EDIT: This has been solved. The chip is an ARM 920T (Datasheet: http://pdf.dzsc.com/ARM/ARM920T.pdf)
Hey everyone, recently picked up a quite interesting device for cheap, because I thought it would be interesting to reverse engineer it and create something more useful out of it. I'm pretty sure the SoC/Processor in the device has been re-branded. I know the system is running Windows CE 6.0, but I'm currently trying to find a way to erase the software running within Windows CE in order to simply use Windows CE and add my own software, so I'm looking for any and all info I can get on it, including information on the processor which is apparently re-branded.
The device itself is a PayChex PX2500 Biometric Time Clock. Based on information I've gathered from tearing it down, PayChex also rebranded the entire unit. It's actually a ZKT ECO Biopad 100. ZKT ECO being a security based company, I'm not surprised it's rebranded... they want the device to be as secure as possible, but anyhow, I have attached pictures of the Biopad 100's embedded computer. The chip I am attempting to identify is labeled "Multi-Bio 600" with the "ZKTECO" brand stamped on it. 600 being the clock speed in MHz.
I'm thinking it might also be possible to identify the processor from within Windows CE, so my next step is going to be attempting to access the Windows CE desktop. ZKTECO also provides a "universal" SDK for this thing, not sure directly what that applies to.. yet, but I'll find out soon!
Any and all help is appreciated. Thanks in advance!
