on-chip
• FPGA banks wide range PSU input from 1.2V to 3.3V
• Highest security and reliability: internal voltage monitoring and power good enable
• Reduced carrier complexity: dual CAN, USB, Ethernet GB and native 3.3 V I/O
• Easy to fit thanks to its small form factor
• Accurate timing application thanks to on-board 5ppm RTC
• Pin2Pin Compatibility with BORA SOM based on Zynq XC7Z010/XC7Z020
