Revision Info:
2
Changes for x06:
X06: changed 1k pull-down on R32 and R34 to 0603 from 0806
Changed from x05 (swapped xtdi and XTDO)
Swizeled LCD connector signals:Need to swizel these pins - P12 to P1 and
P1 to P12 and everything inbetween
Changed R10 (FRU pull down) from 470 to 330 to reduce r count
Replaced Power LED with a single color GRN. Saves 15 cents :)
3
Added several cap sizes to CP near 5V_FP and DS2 to resolve
ESD issue which cuases reset with -15Kv
x06: Moved 3.3vAux_PWRGOOD from pin 14 to p16
+ Changed LED resistance to 150 ohms. to get 20 mA thru the part.
3
Changes for x07 / A00
+ PWR LED AVL / DPN - still in process This is a BOM only change
Changes for A02
4
+ PWR LED AVL / DPN - Actually changed part on schematic to match BOM change made in A01
+ Changed U3, LM-75 from 0C085 to 5Y977. Parts 0C068 can cause a permanent I²C Bus lock-up
that can be cleared ONLY by removing power to the LM-75. This can be caused by the
interruption of communications with the LM-75, such as when the bus master is reset.
The parts under 5Y977 have passed a lockup qualification test to help insure that they
are not prone to this failure mechanism.
