CY7C0241AV/0251AV/036AV  
3.3V 4K/8K/16K x 16/18 Dual-Port Static RAM  
• Fully asynchronous operation  
• Automatic power-down  
• Expandable data bus to 32/36 bits or more using  
Master/Slave chip select when using more than one  
device  
• On-chip arbitration logic  
• Semaphores included to permit software handshaking  
between ports  
• INT flag for port-to-port communication  
• Separate upper-byte and lower-byte control  
• Pin select for Master or Slave  
• Commercial and industrial temperature ranges  
• Available in 100-pin TQFP  
Features  
• True dual-ported memory cells which allow  
simultaneous access of the same memory location  
• 4/8/16K × 16 organization (CY7C024AV/025AV/026AV)  
• 4/8K × 18 organization (CY7C0241AV/0251AV)  
• 16K × 18 organization (CY7C036AV)  
• 0.35-micron CMOS for optimum speed/power  
• High-speed access: 20 and 25 ns  
• Low operating power  
— Active: ICC = 115 mA (typical)  
Standby: ISB3 = 10 µA (typical)
