Connects to ARM-20 JTAG interface. Note that the power to the personality chip connects to Vsupply and the feeds back into Vref. If Vsupply is unconnected, use the VCC pin on the PCB to provide 3.3V.

Connectors are S9205-ND and S9712-ND.

Original uses P25Q80H. W25Q80DV also works. Depending on flash chip, WP may need to be held high to program.

  • U1 - W25Q80DV (W25Q80DVSNIG-ND)
  • C1 - 0.1uF 0402
  • C2 - 330pF 0402
  • R1 - 10k 0402
