Hi everyone,
I'm new to this forum and I don't have any electrical engineering course background but I've been working with circuit boards for a bit now.
Anyway, I have a question regarding a Freescale microprocessor: (MC68336 series. User's manual can be found here: http://cache.freescale.com/files/microcontrollers/doc/data_sheet/MC683336_376UM_ZIP.zip)
Apparently, this processor has an SRAM standby mode. On the specific board I'm working on the SRAM and the SRAM Standby pin on the CPU is powered by a battery which has gone dead. Since the battery has died obviously the SRAM contents have been removed I'm assuming.
My question is: How can I revive this board? It doesn't make sense to simply replace the SRAM with new ones because theoretically the new ones would be blank as well.
Would I need to utilize the RESET function on the processor? If so, how do I even go about doing that??
Sorry if this is an amateur questions but everyone has to start somewhere!
Thank you so much in advance. I'm hoping this community will be able to help me out!
