PCMCIA Flash Memory Card  
FLV Series  
White Electronic Designs  
CARD SIGNAL DESCRIPTION  
Name and Function  
Symbol  
Type  
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. A25 is the most significant bit  
DQ0 - DQ15 INPUT/OUTPUT  
DATA INPUT/OUTPUT: DQ0 THROUGH DQ15 constitute the bi-directional databus. 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#  
WE#  
INPUT  
INPUT  
OUTPUT ENABLE: Active low signal gating read data from the memory card.  
WRITE ENABLE: Active low signal gating write data to the memory card.  
RDY/BSY#(*)  
OUTPUT  
READY/BUSY OUTPUT: Indicates status of internally timed erase or program algorithms. A high output indicates that  
the card is ready to accept accesses. A low output indicates that one or more devices in the memory card are busy with  
internally timed erase or write activities.  
CD1#, CD2#  
WP  
OUTPUT  
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).  
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, VPP2  
VCC  
N.C.  
PROGRAM/ERASE POWER SUPPLY: Provides programming voltages for card. Not connected for 3.3V/5V only card.  
CARD POWER SUPPLY: 5.0V for all internal circuitry  
GND  
CARD GROUND  
REG#  
INPUT  
INPUT  
ATTRIBUTE MEMORY SELECT : Active low signal, enables access to attribute memory space,occupied by the Card  
Information Structure (CIS) and Card Registers.  
RST  
RESET: Active high signal for placing card in Power-on default state. Reset can be used as a Power-Down control for  
the memory array.  
WAIT#  
BVD1, BVD2  
VS1, VS2  
OUTPUT  
OUTPUT  
OUTPUT  
WAIT#: This signal is pulled high internally for compatibility. No WAIT# states are generated.  
BATTERY VOLTAGE DETECT: These signals are pulled high to maintain SRAM card compatibility.  
VOLTAGE SENSE: Notifies the host socket of the card’s VCC requirements. VS1 and VS2 are open to indicate a 5V card  
RFU  
NC  
RESERVED FOR FUTURE USE  
NO INTERNAL CONNECTION TO CARD: pin may be driven or left floating  
(*) Signals not supported by FLV51-FLV58 (NC)
