The ZBT (Zero Bus Turnaround) architecture eliminates the dead cycle between read and write operations — the bus stays active every clock edge, which matters when the memory controller is pipelining back-to-back transactions without wait states. ## Industrial temperature and supply tolerance The 119-ball PBGA package (14x22 mm body) routes the 36-bit parallel bus plus address and control signals. The ball pitch and layout are standard for this density class; the PCB fan-out requires at least four layers to escape the inner balls cleanly. ## Active production — sourcing posture Renesas lists the 71V3556SA166BGGI as an active product.","metaTitle":"71V3556SA166BGGI Renesas SRAM, 166 MHz, 128K x 36, 119-BGA","metaDescription":"Renesas 71V3556SA166BGGI synchronous SRAM, 4.5 Mbit, 166 MHz clock, 3.5 ns access, 128K x 36 organization, industrial temp, 119-PBGA.
