The 1.7V to 1.9V core supply aligns with the lower-voltage I/O standards common on recent FPGAs and ASICs, reducing the number of separate power rails needed on the board. ## 165-FBGA footprint — layout and supply rails The 1.7V to 1.9V VDD supply is separate from the I/O voltage (typically 1.4V or 1.8V, depending on the QDR II+ configuration), so the board needs two low-noise regulator outputs close to the SRAM. Decoupling should follow the manufacturer's recommendation: one 0.1 µF ceramic per supply pin pair, plus a bulk 10 µF on each rail.","metaTitle":"Infineon CY7C1565KV18-450BZXC QDR II+ SRAM, 72 Mbit, 450 MHz","metaDescription":"Infineon CY7C1565KV18-450BZXC synchronous SRAM, 72 Mbit (2M x 36), 450 MHz clock, 1.7V-1.9V, 165-FBGA.
