The 3.8 ns access time at a 150 MHz clock means the part can deliver a 36-bit word every clock cycle with no dead cycles between read and write turns — critical for cache-line fills, packet buffers, or DSP coefficient tables where back-to-back throughput matters more than raw density. ## Supply and temperature — where it runs Not rated for industrial or automotive under-hood use. ## Package and footprint Housed in a 100-pin TQFP (14x14 mm) — a fine-pitch surface-mount package that reflows on standard SMT lines. No exposed thermal pad, so all heat dissipates through the leads; keep the ambient airflow adequate if running sustained back-to-back bursts at 150 MHz. The 100-TQFP footprint is shared across the 71V2546 family, so a board laid out for the 150 MHz speed grade can also accept the 133 MHz or 200 MHz variants without a layout change.","metaTitle":"71V2546S150PFG 4.5Mbit Synchronous SRAM, 3.8 ns, 150 MHz","metaDescription":"Renesas 71V2546S150PFG 4.5Mbit (128K x 36) ZBT synchronous SRAM with 3.8 ns access time and 150 MHz clock.
