The core supply runs at 1.7V to 1.9V. The 165-FBGA (13x15 mm) footprint requires careful PCB layout for the 400 MHz clock and data strobes. ## Commercial temperature — indoor use only Not suitable for outdoor cabinets, factory floors, or engine bays without active climate control.","metaTitle":"Infineon CY7C1245KV18-400BZC 36Mbit QDR II+ SRAM, 400 MHz","metaDescription":"Infineon CY7C1245KV18-400BZC 36Mbit synchronous QDR II+ SRAM, 400 MHz clock, 1Mx36 organization, 165-FBGA, commercial temp.
