Looking for Correct Chip
I am looking to replace the SRAM chip in a GameBoy cartridge (Pokemon). I am looking at the FRAM and nvSRAM chips so there is no need for a battery (at least for the FRAM). It needs to be 256kbit, wide voltage and a 28-pin layout. Which chip should I be looking at? Currently, the main contender is: FM18W08-SG. What is the difference between SG and SGTR as suffixes? Also, which chips would have a real time clock built in for use in the later games which are designed to keep time?
Thank you very much!
