16 Mbit asynchronous SRAM in a 119-ball BGA
The part comes in a 119-ball PBGA (14x22 mm) package for surface-mount assembly. This is a volatile, fast static RAM intended for cache, buffer, or working memory in systems that need deterministic read/write timing without refresh cycles.
For a 32-bit wide data path, that translates to a theoretical peak bandwidth of 400 MB/s. The write cycle time matches the access time at 10 ns, so back-to-back writes don't incur a penalty. This matters for high-throughput applications like network packet buffers, DSP coefficient storage, or FPGA configuration memory where every nanosecond of latency adds up.
Package and layout realities
The 119-ball PBGA (14x22 mm) is a fine-pitch BGA. The 512K x 32 organisation means 32 data lines plus address and control signals — expect a dense fan-out. Plan for at least four-layer PCB with microvias or via-in-pad if the ball pitch is 0.8 mm or finer. Decoupling should follow the datasheet recommendation: a 0.1 µF ceramic per supply pin pair, placed as close to the balls as the layout allows.
For BOM qualification, the active status means no immediate supply risk from end-of-life.
