The 100-TQFP (14x20 mm) package is a surface-mount footprint common in mid-density memory arrays. ## 2.6 ns access time at 250 MHz — timing closure for zero-wait-state reads At a 250 MHz clock, the cycle time is 4 ns. The 2.6 ns access time leaves 1.4 ns of setup-and-hold margin before the next rising edge — enough for a typical FPGA or ASIC input register without adding a wait state. If your controller's output-hold time runs over 1 ns, you'll want to check the derating across temperature; at 70°C junction the internal timing may shift by a few hundred picoseconds. The 512K x 36 organization means the data bus is 36 bits wide, so a single chip fills a 36-bit memory word — no byte-lane gating needed. ## Commercial temperature grade — indoor equipment only It is not specified for -40°C cold start or +85°C industrial cabinets. ## 3.3V supply rail — tolerance matters The supply range is 3.135V to 3.6V, which is a ±5% window around 3.3V nominal. A 3.0V rail or a poorly regulated 3.3V rail that dips below 3.135V during transient loading will cause undefined behaviour. Infineon lists the CY7C1380KV33-250AXC as Active (current production). If you are dual-sourcing, the base product number CY7C1380 covers multiple speed and temperature grades that share the same footprint.","metaTitle":"CY7C1380KV33-250AXC Infineon 18Mbit SRAM, 250 MHz, 2.6 ns","metaDescription":"Infineon CY7C1380KV33-250AXC 18Mbit synchronous SRAM, 250 MHz clock, 2.6 ns access time, 512K x 36, 100-TQFP, 3.3V, commercial temp.
