Here's the followup article I promised.
First I'd like to thank those again whom I've already replied to by mail
for their help. Although I was told that the chip was in the '85 Memory
components handbook, I couldn't find it in there. I did, however, find
it in the '88 version of that manual that showed up here at school a few
days ago. I'll just go through a few of the things that I was looking
for.
Since I'm building this EPROM burner as one of my senior projects, I
needed this info, and I know some of you other hardware hackers might
like a glance at it.
Intel Claims ....
180ns D2764A-1 (CerDip), 200ns P2764A-2 (plastic) are Intel Intelligent
Programming algorithm and Quick Pulse algorithm compatible. This Quick
pulse algorithm looks pretty useful... 1 second to program and verify
the chip (providing your programming equipment can move that fast). The
chip also has the Intelligent Identifier circuitry built in.
OKEY-DOKEY ... Here are the programming voltages (Vpp and Vcc are at
5.0v for normal use) --
Quick Pulse : Vpp -- 12.75v Vcc -- 6.25v
Intelligent : Vpp -- 12.5v Vcc -- 6.0v
Intelligent Identifier : Device 0x08 Manufacturer 0x88 (Plastic)
0x89 (CerDip)
Thanks Again for your help.
P.S. Anyone have a pinout for a NEC 43256 32k x 8 Static RAM???
Thanks in advance for any help.
