For a microcontroller or FPGA running a parallel memory interface at moderate clock speeds, this provides comfortable timing margin without needing fast-page or synchronous modes. The write cycle time matches at 70 ns, so read and write cycles are symmetric — useful for legacy 8-bit processor designs where the bus controller expects a fixed cycle window. ## RoHS non-compliance — a sourcing constraint This part is marked RoHS non-compliant. For designs targeting EU RoHS or similar environmental directives, this is a showstopper unless an exemption applies. If your project needs a RoHS-compliant 256Kbit asynchronous SRAM in the same footprint, consider the CY7C1399BN-12VXI family — though that part runs at 12 ns access and 3.0V nominal, so verify timing and supply margin before substituting. ## Sourcing and availability No immediate LTB risk given its active status, but the RoHS restriction means supply may tighten as OEMs shift to compliant alternatives. For dual-sourcing resilience, the CY7C1399BN-12VXI is a functional peer in the same 32K x 8 organisation, though at a faster 12 ns access and 3.0V nominal supply — check your bus timing and voltage margin before qualifying it as a drop-in.","metaTitle":"CY62256VLL-70ZRI MoBL SRAM, 256Kbit, 70 ns, 28-TSOP I","metaDescription":"Infineon CY62256VLL-70ZRI MoBL asynchronous SRAM, 256Kbit (32K x 8), 70 ns access, 2.7V-3.6V, -40°C to 85°C, 28-TSOP I.
