Description

The NM95MS14 is the smaller of a family of devices designed 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 addition 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 onboard logic. This device provides a ``truly complete'' singlechip 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 Chipselect 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.
