The 500 MHz clock rate delivers back-to-back read and write operations on every rising and falling edge — effective data rate of 1 Gbps per I/O pin, making it a fit for high-bandwidth lookup tables, packet buffers, and cache in networking and telecom line cards. The parallel memory interface connects directly to a companion controller or FPGA with dedicated read and write ports — no bus-turnaround penalty between transactions. ## Package and board-fit: 165-ball FBGA The device is supplied in a 165-ball fine-pitch ball grid array (FBGA) measuring 13 x 15 mm (supplier device package 165-FBGA). The 1.0 mm ball pitch demands a multi-layer PCB with controlled impedance traces for the 500 MHz clock and data lines — a four-layer board is the practical minimum for signal integrity at these edge rates. The package is delivered in tray format, which is the standard carrier for BGA components in production programming and pick-and-place lines. The surface-mount footprint requires a solder reflow profile consistent with JEDEC J-STD-020 for moisture-sensitive devices. ## Obsolete — last-time-buy window closed Each lot is verified for authenticity and tested to the original datasheet limits before shipment. Availability is lot-specific and confirmed at RFQ — no blanket stock commitment can be made.","metaTitle":"CY7C2563KV18-500BZXI Infineon 72Mbit QDR II+ SRAM, 500 MHz","metaDescription":"CY7C2563KV18-500BZXI Infineon 72Mbit QDR II+ synchronous SRAM, 500 MHz clock, 4M x 18, -40 to 85°C, 165-FBGA.
