It provides two independent ports with separate control, address, and I/O lines, allowing simultaneous access from two bus masters — a common architecture for mailbox or buffer memory in multi-processor systems. The 12 ns access time and 50 MHz clock set the timing budget for arbitration logic and bus turn-around. At 3.3 V supply, the part operates within the standard 3.0–3.6 V range used by many FPGAs and ASICs. ## 100-TQFP footprint — reflow and layout considerations The 100-TQFP (14x14 mm) package has a 0.5 mm pitch. This demands a controlled reflow profile — check the MSL rating before placing it; a high MSL level without a pre-bake risks popcorning in the oven. For industrial or automotive use, a wider-temperature sibling would be needed. Infineon lists the CY7C09189V-12AXC as Obsolete. Production has ended; the only supply channel is the independent distribution market. The tray package is the standard delivery format — verify the reel or tube requirement if your pick-and-place expects tape.","metaTitle":"CY7C09189V-12AXC 576Kbit Dual-Port SRAM, 12 ns, Obsolete","metaDescription":"CY7C09189V-12AXC 576Kbit dual-port synchronous SRAM, 64K x 9, 12 ns access, 50 MHz clock, 100-TQFP.
