does "Undiluted Platinum" support PSP new ver. hardware(TA-082) ?
i don't think so !

Undiluted Platinum

PSP new ver. hardware(TA-082)

K5E5658ACM-D060 1.8V/1.8V(Upper)
K5E5658HCM-D060 3.0V/2.5V(Lower)

Actel ProASIC Plus FPGA just support 3.3V/2.5V
PSP new ver. hardware(TA-082) use 1.8V !!

Does anyone can confirm it ?

A change in one of the power supply voltages is unlikely :). The CPU and the GPU are both 90 nm devices since the beginning. For the core they could use 1.8 V. For IO they use a higher voltage. Also the samsung multichip DDR/Flash is unchanged!
I think between TA-079, TA-081, TA-082 there are no die shrinks. If U.P. will work I don't know. Probably not yet..
Something different: With a FPGA setup one could use 1.50 program piggyback with 2.xx id storage area. You can mix the firmware program and firmware settings between the original flash chip and the piggyback flash! Would that work ???

did you have TA-082 PSP ?
did you check TA-082 PSP's I/O voltage ?

i have and i checked
so i say "Undiluted Platinum" NOT support TA-082 !!

if !(TA-082 have 3.3V ver.) && !(Undiluted Platinum support 1.8V)
Undiluted Platinum NOT support TA-082 :p

No I do not have TA-082. So
if you measured it, then you must be right! :)

from samsung you can download the official part number decoder.


I do not know the partnumber of the samsung memory on the TA-082, i cannot see it on your picture.

A picture of a TA-079 has a
k5e5658hcm-d060, which is 3.0/2.5 V part, because the 'H', position 8 in the string means 2.5/3.0 volt.

What is your TA-082 samsung memory part number ?? I would like to know :)

A = 1.8/1.8 V !!
You are right and U.P. has a problem there.

0okm, do you know the 3 digit week code number above the part number?
I'm just interested about when samsung produced the flash chip, and how many PSPs may have this hardware...

the U.P. press release photo can be enhanced, perspective can be removed.

week code : 543

That means the flash chips on this board were created in mid October 2005 right?

Props to Ookm for spotting this! I hope they are right about these PSPs not being widespread, but it sounds like they are just trying to play down a major problem atm!

Hi there... so the biggest problem of U.P. for the ta-082 is, that the psp's sytem (i/o) voltages are all on the 1.8v level, and U.P. works with higher voltages... if that is all, the problem doesn't have to be that big at all. But the item does have my interest. Can anyone give me the partnumber af that Actel-uC and the other IC thats on the U.P. board?
It may be an interesting thing to make a small interface-board between U.P. and the TA-082.
1.8v is the way to go anyways... longer playtimes on the same battery... technically speaking, very nice from sony... for us a temporarily problem that can be solved... at least, if they didn't change anything else.....

If anyone is willing to answer my two questions, I'm willing to at least try something for the scene.
