With the help of the cross reference table one can see daasheet classifications of each of the producers for RAM chips. Hopefully I can get things tighter with more io pins.

If you need one of the chips, you can also use a instead. Thread Tools Show Printable Version. Or am I covering the refresh ok? 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. I’m going to find some ‘s to test as well. To participate you need to register.

The time datassheet is For a better experience, please enable JavaScript in your browser before proceeding. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Three LED’s will indicate the status, and then it will continue to loop. If not the datasheet, the pinout will do. Next, there are often one or more letters, which most stand for the housing shape. While the preceding letters often hint to the producer, the following series of digits indicates the size and organisation of the memory.

Three of these chips expandable by another 8 make up the main memory in the VIC The information of a DRAM must be refreshed after a few milliseconds. You must log in or register to reply here.

The chip-synonym is The eight RAS cycle wake-up should be repeated any time the refresh requirement is exceeded. An initialization cycle is any cycle in which RAS is cycled. Maybe you should add 8 dummy reads before any testing.

The RAM of the C64 can be enhanced with cartridges. All times are GMT If anyone has a compelling reason why this is running too slowly I datasheet jettison the Arduino environment and just do straight AVR, though without trying it I’m not sure how much I will gain.
