Product details

What this SRAM is and where it fits

The Cypress CY7C1471V33-133AXC is a 72 Mbit synchronous SRAM organized as 2M x 36, built on the NoBL™ (No Bus Latency) architecture. It clocks at 133 MHz with a 6.5 ns access time, operating from a 3.135 V to 3.6 V supply. The part comes in a 100-lead LQFP (14x20 mm body) and is rated for the commercial temperature range of 0°C to 70°C. This is a high-throughput memory for networking equipment, telecom line cards, and high-end test instrumentation where back-to-back read-write cycles without dead cycles matter.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1471V33-133AXC?

No official second-source or pin-compatible alternate is listed in the available records. The 100-LQFP footprint and 72 Mbit density narrow the field; any replacement would need to match the 133 MHz clock, 6.5 ns access, and 3.3 V supply. We recommend checking the Cypress NoBL family for a direct-sibling order code with the same package and timing.

What does the NoBL™ series mean for this SRAM?

NoBL stands for No Bus Latency — the architecture eliminates the dead cycle normally required when switching from read to write. This lets the memory sustain back-to-back transactions at the full 133 MHz clock rate, which is critical for high-throughput applications like network packet buffers.
