Operating from a 4.5V to 5.5V supply, it fits into 5V-tolerant parallel memory buses common in older microcontroller and DSP designs. The part is supplied in tray packaging, consistent with original manufacturing.","metaTitle":"Infineon CY7C199NL-15ZXC 256Kbit SRAM, 15 ns, 28-TSSOP","metaDescription":"Infineon CY7C199NL-15ZXC 256Kbit asynchronous SRAM, 15 ns access, 32K x 8, 4.5-5.5V, 28-TSSOP.
