32K/64K x 16/18  
Dual-Port Static RAM  
Fully asynchronous operation  
Features  
Automatic power-down  
Expandable data bus to 32/36 bits or more using Mas-  
ter/Slave chip select when using more than one device  
• True Dual-Ported memory cells which allow simulta-  
neous access of the same memory location  
• 32K x 16 organization (CY7C027)  
• 64K x 16 organization (CY7C028)  
• 32K x 18 organization (CY7C037)  
• 64K x 18 organization (CY7C038)  
• 0.35-micron CMOS for optimum speed/power  
• High-speed access: 12[1]/15/20 ns  
• Low operating power  
On-chip arbitration logic  
Semaphores included to permit software handshaking  
between ports  
INT flags for port-to-port communication  
Separate upper-byte and lower-byte control  
Dual Chip Enables  
Pin select for Master or Slave  
Active: ICC = 180 mA (typical)
