Supply range is 4.5V to 5.5V, aligning with legacy 5 V logic families and mixed-voltage systems that still carry a 5 V rail. ## 44-TSOP II footprint and sourcing posture The Tape & Reel delivery suits automated pick-and-place assembly lines. Infineon lists the CY7C1021BNL-15ZSXAT as Obsolete. ## Write cycle and timing compatibility The write cycle time matches the read access at 15 ns, so the memory can sustain back-to-back writes at the same bus rate without dead cycles. This symmetry simplifies state-machine design in cache or buffer applications where read and write latencies must match.","metaTitle":"CY7C1021BNL-15ZSXAT SRAM – 1 Mbit, 15 ns, 44-TSOP II","metaDescription":"Infineon CY7C1021BNL-15ZSXAT 1 Mbit asynchronous SRAM, 15 ns access, 64K x 16, 4.5V–5.5V, -40°C to 85°C, 44-TSOP II.
