Asynchronous device; timing set by address-to-data path, not a clock edge. ## Industrial temperature range and package The 28-SOJ package is a common footprint for 256Kbit SRAMs — 0.300-inch body width, 7.62 mm, with J-bend leads for surface mounting. The SOJ footprint is compatible with many legacy board layouts; verify the land pattern against your existing design before committing the BOM.","metaTitle":"Infineon CY7C199CN-12VXI 256Kbit SRAM, 12 ns Access Time","metaDescription":"Infineon CY7C199CN-12VXI 256Kbit asynchronous SRAM, 32K x 8, 12 ns access time, -40°C to 85°C, 28-SOJ.
