It operates from a 1.7V to 1.9V supply and comes in a 165-ball FBGA package measuring 13x15 mm. This is a volatile memory part designed for high-throughput applications where low-latency random access and sustained bandwidth matter — think network packet buffers, switch look-aside tables, or high-end test equipment. ## 333 MHz clock — what it buys the system At 333 MHz, this DDR II SRAM delivers double-data-rate transfers on each clock edge, effectively doubling the throughput versus a single-data-rate part at the same frequency. For a 36-bit-wide bus, that works out to over 2.4 GB/s of peak bandwidth. The trade-off is tighter timing closure on the PCB — the 333 MHz clock and parallel bus need controlled impedance, matched trace lengths, and clean supply decoupling right at the BGA balls. The 1.7V to 1.9V core supply also means a dedicated regulator rail, not a shared 3.3V or 2.5V plane. The 165-ball FBGA (13x15 mm) uses a standard lead-free solder ball composition. The 13x15 mm body and 1.0 mm ball pitch need a solder paste stencil with 0.45 mm aperture diameter and a reflow profile peaking at 245°C to 260°C. Place a 4.7 µF ceramic cap per supply ball cluster within 2 mm of the BGA footprint; the via-in-pad technique with filled and capped vias keeps the solder joints flat. ## Temperature grade and deployment scope It is not qualified for industrial or automotive use where ambient temperatures exceed 70°C or fall below freezing. For new designs, it is a safe choice with normal lead times through distribution.","metaTitle":"Cypress CY7C1320KV18-333BZXC 18Mbit DDR II SRAM, 333 MHz","metaDescription":"Cypress CY7C1320KV18-333BZXC 18Mbit synchronous DDR II SRAM, 333 MHz clock, 512K x 36 organization, 165-FBGA, 0°C to 70°C.
