is anyone selling any 43256-LP12 static rams or equivalents?

[777xxx]

i need 2 and i think they are overpriced on ebay. i dont mind paying a couple of quid for them. i think faster access chips will work too.

as long as they have the correct pins they should work.


any 32K-WORD BY 8-BIT or 256K-BIT should work too

im uk based btw

What price is "over priced"? How much?

£17 for 1 chip.

Farnells still stock them in DIL packages; eg.

If you are using stripboard or similar rather than it having to fit an existing PCB / socket, you can get a much larger RAM ICs from RS at around the same price:

AS6C4008-55PCN | Alliance Memory SRAM, AS6C4008-55PCN- 4Mbit | RS Components

My DRAMs are SMT not DIP variety, made by Winbond and AMD. No list with me when I posted this reply.

I agree with JRW RS do them for as little as 1.87 + vat..

I've managed to find plenty of LS00's, 21's and 153's, as well as a tube of SOP surface mount Hitachi HM62256ALFP-10T SRAM chips in my stock. The only ones I haven't managed to find yet are the LS08's, and I know I must have some around somewhere. You might be able to use the SRAM's with an adaptor board. Let me know if your interested in the parts, and I'll get some off to you if I can get your address, but it may be next week sometime.

Regards,

Sarah.

I also have 16 Samsung KM41256AP-12, 256K-by-1, DRAMS in 16-pin DIP package that may work in your application.
