For a system architect sizing the memory bus, that 12 ns window includes address setup, chip-select propagation, and data-out valid. On a 66 MHz bus (15 ns period), the 12 ns access leaves 3 ns of margin for PCB trace delay and buffer skew — tight but workable with careful layout. The write cycle time being identical to the read access means the controller does not need separate wait-state configurations for read versus write transactions. ## 48-ball FBGA — footprint and rework considerations The part comes in a 48-ball FBGA (8x9.5 mm) with a 0.8 mm ball pitch typical of this density class. For a procurement buyer qualifying this into a production BOM, there is no last-time-buy deadline to track. The part is the tape-and-reel ordering code (the 'T' suffix), which is the preferred format for automated pick-and-place assembly lines. The tray variant (-12BAXI) is the same silicon in a different shipping medium, so the BOM can specify either depending on the assembly house's feeder preference.","metaTitle":"Infineon CY7C1079DV33-12BAXIT 32Mbit Async SRAM, 12 ns","metaDescription":"Infineon CY7C1079DV33-12BAXIT asynchronous SRAM: 32Mbit (4M x 8), 12 ns access, 3V-3.6V, -40°C to 85°C, 48-FBGA.
