PCM16C00 Datasheet | National Semiconductor

Description National’s PCM16C00 acts as a standard interface between the PCMCIA bus and card-side local bus for I O and memory 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 concurrent interrupt control EEPROM interfacing and power management In addition to being configurable to interface to any two ISA patible I O functions the PCM16C00 supports logic necessary to simplify a design that uses the National DP83902A ST-NIC Ethernet Controller as one of the functions The PCM16C00 is fully pliant with PCMCIA version 2 1 and is patible with serial 4-kbit and 16-kbit EEPROMs with 8-bit and 16-bit organizations that use the MICROWIRETM protocol 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 Features PCMCIA Bus Interface pliant with multi-function extension to PCMCIA Standards 3 X PCMCIA version 2 1 configuration registers Serial EEPROM interface patible with MICROWIRE EEPROM protocol 2-kbyte on chip RAM for attribute memory which shadows 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 functions on a PCMCIA card Power management and clock control Programmable arbitration unit for PCMCIA host and two functions mon memory logic National DP83902A Ethernet LAN support logic 4 Bit direction programmable generic digital port ISA-like interface to card function 1 0 System Diagram TL F 11669 - 1 FIGURE 1-1 TRI-STATE is a registered trademark of National Semiconductor Corporation MICROWIRETM is a trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation TL F 11669 RRD-B30M75 Printed in U S A Table of Contents GENERAL DESCRIPTION AND PRODUCT FEATURES 1 0 SYSTEM...
