NM95MS14
Plug ’n Play Front-End Devices for ISA-Bus Systems
General Description
The NM95MS14 is the smaller of a family of devices de-
signed to provide complete Plug ’n Play Capability for ISA
bus systems. The NM95MS14 includes the necessary state
machine logic to manage the Plug ’n Play protocol in addi-
tion to switches for steering Interrupt and DMA requests. It
also features a built-in 2k bits of serial EEPROM for storing
the resource data specified in the Plug ’n Play Standard. In
addition, 4k bits of EEPROM is available for use by other on-
board logic. This device provides a ‘‘truly complete’’ single-
chip solution for implementing Plug ’n Play on ISA-Bus
Adapter cards. The NM95MS14 supports one logical device
with a flexible choice of DMA/IRQ selection and I/O Chip-
select generation.
NM95MS14 is implemented using National’s Advanced
CMOS process and operates single power supply. The
NM95MS14 is available in a 48-pin TQFP package.
