Part number composition

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 666MHz - Speed grade -1 B: XC7Z015 ARM Cortex-A9 766MHz - Speed grade -2 without tranceivers C: XC7Z015 ARM Cortex-A9 866MHz - Speed grade -3 D: XC7Z030 ARM Cortex-A9 666MHz - Speed grade -1 E: XC7Z030 ARM Cortex-A9 766MHz - Speed grade -2 F: XC7Z030 ARM Cortex-A9 866MHz - Speed grade -3 G: XC7Z015 ARM Cortex-A9 766MHz - 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
