The parallel interface runs at 100 MHz with a 5 ns access time, so the memory can sustain a new transaction every clock edge without wait states, provided the controller matches the ZBT protocol. ## Supply, temperature, and package The 0.5 mm pitch demands a fine-pitch soldering profile and careful PCB pad design to avoid bridging. Sourced to order against BOM quantities through independent and authorized distribution channels.","metaTitle":"71V2556S100PF 4.5Mbit ZBT SRAM, 100 MHz, 100-TQFP","metaDescription":"71V2556S100PF synchronous SRAM, 4.5Mbit (128K x 36), 5 ns access, 100 MHz clock, 3.3V supply, 100-TQFP.
