==== Winbond 25X16AVSIG (SPI Flash 16Mbit) ====
The IC designation on the board of the cobra dongle is U1.
{{Template:Winbond 25X16AVSIG}}
On the Cobra Dongle, pin 3 of the EEPROM is tied to VCC. Lifting this Pin from the board and tieing it to ground '''should''' prevent the flash from being erased.
=====Roles=====
Drives data to and from the Winbond flash chip.
====Cobra Test Points====
<div style="float:right">[[File:Cobra-TESTPOINTS.jpg|200px|thumb|left|Cobra - Testpoints to Winbond SPI flash]]</div><BR/>
There are test points that map out the Winbond flash shown in the diagram to the right.
==== DG/PS3/PC Selection switch ====
There is a switch that switched between Downgrade, PC and PS3 modes of the dongle.
When facing the switch, with the USB Plug to the left the pins are labeled 1 to 4 in the table below:
{| border="1" cellspacing="0" cellpadding="5" border="#999" class="wikitable" style="border:1px solid #999; border-collapse: collapse;"

! Pin !! Usage !! Connects to !! Remarks
|-
| 1 || PC Position || GND || A resistor is placed, by hand, between this pin and GND after the board is manufactured.
|-
| 2 || PC/PS3 Position|| AVCC (atmega 27) + Winbond /WP (PIN 3) || Ties to Pin 27 of atmega16 (AVCC) and /WP of Winbond Flash
|-
| 3 || PS3/DG Position|| TOSC2 of the Atmega (Pin 26)|| ???
|-
| 4 || DG Position|| GND || A resistor is placed, by hand, between this pin and GND after the board is manufactured.
