Supplied on Tape & Reel, intended for automated pick-and-place assembly — not available in tray or tube per the packaging record.","metaTitle":"Infineon CY7C199C-12VXCT 256Kbit SRAM, 12 ns, 5V, 28-SOJ","metaDescription":"Infineon CY7C199C-12VXCT 256Kbit asynchronous SRAM, 12 ns access, 4.5-5.5V, 28-SOJ.
