PCMCIA SRAM Memory Card  
SRV20 Series  
SRAM Memory Card 2MB through 16MB  
General Description  
Features  
High Performance SRAM memory Card  
The WEDC SRAM Series (SRV20) memory cards  
offer a high performance nonvolatile storage solution  
for code and data storage, disk caching, and write  
intensive mobile and embedded applications.  
• Universal 3.3 to 5 Volt Supply allows for wider  
compatibility between systems.  
• Fast Access times: 150ns @ 3.3V – 5V  
• x8/x16 PCMCIA standard interface  
Packaged in PCMCIA type I or type II housing (type  
II for cards with extended battery backup time), the  
WEDC SRAM SRV20 series is based on high  
density and super low power SRAM memory  
devices, providing densities from 2MBytes to  
16MBytes.  
• Low Power CMOS technology provides very low  
power and reliable data retention characteristics  
- standby current < 100µA typical  
• Rechargeable Lithium battery with recharge circuitry  
- eliminates the need for replaceable batteries  
- standby current during recharge typically < 2mA  
- battery backup time  
• 18 months - type I card  
• 40 months - type II card  
The SRV20 series of SRAM memory cards has a  
universal wide power supply (3V to 5V) and operates  
at speeds as high as 150ns. The cards are based on  
advanced CMOS technology providing very low  
power and reliable data retention characteristics.  
WEDC’s SRAM cards contain a rechargeable  
lithium battery and recharge circuitry, eliminating the  
need for replaceable batteries found in many SRAM  
cards.  
typical based on 4MB  
• Unlimited write cycles, no endurance issues  
• Optional Features:  
• 2KB EEPROM attribute memory containing CIS  
• Optional Hardware Write Protect switch  
WEDC’s standard cards are shipped with WEDC’s  
SRAM Logo. Cards are also available with blank  
housings (no Logo). The blank housings are available  
in both a recessed (for label) and flat housing. Please  
contact WEDC sales representative for further  
information on Custom artwork.

3. BVD1 is an open drain output with a 10K ohm internal pull-up resistor.  
4. The A23 Address line for 16MB capacities is also used for 12MB cards.  
5. VS1 is grounded and VS2 is open to indicate a 3.3V/5V card, with a 5V key, has been inserted.

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)  
DQ0 - DQ15  
CE1#, CE2#  
INPUT/OUT DATA INPUT/OUTPUT: DQ0 THROUGH DQ15 constitute the  
PU T  
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.

2. Control Signals: CE1#, CE2#, OE#, WE#, REG#.  
3. Typical: VCC = 5V, T = +25C.  
4. ICCS includes battery recharge current. Value depends on battery discharge level. ICCS min is specified for fully  
charged battery. ICCS typical value is specified for battery discharge to 2.7V. ICCS max is specified for a fully  
discharged battery (0V). Battery will recharge to 1.5V in 20 sec.  
5. Values are the same for byte and word wide modes for all card densities.  
6. Exceptions: Leakage currents on CE1#, CE2#, OE#, REG# and WE# will be < 500 µA when VIN = GND due to
