The CY7C1415KV18-300BZXC is a 36Mbit synchronous SRAM from Infineon (formerly Cypress), organized as 1M x 36 and built on QDR II architecture. The QDR II interface eliminates the read-write bus-turnaround dead cycle, allowing back-to-back transactions at the full 300 MHz clock rate — a feature designed for high-throughput applications like network processors, line cards, and telecom switches where every clock cycle of bandwidth matters. The 36-bit word width suits designs that need wide data paths without multiplexing. This part operates from a 1.7V to 1.9V supply and is rated for the commercial temperature range of 0°C to 70°C, making it a fit for indoor, temperature-controlled equipment such as base stations, routers, and test instrumentation.
300 MHz clock — what it buys you on the bus
At 300 MHz, this part operates with double-data-rate on both read and write ports.
