That's why I wrote: --- Order 1 flash chip per REX. (so, 3 chips if you want to build 3 boards)
Pick any version of the chip which matches this pattern: AM29F800BB-##E* Where: ## = Speed: 90 or lower (90 or faster) E = Package: Only E, TSOP * = Temperature range: Any Example (what I got): AM29F800BB-70EK --- It's complicated because, well it's complicated. Any of the parts which match the filter pattern will work. These are all old, running-out-of-stock parts, so there was only like 4 of the exact chip I used available, so the simple directions which would point to exactly one part, would be simple, but wrong. Other parts are also usable, and that exact part will run out soon, or indeed is probably already gone. That is the way with electronic components. It's a forest of *properties*, and sometimes you must filter on the properties you need, not on exact part numbers. Especially complex chips that come in 25 slightly different versions. I gave the exact part number I used just to provide an example of a correct one that fits the pattern. You can't use just any of the parts that come up from that Verical link, only the ones that match this pattern. Where I have a 70 in my part number, you can use any that have a 90 or lower. (actually I wonder if that is even really a requirement, to go no higher(slower) than 90, but that comes from Steven's original specs so I'm not fit to contest it!) The E must be an E. The K can be anything. -- bkw On Apr 23, 2017 3:49 PM, "Michael Brant" <[email protected]> wrote: > Brian, I am looking at the links on the page for building a REX.
