Part number composition[edit | edit source]

BORA Xpress SOM module part number is identified by the following digit-code table:

Part number structure Options Description
Family DBX Family prefix code
SOC
  • A: XC7Z015 ARM Cortex-A9 866MHz - Speed grade -1
  • B: XC7Z015 ARM Cortex-A9 866MHz - Speed grade -2 without tranceivers
  • C: XC7Z015 ARM Cortex-A9 866MHz - Speed grade -3
  • D: XC7Z030 ARM Cortex-A9 866MHz - Speed grade -1
  • E: XC7Z030 ARM Cortex-A9 866MHz - Speed grade -2
  • F: XC7Z030 ARM Cortex-A9 866MHz - Speed grade -3
  • G: XC7Z015 ARM Cortex-A9 866MHz - Speed grade -2
System on chip definition (and FPGA speed grade)
NOR SPI
  • 0: 0MB
  • 4: 16MB
QUAD SPI NOR flash memory size - The limitation to max 16MB is due to this Errata from Xilinx. The proposed solution by Xilinx has not been approved by DAVE Embedded Systems
RAM
  • 1: 1GB
  • 9: 512MB
DDR3 Memory RAM size
NAND
  • 0: 0MB
  • 1: 1GB NAND SLC
  • 7: 128MB NAND SLC
  • 8: 256MB NAND SLC
  • 9: 512MB NAND SLC
Flash memory NAND size
Boot/Misc
  • 0: NOR boot, no Voltage Monitor
  • 1: NOR boot, voltage Monitor
Boot and Voltage Monitor options
Temperature range
  • C - Commercial grade: suitable for 0/70°C environment
  • I - Industrial grade: suitable for -40/85°C environment
  • S - Super Commercial grade: suitable for 0/85°C environment
PCB revision
  • 0: first version
  • 1: revision A
  • 2: revision B
PCB release may change for manufacturing purposes (i.e. text fixture adaptation)
Manufacturing option
  • R: RoHS compliant
  • D: No RoHS, conformal coating, sealing
  • S: Leaded SnPb process, no RoHS compliant, conformal coating, sealing
typically connected to production process and quality
Software Configuration -00: standard factory u-boot pre-programmed

-01: MAC address DAVE -XX: custom version

If customers require custom SW deployed this section should be defined and agreed. Please contact technical support
