That margin shrinks with trace delay and clock skew, so the PCB layout engineer should keep the SRAM close to the memory controller and match trace lengths within 10 mm. The ZBT architecture eliminates the dead bus cycle between read and write transitions, which matters for back-to-back throughput in packet processing and DMA engines. The 18-bit word width (16 data bits plus 2 parity/ECC bits) is common in telecom framing and network processor applications. If the design uses a 32-bit or 64-bit memory bus, two or four of these parts populate the array. The 9Mbit total density suits moderate-sized lookup tables, packet buffers, and trace caches where SRAM speed is needed but DRAM latency is unacceptable. ## Supply and temperature range for the environment The 100-TQFP (14x14 mm) package with 0.5 mm pitch is a common footprint for mid-density SRAM, and the surface-mount assembly is straightforward for standard reflow profiles.","metaTitle":"71V65803S150PFGI Synchronous SRAM, 9Mbit, 150 MHz, 100-TQFP","metaDescription":"71V65803S150PFGI 9Mbit synchronous SRAM with 150 MHz clock, 3.8 ns access time, parallel interface, -40°C to 85°C.
