You won't be storing videos or doing photo editing and probably won't even be listening to music on it.

Here although it does not have code specific to operating the flash ICs. (The 32's are four megabytes, and the 64's are eight.) There's a one-page. The board is made for W25X40CL, 25VF016, 25VF032,Ģ6VF032, 25VF064, 26VF064, CY15B104Q or any other SPI flash or FRAM ICs in a normal or wide SO-8 package with the same pinout. suppliers.įlash or FRAM memory module, again very hobbyist-friendly.

Easiest payment method is usually Paypal, to my email address, 300" row spacing, because of the extra labor involved in improvising the connector.) Partially loaded modules are availableįor less. Add postage of course, and sales tax if going to a California address. More per piece that I had been paying for the Cypress one though, so I'm raising the price for a fully loaded module (ie, with 8 The module data sheet linked above reflects this. Would cost me now, so I've gone to the ISSI part. Further, the ISSI part is much cheaper than the Cypress part Minor to affect the hobbyists who would be buying the module. AfterĬomparing the data sheets in detail, I concluded that the several differences (mostly improvements over the Cypress part) were too The ISSI IS61C5128AL-10KLI was recommended as a substitute. Probably buying them up faster than they can be made. More than doubled, and although it was still in production, there was no stock anywhere which makes me think some contractor is (I won't use Chinese or eBayĭistributors, as I've been burned before.) In the first week of April of 2020 however, I went to buy more, and the price had for less than half of what you would probably have to pay for just a few. I've been getting the ICs in quantity from a legitimate Cypressĭistributor in the U.S. The price has gone up and down with the price of the ICs. IĬan provide the sockets too, both in soldertail (for $2.89 each) and in wire-wrap (for $5.50 each). SBC-4 computer which he sells (pictured above) uses it. There's more discussion of it on the forum

It is free of the complications of DRAM management requirements.

Populated, it has 64 times as much RAM as the Commodore 64 did, and 32 times as much as the original Mac did. This is the densest, fastest 5V SRAM module that I know of, and its pin header makes it hobbyist-friendly. Parallel to the mother board), or now also with rows at.
