PCMCIA SRAM Memory Card  
SRA Series  
Card Signal Description  
Symbol  
A0 - A25  
Type  
INPUT  
Name and Function  
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. (address pins used are based on  
card density,see pinout for highest used address pin)  
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.  
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.  
DQ0 - DQ15  
CE1#, CE2#  
INPUT/OUT  
PUT  
INPUT  
OE#  
WE#  
INPUT  
INPUT  
OUTPUT ENABLE: Active low signal enabling read data from the  
memory card.  
WRITE ENABLE: Active low signal gating write data to the memory  
card.  
RDY/BSY#  
CD1#, CD2#  
OUTPUT  
OUTPUT  
READY/BUSY OUTPUT: Not used for SRAM cards  
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  
N.C.  
WRITE PROTECT: Follows hardware Write Protect Switch. When  
Switch is placed in on position, signal is pulled high (10K ohm). When  
switch is off signal is pulled low.  
PROGRAM/ERASE POWER SUPPLY: Not used for SRAM  
cards.  
VPP1, VPP2  
VCC  
GND  
CARD POWER SUPPLY: 5.0V for all internal circuitry.  
GROUND: for all internal circuitry.  
REG#  
INPUT  
ATTRIBUTE MEMORY SELECT : only used with cards built with  
optional attribute memory.  
RST  
INPUT  
RESET: Not used for SRAM cards  
WAIT#  
OUTPUT  
WAIT: This signal is pulled high internally for compatibility. No wait  
states are generated.  
BVD1, BVD2  
OUTPUT  
BATTERY VOLTAGE DETECT: Provides status of Battery  
voltage.  
BVD2 = BVD1 = Voh (battery voltage is guaranteed to retain data)  
BVD2 = Vol, BVD1 = Voh (data is valid, battery recharge required)  
BVD2 = BVD1 = Vol (data may no longer be valid, battery requires  
extended recharge)  
VS1, VS2  
OUTPUT  
VOLTAGE SENSE: Notifies the host socket of the card's VCC  
requirements. VS1 and VS2 are open to indicate a 5V, 16 bit card has  
been inserted.  
RFU  
N.C.  
RESERVED FOR FUTURE USE  
NO INTERNAL CONNECTION TO CARD: pin may be driven  
or left floating
