QDR II synchronous SRAM at 250 MHz
The CY7C1414KV18-250BZXCT is a Cypress 36 Mbit synchronous SRAM using the QDR II architecture, clocked at 250 MHz. The 1M x 36 organization gives a 36-bit wide data path that aligns directly with network processor and FPGA memory buses, avoiding byte-lane packing overhead. The QDR II interface uses separate read and write ports, so back-to-back reads and writes happen without dead cycles on the bus — a key advantage over standard synchronous SRAM in high-throughput applications like packet buffers and DSP pipelines.
Supply and temperature range
Core supply runs at 1.7 V to 1.9 V, matching the low-voltage I/O typical of contemporary ASICs and FPGAs. The operating temperature range is 0°C to 70°C, which is commercial grade — this part is intended for indoor, controlled-environment equipment such as telecom central-office line cards, test instrumentation, and server-class networking gear. Not rated for industrial or automotive environments without additional thermal mitigation.
Lifecycle and sourcing reality
The CY7C1414KV18-250BZXCT has an end-of-life hot status. The product status is marked Active, but the EOL flag indicates a last-time-buy notice may be active.
