Posted - 01/29/2011 : 16:11:09 Hi,
I have spend days searching for a DIP32 E/EPROM or FLASH that meets the following specs: 3.3V, DIP32 / DIL32
Can you point me to one that actually can be purchased?
There is nothing in production that I can see. Almost all is 5V or PLCC32 for 3.3V.
I have some NICs that use DIP32 for boot prom but are 3.3V - I have no idea why they would design it that way, but hey - what can you do.
Any recommendations welcome.

150ns AT49BV512-15PC AT49BV512-15PI
32 pin dip, 3v 512kb
Found on a NIC I was just replacing and thought of this post. |

Something like: hxxp://cgi.ebay.co.uk/PLCC32-PLCC-32-DIP32-Adapter-Universal-Xeltek-UP48-/360342965579?pt=LH_DefaultDomain_0&hash=item53e61d4d4b#ht_2688wt_1026 |

Posted - 02/15/2011 : 20:19:04 Sure for programming it is the programmer. But for normal operation it is for example the NIC controller (e.g. Realtec RTL8139C) which uses a 3.3V boot PROM/FLASH/EEPROM.
In cases like that the VCC is actually 3.3V not 5V. This becomes more and more common. And in one NIC I actually have a DIP EPROM socket that is 3.3V powered - escapes me why anyone would design it that way in the first place - maybe because the DIP sockets are cheaper than the PLCC.
The real problem here is that there are no DIP FLASH/PROM/EPROM/EEPROMs I could find.

Posted - 02/01/2011 : 11:41:52 the voltage should be controlled by programmer, not the adapter. If your chip is DIP chip, then you do not need the adapter. |
