General Description

The NM95MS18 is an industry standard ISA Plug-n-Play controller that also supports Non-Plug-n-Play platforms like DOS, WIN3.1x, Windows-NT and Unix.

In additon to being completely compliant to ISA PnP Specification (Ver 1.0a), NM95MS18 integrates a total of 4Kbit of onchip EEPROM for both PnP Resource data as well as non-PnP configuration data to provide a true single chip solution.

NM95MS18 supports one logical device offering a flexible choice of DMA, Interrupt and I/O address decoding features within a single chip. NM95MS18 is implemented using Fairchild’s Advanced CMOS process and operates on a single power supply.
