Based on the VORAGO Technologies' VA108x0 family, this development board is based on a 32-bit ARM® Cortex®-M0 processor manufactured with HARDSIL® technology. The REB1 board is intended for room temperature operation only (0C to 70C) and is not intended to be used in an oven.

Key board features include:

  • PCB dimensions – 2.6” x 4.5”
  • 128KB boot SPI EEPROM
  • 3.3V and 1.5V regulators
  • On-board power distribution and monitoring
  • On-board clock generation (10MHz – 80MHz)
  • I2C-based temperature sensor
  • Power supplied through USB connector
  • Five LEDs : USB power, J-Link OB active, 3 for GPIO
  • Connectors with access to 39 GPIO
  • I2C and SPI PMOD compatible connectors
  • SPI-based 10-bit ADC
  • Segger J-Link OB

The microcontroller unit (MCU) employed within the product design, VA108X0 32-bit ARM® Cortex®-M0 MCU, is characterized by the following features:

  • Manufactured with HARDSIL® technology
  • Clock rate up to 50MHz
  • 32KB on-chip data SRAM
  • 128KB on-chip program memory SRAM
  • 24 general purpose counter/timers
  • 56 Dedicated general purpose I/O (GPIO) pins
  • 2 UARTs
  • 3 SPIs (two master/slave, one master only)
  • 2 x I2C
  • On-chip EDAC and Scrub Engine (VA10820 only)

Applications of this development board include:

  • Industrial
  • Oil & Gas
  • Aerospace
  • Automotive
  • Space
  • Medical
  • Military

Two options are available to customers:

  • REB1-VA10800 (to support VA10800 extreme temp. MCU)
  • REB1-VA10820 (to support VA10820 rad-hard MCU)

The software provided with this development board includes the following:

  • Board Support Package (BSP)
    • Example software to demonstrate all peripherals
    • CMSIS compliant
  • REB1 supported by KeilTM MDK-ARM microcontroller software kit, IAR Systems Embedded Workbench, iSYSTEM winIDEA, GCC compiler and FreeRTOS real-time operating system.
