PCM16C02

Configurable Multiple Function PC Card Interface Chip

Note, PC Card refers to technology developed to the PC

General Description

National’s PCM16C02 acts as a standard interface between

Card Standards determined by the PCMCIA Standards

Committee.

the PC Card Host bus and local card busses found on I/O

and memory PC Cards. This device allows the card designer

to focus on the design of the I/O functions while providing a

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

interfacing, and power management. The PCM16C02 was

specifically designed to take advantage of those functions

that don’t require card-side bus arbitration, while not giving

up any of the non-arbitration related functionality. However,

if card-side bus arbitration is required refer to the

PCM16C00 datasheet.

Features

PC Card bus interface

PC Card Standard configuration registers

100 pin TQFP package

Function 0 configurable as NAND Flash (NM29N16) in-

terface

Serial EEPROM Interface compatible with

MICROWIRE^TMEEPROM protocol

1-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 two interrupt capable ISA like I/O

functions on a PC card

The PCM16C02 provides a PC Card interface for any two

ISA like functions as function 0 and function 1 which allows

two functions to be placed on a single PC Card.

In addition, the PCM16C02 provides the capability to config-

ure function 0 as a NAND Flash (NM29N16) interface; sup-

porting all of the necessary control signals required to hand-

shake with NAND Flash (NM29N16) memory devices.

Power management and clock control

Common memory logic for common memory devices in-

cluding NOR Flash devices

The PCM16C02 is fully compliant with the PC Card Stan-

dard. This multi-function IC allows the system software to

setup I/O decode windows and provides the Attribute mem-

ory decode control that allow attribute read and write data

transfers.
