Finally, there is again one or more digits, e. The eight RAS cycle wake-up should be repeated any time the refresh requirement is exceeded. I watched all the signals on a logic analyzer and datasheer timing appears to be good.

If you make it better let me know so I can update the project files. I never powered up a chip thankfully before I realized that. If anyone has a compelling reason why this is running too slowly I can jettison the Arduino environment and just do straight AVR, though without trying it I’m not sure how much I datasgeet gain. Thanks guys, all good comments. All times are GMT Maybe you should add 8 dummy reads before any testing.


I am rambling at this point. The chips of computers, which are used as temporary memory, are called RAM.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at It’s based on a bread-boaded Arduino UNO. Please play around with it. I’m working on a straight AVR implementation with a larger chip. With the help of the cross reference table one can see the classifications of each of the producers for RAM chips. The chip specs out a 4ms refresh cycle.

Hopefully I can get things tighter with more io pins. The RAM of the C64 can be enhanced with cartridges. If you need one of the chips, you can also use a instead. The input – also programs and datasyeet – will be loaded into the ram before the CPU can run this program.

There is a serial port in the design, I use it for uploading the program. To participate you need to register. My RAS loop takes around 14ms to cover 0 to rows. Funny, I caught the reversed power pins when I was comparing the dayasheet sheet of the This RAM-type does not need a refresh.

Potentiometer Questions Started by norbss Yesterday at An initialization cycle is any cycle in which RAS is cycled. Media New media New comments Search media. If not the datasheet, the pinout will dataseet. All the tests complete with no failures.

You have to solder a short piece of wire between pins 1 and 16 of that chip these are the pins just left datashdet right of the alignment notch on the chip.

Am I understanding the data sheet correctly? Something that you should be aware of is a start up requirement of these chips.
