DIP-28, or PLCC32, packaged 27C256 32K x8 CMOS EPROM IC with 70nS, or 250nS, access time, manufactured by National Semiconductor or Atmel (Microchip). The EPROM is a non-erasable, or One Time Programmable, type without a window to allow UV erasure. EPROMs are programmed with the file you upload on the next page, maximum size is 32Kbytes (256Kbits). The file must be supplied in raw binary format, data in Intel Hex or similar formats should be converted before submission to ensure that the correct data is written to the IC. For large quantities, bulk pricing may be available. Feel free to enquire at: sales@ombertech.com |
