CPU characteristic

  •      454MHz ARM926EJ-S kernel with 16KB/32KB cache
  •      PMU carry highly effective on-chip DC/DC, support li-ion battery
  •      dual 10/100 l IEEE? 1588 ethernet,provide support for RMII and L2 exchange function
  •      dual CAN interface
  •      LCD controller with touch screen
  •      NAND support – SLC/MLC and eMMC 4.4 manageable
  •      hardware BCH (up to 20 bit correction )
  •      200 MHz 16 位 DDR2, LV-DDR2, mDDR supported by external storage
  •      carry embed PHY dual high speed USB
  •      8 universal 12 bit ADC channel and one 2 Msps ADC channel
  •       with temperature sensor, to provide thermal protection
  •        a few kinds of connection interface
  •        3V I/O,10 years of service life (industrial control)
  •       package and temperature
  •       289 BGA 14x14mm .8mm
  •      -40C to +85C (industrial control)
  •      these items are included in long term supply by Freescale,who guarantee at least 15 years' supply from the day one of marketing.
  •      core board adopt stamp hole to guarantee stability and credibility of high speed signal and ensure a nice connectivity,which can withstand violent shock and can completely meet the test of violent shock in harsh environment for industry and automobile.
