The QDR II architecture delivers separate read and write data ports on each clock edge — two read and two write transactions per cycle — so the 400 MHz clock yields an effective 800 MHz data rate on each port. The 1.7 V to 1.9 V core supply keeps I/O power low, but the 165-ball FBGA (15x17 mm) demands a controlled-impedance layout on the data and address lines to maintain signal integrity at those edge rates. Sourcing runs through independent distribution — quantities are lot-specific and confirmed at RFQ. Supplied in tray packaging, the part is a surface-mount 165-LBGA with a supplier device package of 165-FBGA measuring 15x17 mm.","metaTitle":"CY7C1563V18-400BZC Infineon 72Mbit QDR II SRAM, 400 MHz","metaDescription":"CY7C1563V18-400BZC Infineon 72Mbit QDR II SRAM, 400 MHz clock, 4M x 18 organization, 165-FBGA.
