PC Card Standard Type I Form Factor
The FEA Econo Flash card series offers a low cost and
high performance eight bit linear Flash solid state storage
solution for code/data storage and embedded applications.
Packaged in PCMCIA type I or a type I half-card housing,
the FEA card series is based on Intel/Sharp Flash memory
devices: 28F0004S5 (4Mb), 28F0008S5 (8Mb) or
28F016S5 (16Mb) for 5V only applications and
28F008SA (8Mb) for 5V/12V applications. Device codes
are A7h, A6h, AAh, and A2h respectively. Systems
should be able to recognize all codes. The PC Card form
factor offers an industry standard pinout and mechanical
outline, allowing density upgrades without system design
changes.
The FEA card series is designed as a simple x8 linear
array of Flash devices. The 512KB density cards are built
with 4 Mb components (5V only), 2MB and 4MB density
options may be built with either 8Mb or 16Mb
components, and the 8MB density cards are built with
16Mb components. All components have uniform
64Kbyte sectors and use identical embedded automated
write and erase algorithms. The 8 bit design provides very
low power operation as only one component is active at a
time. The Intel Flash components provide very low
standby current in Sleep Mode.
Eight Bit Flash Memory Card (Intel based) 512KB, 1, 2, 4 and 8 MEGABYTE
SUPPORTED COMPONENTS (max 4 X):
28F008SA - max 4MB (5V Vcc/12V Vpp)

Type
Name and Function
A0 - A25
INPUT
ADDRESS INPUTS: A0 through A25 enable direct addressing of
up to 64MB of memory on the card. The memory will wrap at the
card density boundary. The system should not try to access memory
beyond the card density. The upper addresses are not connected.
DQ0 DQ15
INPUT/OUT
DATA INPUT/OUTPUT: DQ0 THROUGH DQ15 constitute the
bi-directional databus. DQ0 - DQ7 constitute the lower (even) byte.
DQ8 DQ15 are not connected. DQ7 is the MSB.
CE1#, CE2#
INPUT
CARD ENABLE 1 AND 2: CE1# enables even byte accesses,
CE2# enables odd byte accesses. CE2# is not connected.
OE#
INPUT
OUTPUT ENABLE: Active low signal enabling read data from the
memory card.
WE#
INPUT
WRITE ENABLE: Active low signal gating write data to the
memory card.
RDY/BSY#
N.C.
READY/BUSY OUTPUT: Indicates status of internally timed erase
or program algorithms. A high output indicates that the card is ready
to accept accesses. This signal is not connected.
CD1#, CD2#
OUTPUT
CARD DETECT 1 and 2: Provide card insertion detection. These
signals are connected to ground internally on the memory card. The
host socket interface circuitry shall supply 10K-ohm or larger pull-up
resistors on these signal pins.
WP
OUTPUT
WRITE PROTECT: This signal is pulled low internally. This
signifies write protect = "off " for all cases.
VPP1
PROGRAM/ERASE POWER SUPPLY: Provides programming
voltage 12.0V for lower byte (D0 D7) memory components. VPP1
is connected only for cards with 28F008SA devices, not connected
for 5V only card.
VPP2
N.C.
PROGRAM/ERASE POWER SUPPLY: Provides programming
voltage 12.0V for upper byte (D8 D15) memory components.
VPP2 is not connected
VCC
CARD POWER SUPPLY: 5.0V
GND
GROUND: for all internal circuitry.
REG#
N.C.
ATTRIBUTE MEMORY SELECT: N.C. (only used with cards
built with optional attribute memory).
RST
N.C
RESET: Active high signal for placing card in Power-on default
state. Reset can be used as a Power-Down signal for the memory
array.
WAIT#
OUTPUT
WAIT: This signal is pulled high internally for compatibility. No
wait states are generated.
BVD1, BVD2
OUTPUT
BATTERY VOLTAGE DETECT: These signals are pulled high to
maintain SRAM card compatibility.
VS1, VS2
OUTPUT
VOLTAGE SENSE: Notifies the host socket of the card's VCC
requirements. VS1 and VS2 are open to indicate a 5V card has been
inserted.
