Packaged in a 28-TSOP I (0.465\" body width, 11.80 mm), the surface-mount footprint is common for mid-density SRAMs and routes directly to a standard 28-pin TSOP layout.","metaTitle":"Infineon CY7C199CN-12ZXC 256Kbit SRAM, 12 ns, 28-TSOP I","metaDescription":"CY7C199CN-12ZXC 256Kbit asynchronous SRAM, 12 ns access, 5V supply, 28-TSOP I.
