72Mbit synchronous SRAM with 200 MHz no-bus-latency pipeline
The Infineon CY7C1470V33-200AXC is a 72Mbit synchronous SDR SRAM from the NoBL™ series, organized as 2M x 36. It clocks at 200 MHz with a 3 ns access time, meaning the pipeline delivers a new data word every clock cycle without dead cycles between read and write turns — critical for high-throughput data buffers in networking or test equipment where bus-turnaround latency eats into throughput. The 3.135V–3.6V supply range and 0°C–70°C commercial temperature grade target indoor, controlled-environment gear — think base-station line cards, ATE pattern memory, or high-end FPGA configuration stores — not automotive or outdoor deployment.
Package, footprint, and reflow reality
Housed in a 100-LQFP (supplier device package 100-TQFP 14x20), this is a standard fine-pitch QFP with 0.5 mm lead pitch. The exposed pad is absent — no thermal-paste stencil step, no paddle solder joint to inspect. The 14x20 mm body sits on a standard footprint — no exotic pad geometry, no via-in-pad requirement. A single reflow profile for 0.5 mm pitch QFPs handles it; tombstoning risk is low because the leads are on all four sides and the part is symmetric.
No pin-compatible drop-in replacement from Infineon is documented; a board spin or parametric search for a 2M x 36 synchronous SRAM in a 100-pin QFP may yield alternatives from other vendors, but those are not cross-referenced here.
