PCM16C02
Configurable Multiple Function PC Card Interface Chip
General Description
National’s PCM16C02 acts as a standard interface between
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
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
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
Note PC Card refers to technology developed to the PC
Card Standards determined by the PCMCIA Standards
Committee
