Detailed Features List of i.MX31ADS board

 

This is a development tool which is designed to run software applications designed for i.MX31 (MCIMX31) microprocessor unit (MPU).

The MCIMX31ADS includes a baseboard, a CPU board, a power management board, an LCD display panel, a keypad, a NAND Flash card, an image sensor, etc. It supports application software, target-board debugging, or optional extra memory.

 

Features
  • Three board system
    • Base board with display and interface connectors
    • CPU board with i.MX31 ARM-11 MCU
    • Power management board with MC13783 Atlas chip
  • +5.0 VDC, 2.4 A universal power supply
  • QVGA LCD display panel with touchscreen capability and LED backlight
  • Keypad with 64 push button keys
  • Image sensor camera
  • Configurable intelligent management of system power
  • Separate selectable voltage regulators for running the CPU board in stand-alone mode
  • Two selectable system clock sources, 32.768 kHz and 26 MHz
  • Onboard CPLD that manages memory-mapped expansion I/O, interrupts, and general-purpose I/O
  • Multi-ICE debug support
  • 32 MB of 16-bit NOR burst flash memory
  • 16 MB of 16-bit PSRAM
  • 128 MB of 32-bit DDR SDRAM memory
