400 MHz QDR II+ SRAM for high-throughput buffer applications
The Cypress CY7C15632KV18-400BZC is a 72 Mbit synchronous SRAM using QDR II+ architecture, clocked at 400 MHz over a parallel interface. Organized as 4M x 18, it is designed for high-bandwidth data buffering in networking, telecom, and test equipment where read and write operations occur on independent ports every clock cycle. The 1.7 V to 1.9 V supply rail and commercial temperature range (0°C to 70°C) confine it to controlled indoor environments — not a fit for extended-temperature or industrial backplanes without active cooling.
