Chip List

processor info

  • BGA package
  • 288 pins
  • .65mm pitch
  • 15x15mm
  • has onboard usb device
  • 12mhz xtal
  • 27mhz xtal (suspect it is for the audio interface)
  • unknown barrel xtal(suspect it is rtc)
  • ARM926EJ-S
  • possible JTAG on pads
* TP8 - Vcc
* TP9
* TP10
* TP11
* TP12
* TP13
* TP14 - Vss
  • marked with "LF-1000"
  • marked with "ARM"
  • marked with "N12N1D"
  • marked with "H0815"
  • onboard tft controller
  • onboard i2s or ac97 interface
  • 393MHz

after some careful research and elimination, it appears that the processor might be a variation of the STn8811 or STn8815 from ST which now is a part of NXP. the bga packaging and layout of the pins appear to be very very similiar. in addition, the STn8811 and STn8815 are the only commercially announced ARM926EJ-S that operates ate 393MHz.
