The 20 ns access time means the part can serve data to a 50 MHz bus without wait states, assuming the controller's output-hold timing has a few nanoseconds of margin. At 3.3 V nominal, the supply range spans 3V to 3.6V, which covers the 3.3 V ±10% rail common in industrial and telecom designs. ## Industrial temperature grade — where it runs The 44-SOJ package (0.400\" body width) is a surface-mount footprint with J-bend leads that absorb some board flex — a consideration for high-vibration assemblies. ## 256K x 16 — why the organization matters The 256K x 16 organization matches a 16-bit data bus directly. If your processor or FPGA memory controller expects a 16-bit word, this part connects without byte-lane muxing. The write cycle time matches the access time at 20 ns, so back-to-back writes run at the same speed as reads — no dead cycles for bus turnaround.","metaTitle":"Infineon CY7C1041CV33-20VXET SRAM, 4Mbit, 20 ns","metaDescription":"Infineon CY7C1041CV33-20VXET asynchronous SRAM, 4Mbit (256K x 16), 20 ns access, 3V–3.6V, -40°C to 125°C, 44-SOJ.
