NM95MS16
Plug and Play Front-End Devices for
ISA-BUS Systems
General Description
The NM95MS16 is the smaller of a family of devices designed to
provide complete Plug and Play Capability for ISA bus systems.
The NM95MS16 includes the necessary state machine logic to
manage the Plug and Play protocol in addition to switches for
steering Interrupt and DMA requests. It also features a built-in 2
kbits of serial EEPROM for storing the resource data specified in
the Plug and Play Standard. In addition, 4 kbits of 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 NM95MS16 supports one
logical device with a flexible choice of DMA/IRQ selection and I/O
Chipselect generation as well as offering 16-bit addressing in
Mode 1.
NM95MS16 is implemented using Fairchild’s Advanced CMOS
process and operates single power supply. The NM95MS16 is
available in a 48-pin TQFP package and 52-pin PLCC package.
