BORA Xpress XILINX Zynq CPU module[edit | edit source]

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.

Main Features[edit | edit source]

• 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

BORA Xpress Evaluation Kit[edit | edit source]

BORA Evaluation Kit BELK is a development/test board designed to start working with the BORA Xpress platform and experimenting with the implemented features. The carrier board hosts an BORA Xpress CPU module and offers the following features:

• 10/100/1000 Ethernet #0 (PS)
• 10/100/1000 Ethernet #1 (Routed through EMIO)
• 1x USB 2.0 OTG (MicroAB connector)
• 1x Serial port (RS232 DB9)
• 1x MicroSD
• External DDR3 SDRAM bank
  • This memory bank is connected to bank 35 - powered @ 1.5V - that is optimized at PCB level to interface such devices.
  • This bank is expressly available for peripherals and/or IPs implemented in FPGA fabric. This solution permits these blocks to work without impacting on Bora's DDR3 memory bandwidth. To access this bank, MIG (Memory Interface Generator) controller has to be implemented on PL.
    • MIG controller requires an external 200 MHz clock source.
• State-of-the-art programmable MEMS clock generator (Silicon Labs Si504): this is an alternative clock source to allow the user to easily experiment his/her own peripherals and IPs on FPGA
• XADC
  • Some signals of Bank 35 can be configured as XADC signals. For this reason they can be routed alternatively to 2.54mm-pitch connectors, instead of DDR3 memory.
• JTAG port
• Trace port
• Socket for DWM Wireless Module
• Digilent Pmod™ Compatible expansion connectors
• Headers for external for NAND flash and SPI NOR flash
• 2.54mm-pitch pin-strip connectors for Bora PS and PL configurable peripherals (MIO and EMIO interfaces, GPIOs, custom IPs, ..)
• Jumpers for voltage selection of the PL banks
• +12V power connector
