550 MHz QDR II+ SRAM — 144 Mbit in a 165-ball FBGA
The CY7C2663KV18-550BZXI is a 144 Mbit synchronous SRAM organized as 8M x 18, built on Infineon's QDR II+ architecture. The 550 MHz clock rate defines the peak read/write throughput — at double-data-rate on both ports, the internal bandwidth supports back-to-back transactions without dead cycles, which is the defining advantage of the QDR family over traditional synchronous SRAMs. Housed in a 165-ball FBGA (15x17 mm), the package uses a fine-pitch ball array that requires controlled impedance routing on the PCB.
Industrial temperature grade and supply rails
The parallel memory interface requires matched trace lengths on the address and data lines to maintain setup/hold margins at 550 MHz. The 165-FBGA footprint's centre-ground ball assignment helps contain loop inductance in the supply path.
