PCM16C00
Configurable Multiple Function PCMCIA Interface Chip
General Description
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
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^TM 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
