CARD SIGNAL DESCRIPTION  
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. A25 is the most significant bit. (address pins used are based on card density,see pinout  
for highest used address pin)  
DQ0 - DQ15  
CE1#, CE2#  
INPUT/OUTPUT  
INPUT  
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.  
OE#  
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.  
READY/BUSY OUTPUT: Not used for SRAM cards  
WE#  
INPUT  
RDY/BSY#  
CD1#, CD2#  
OUTPUT  
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  
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.  
VPP1, VPP2  
VCC  
PROGRAM/ERASE POWER SUPPLY: Not used for SRAM cards.  
CARD POWER SUPPLY: 5.0V for all internal circuitry.  
GND  
GROUND: for all internal circuitry.  
REG#  
INPUT  
ATTRIBUTE MEMORY SELECT: only used with cards built with optional attribute memory.  
RESET: Not used for SRAM cards  
RST  
INPUT  
WAIT#  
BVD1, BVD2  
OUTPUT  
OUTPUT  
WAIT: This signal is pulled high internally for compatibility. No wait states are generated.  
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
