CY7C1515KV18-300BZXI

The CY7C1515KV18-300BZXI from Cypress Semiconductor is a 72-Mbit Quad Data Rate II (QDR II) Synchronous SRAM organized as 2M words by 36 bits, delivering high-speed, low-latency memory performance for demanding data path architectures. This device operates from a single 1.8V core and I/O supply, with a clock frequency of 300 MHz that translates to 600 Mega-transfers per second per I/O pin via its double-data-rate signaling. It features independent read and write ports with dedicated clock inputs, enabling simultaneous read and write operations that eliminate bus contention in high-throughput designs. Housed in a 165-ball fine-pitch BGA package, the component supports compact board layouts and robust signal integrity. The industrial temperature range denoted by the “I” suffix ensures reliable operation across extended thermal environments.

Typical deployments include network routers and switches, telecommunications line cards, and base station infrastructure where deterministic access times and high random-transaction rates are critical. In aerospace and defense systems, it serves in radar processing, electronic warfare, and software-defined radio platforms that require non-volatile-like reliability without the endurance limitations of NAND flash. Procurement considerations for this QDR II SRAM include managing lifecycle transitions, as high-speed SRAM families can face extended lead times or obsolescence risks as process nodes mature. The industrial-grade rating broadens its suitability for outdoor or ruggedized equipment, and sourcing through authorized channels is essential to ensure traceability and full electrical compliance against counterfeits.
