72 Mbit NoBL synchronous SRAM — what it delivers
The NoBL pipeline eliminates the dead bus cycle between read and write operations, so back-to-back transactions run at full 200 MHz clock rate without turnaround penalties. The 3 ns access time from clock rise means the data appears on the bus within one clock edge, which simplifies timing closure in high-throughput datapaths like network buffers, test equipment, and DSP memory pools. Operating from a 2.375 V to 2.625 V supply, the part is a 2.5 V nominal device. The 209-FBGA (14x22 mm) package routes 72 data lines plus address and control in a compact footprint.
209-FBGA — what the footprint demands
The 209-ball FBGA (14x22 mm) is a fine-pitch BGA. Hand-soldering is not practical; rework requires a hot-air station with a profile matched to the package mass and a stencil for paste application. The 2.5 V supply rail must be clean — a 100 nF ceramic per supply pin group is typical, with bulk capacitance sized for the transient load of 72 I/O switching at 200 MHz.
