PCM16C010
Configurable PC Card Interface Chip
Note, PC Card refers to technology developed to the PC
Card Standards determined by the PCMCIA Standards
Committee.
General Description
National’s PCM16C010 acts as a standard interface be-
tween the PC Card Host bus and local card busses found on
I/O and memory PC Cards. This device allows the card de-
signer to focus on the design of the I/O functions while
providing a one-chip solution for I/O memory window con-
trol, EEPROM interfacing, and power management.
Features
Y
PC Card bus interface
Y
PC Card Standard configuration registers
Y
100 pin TQFP package
The PCM16C010 provides a PC Card interface for any ISA
like function which allows it to be placed on a PC Card.
Y
Configurable as NAND Flash (NM29N16) interface
Y
Serial EEPROM Interface compatible with
MICROWIRETM EEPROM protocol
In addition, the PCM16C010 provides the capability to con-
figure the function as a NAND Flash (NM29N16) interface;
supporting all of the necessary control signals required to
handshake with NAND Flash (NM29N16) memory devices.
Y
1-kbyte on chip RAM for attribute memory which shad-
ows the CIS and is used for loading static registers
Y
Address decoding and control for I/O functions
The PCM16C010 is fully compliant with the PC Card Stan-
dard. This IC allows the system software to setup an I/O
decode window and provides the Attribute memory decode
control that allow attribute read and write data transfers.
Y
Power management and clock control
Y
Common memory logic for common memory devices in-
cluding NOR Flash devices
