CYK512K16SCCA  
MoBL®  
8-Mbit (512K x 16) Pseudo Static RAM  
Features  
Functional Description[1]  
• Advanced low-power MoBL® architecture  
• High speed: 55 ns, 70 ns  
The CYK512K16SCCA is a high-performance CMOS pseudo  
static RAM (PSRAM) organized as 512K words by 16 bits that  
supports an asynchronous memory interface. This device  
features advanced circuit design to provide ultra-low active  
current. This is ideal for providing More Battery Life™ (MoBL)  
in portable applications such as cellular telephones. The  
device can be put into standby mode reducing power  
consumption dramatically when deselected (CE1 LOW, CE2  
HIGH or both BHE and BLE are HIGH). The input/output pins  
(I/O0 through I/O15) are placed in a high-impedance state  
when: deselected (CE1 HIGH, CE2 LOW), OE is deasserted  
HIGH, or during a write operation (Chip Enabled and Write  
Enable WE LOW). Reading from the device is accomplished  
by asserting the Chip Enables (CE1 LOW and CE2 HIGH) and  
Output Enable (OE) LOW while forcing the Write Enable (WE)  
HIGH. If Byte Low Enable (BLE) is LOW, then data from the  
memory location specified by the address pins will appear on  
I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from  
memory will appear on I/O8 to I/O15. See the Truth Table for a  
complete description of read and write modes.  
• Wide voltage range: 2.7V to 3.3V  
• Typical active current: 2 mA @ f = 1 MHz  
• Typical active current: 11 mA @ f = fMAX  
• Low standby power  
• Automatic power-down when deselected

12. High-Z and Low-Z parameters are characterized and are not 100% tested.  
13. The internal write time of the memory is defined by the overlap of WE, CE = V , CE = V , BHE and/or BLE =V . All signals must be ACTIVE to initiate a write

IL  
and any of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that  
terminates write.  
14. To achieve 55-ns performance, the read access should be CE controlled. In this case t  
is the critical parameter and t is satisfied when the addresses are  
ACE  
SK  
stable prior to chip enable going active. For the 70-ns cycle, the addresses must be stable within 10 ns after the start of the read cycle.
