MoBL® Dual-Port Static RAM  
• Full asynchronous operation  
Features  
• Automatic power-down  
• True dual-ported memory cells that allow simultaneous  
access of the same memory location  
• Pin select for Master or Slave  
• Expandable data bus to 32 bits with Master/Slave chip  
select when using more than one device  
• 4/8/16K × 16 organization  
• High-speed access: 40 ns  
• On-chip arbitration logic  
• Ultra Low operating power  
• Semaphores included to permit software handshaking  
between ports  
— Active: ICC = 15 mA (typical) at 55 ns  
— Active: ICC = 25 mA (typical) at 40 ns  
— Standby: ISB3 = 2 µA (typical)  
• Input Read Registers and Output Drive Registers  
• INT flag for port-to-port communication  
• Separate upper-byte and lower-byte control  
• Industrial temperature ranges  
• Small footprint: Available in a 6x6 mm 100-pin  
Lead(Pb)-free vfBGA  
• Port-independent 1.8V, 2.5V, and 3.0V I/Os
