NM95MS15
Plug and Play Front-End Device for ISA-Bus Systems
General Description
The NM95MS15 is one of the family of single chip solutions
designed to provide complete Plug and Play capability for
ISA bus systems. The NM95MS15 includes the necessary
state machine logic to manage the Plug and Play protocol in
addition to switches for steering Interrupt and DMA re-
quests. It also features a built-in 4k bits of serial EEPROM
for storing the resource data specified in the Plug and Play
Standard. In addition, 4k bits of the EEPROM is available for
use by other on-board logic. This device provides a truly
complete single-chip solution for implementing Plug and
Play on ISA-Bus adapter cards. The NM95MS15 supports
two logical devices with a flexible choice of DMA/IRQ selec-
tion, I/O, and MEMORY Chip Select generation.
NM95MS15 is implemented using National’s advanced
CMOS process and operates from a single power supply.
The NM95MS15 is available in a 64-pin TQFP package.
