Where can I get Dip Cmos SRAM 64kx8 bit format?
I have an old homebuilt home controller built around an 80c51FA microcontroller.
I'd like to get some new ram for it in a DIP format, probably a 64 or 128 kbit x 8 bit format. I can use 28 or 32 pin DIPs. It currently uses 32kx8 HM62256 DIPs. (5V operation) Where can I get such a thing these days in small quantities? A specific part # might also help in my search. |

I get such parts from old 386 and 486 motherboards (L2 cache) ; most often they are socketed and so have long leads. Michael |

If you are in the UK, you can buy one here. http://www.cricklewoodelectronics.co...=search&page=1 Gareth. |

Er, what continent? In the US, I'd try the web for Jameco, JDR Microdevices (if they still exist) and B&D Enterprises. Mark Zenier Googleproofaddress(account:mzenier provider:eskimo domain:com) |
