This RAM-type does not need a refresh. There is a serial port in the design, I use it for uploading the program. Next, there are often one or more letters, which most stand for the housing shape.
With the help of the cross reference table one can see the classifications of each of the producers for RAM chips. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

While the preceding letters often hint to the producer, the following series of digits indicates the size and organisation of the memory. If you need one of the chips, you can also use a instead. Thank you very much. Any 8 cycles which perform refresh are adequate for this purpose. Does anyone have the datasheet for sharp LH or sanyo LM dram ic or can point a web page with it? To participate you need to register. I am rambling at this point. As also today with the PCyou have to not only choose the appropriate memory size, but you also have to know where the limit for the access time is.
