For a 5V system running a 33 MHz bus (30 ns cycle), this SRAM leaves 18 ns of margin for address decode, board trace delay, and setup time at the controller — comfortable for most parallel interfaces. Write cycle time is also 12 ns (word, page mode), matching the read speed so the memory does not become the bottleneck in a balanced 32K x 8 memory map. ## 28-SOJ package — board-fit considerations The J-lead footprint is compatible with legacy SOJ-28 layouts used across the CY7C199 family.","metaTitle":"Infineon CY7C199CN-12VXA 256Kbit Async SRAM, 12 ns, SOJ-28","metaDescription":"Infineon CY7C199CN-12VXA 256Kbit (32K x 8) asynchronous SRAM, 12 ns access time, 4.5V–5.5V, -40°C to 85°C, 28-SOJ.
