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.
