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.
