72 Mbit NoBL synchronous SRAM — 250 MHz pipeline fit
The Infineon CY7C1470BV25-250AXC is a 72 Mbit synchronous SRAM organized as 2M x 36, clocked at 250 MHz with a 3 ns access time. It uses the NoBL (No Bus Latency) architecture, which eliminates the dead cycle between read and write operations — a critical feature for sustained throughput in networking equipment, telecom line cards, and high-speed DSP pipelines where back-to-back transactions are the norm. The part operates from a 2.375 V to 2.625 V supply and is specified over the commercial temperature range of 0°C to 70°C. It comes in a 100-pin LQFP package (14x20 mm body), a common footprint for high-density synchronous SRAMs. This temperature grade and supply voltage target controlled indoor environments — central offices, data centers, and lab-grade instrumentation — not extended-temperature industrial or automotive applications.
NoBL architecture — why it matters for throughput
NoBL eliminates the idle cycle between read and write, so every clock edge can carry a valid transaction.
