The 3.5 ns access time from clock edge to data valid gives the FPGA or ASIC a tight but workable setup window; budget your PCB trace delay and input capacitance to avoid hold-time violations on the data bus. The NoBL™ (No Bus Latency) architecture allows a new read or write to start on every clock cycle without inserting dead cycles for bus turnaround. This is the key difference from a standard synchronous SRAM: you get full 166 MHz throughput on mixed read/write traffic, not just sequential bursts. ## Package and temperature grade — design-in checklist The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. The supplier device package is 165-FBGA (13x15). Plan for a multi-layer PCB with microvias if routing density demands it.
