Configurable Multiple Function PCMCIA Interface Chip

General Description

Features

PCMCIA Bus Interface

National’s PCM16C00 acts as a standard interface between

the PCMCIA bus and card-side local bus for I/O and memo-

ry PCMCIA cards. This device allows the card designer to

focus on the design of the dual I/O functions while providing

a one-chip solution for I/O memory window control, concur-

rent interrupt control, EEPROM interfacing, and power man-

agement. In addition to being configurable to interface to

any two ISA compatible I/O functions, the PCM16C00 sup-

ports logic necessary to simplify a design that uses the Na-

tional DP83902A ST-NIC Ethernet Controller as one of the

functions.

Compliant with multi-function extension to PCMCIA

Standards 3.X

PCMCIA version 2.1 configuration registers

Serial EEPROM interface compatible with MICROWIRE

EEPROM protocol

2-kbyte on chip RAM for attribute memory which shad-

ows the CIS and is used for loading static registers

Address decoding and control for 2 I/O functions

Logic to support any two interrupt capable I/O func-

tions on a PCMCIA card

The PCM16C00 is fully compliant with PCMCIA version 2.1

and is compatible with serial 4-kbit and 16-kbit EEPROMs

with 8-bit and 16-bit organizations that use the MICROW-

IRE^TMprotocol. This multi-function interface IC allows the

system software to setup I/O decode windows and provides

the Attribute memory decode control that allow attribute

read and write data transfers.

Power management and clock control

Programmable arbitration unit for PCMCIA host and two

functions

Common memory logic

National DP83902A Ethernet LAN support logic

4 Bit, direction programmable, generic digital port

ISA-like interface to card function
