PCMCIA Flash Memory Card
FLG Series
PC Card Products
Symbol
Type
Name and Function
A0 - A25
INPUT
ADDRESS INPUTS: A0 through A25 enable direct addressing of up to
64MB of memory on the card. Signal A0 is not used in word access mode.
The memory will wrap at the card density boundary (see PINOUT, note 3).
The system should not try to access memory beyond the card density.
A25 is the most significant bit. A23 – A25 are not connected.
DQ0 - DQ15
INPUT/OUTPUT
DATA INPUT/OUTPUT: DQ0 THROUGH DQ15 constitute the bi-
directional databus. DQ0 – DQ7 constitute the lower (even) byte and DQ8
– DQ15 the upper (odd) byte. DQ15 is the MSB.
CE1#, CE2#
INPUT
CARD ENABLE 1 AND 2: CE1# enables even byte accesses, CE2#
enables odd byte accesses. Multiplexing A0, CE1# and CE2# allows 8-bit
hosts to access all data on DQ0 - DQ7.
OE#
INPUT
OUTPUT ENABLE: Active low signal gating 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. This signal is not connected.
CD1#, CD2#
OUTPUT
CARD DETECT 1 and 2: Provide card insertion detection. These signals
are internally connected to ground on the card. The host shall monitor
these signals to detect card insertion (pulled-up on host side).
WP
OUTPUT
WRITE PROTECT: Write protect reflects the status of the Write Protect
switch on the memory card. WP set to high = write protected, providing
internal hardware write lockout to the Flash array.
If card does not include optional write protect switch, this signal will be
pulled low internally indicating write protect = "off".
VPP1
PROGRAM/ERASE POWER SUPPLY: Provides programming voltages
12.0V for lower byte (D0 – D7) memory components.
VPP2
PROGRAM/ERASE POWER SUPPLY: Provides programming voltages
12.0V for upper byte (D8 – D15) memory components.
VCC
CARD POWER SUPPLY: (5.0V).
GND
CARD GROUND
REG#
INPUT
ATTRIBUTE MEMORY SELECT : Active low signal, enables access to
Attribute Memory Plane, occupied by Card Information Structure and Card
Registers.
RST
N.C.
RESET: Active high signal for placing cards in Power-on default state.
This signal is not connected.
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.
RFU
RESERVED FOR FUTURE USE
N.C.
NO INTERNAL CONNECTION TO CARD: pin may be driven or left
floating
