Circuit use SST29EE010 Memory

Hi, Is there anything special needed to do from a hardware angle to use SST29EE010 Memory chips on a small 68000 system that I am building. In the past I have been using 27C512 ROMs for my program and I have had to reprogram the ROMs every time a found a bug or add a new hardware module. I have now got a comms port up and running and I would like to change the ROMs so the the system can reprogram is self on the fly. This will reduce the development time and increase the protental of my project. Is it a case of hooking up the address, data chip selects, read and write lines to the processor and then it is ready to use. Am I correct in that all I then need to do is write three bytes of data to the correct address followed by the data that I wish to program. Thanks for any details that can be given. Kenneth Keeley

You are writing a boot loader. Don't forget that the program for the boot loader mustn't get erased when you erase the flash, so either keep that bit of the program in a separate EPROM, or don't do 'erase all'. Other than that, if the timings are right (and they probably are if it worked with EPROM), there's only the slightly different pinout to remember- it looks more like RAM than EPROM IIRC.
