Commercial temperature grade (0°C to 70°C) limits deployment to controlled indoor environments — no extended industrial or automotive qualification on this variant.","metaTitle":"Infineon CY7C09199V-12AXC Dual-Port SRAM, 12 ns, 50 MHz","metaDescription":"Infineon CY7C09199V-12AXC synchronous dual-port SRAM, 1.152 Mbit (128K x 9), 12 ns access time, 50 MHz clock.
