GSI GS882ZV18/36BB/D-333/300/250/200 NBT SRAM Datasheet

The GS882ZV18/36BB/D series is a 9 Mbit synchronous static RAM that implements No Bus Turn Around (NBT) functionality, allowing zero‑wait read‑write‑read bus utilization. It operates from a 1.8 V core and I/O supply, supports frequencies from 333 MHz down to 200 MHz, and is available in 119‑bump and 165‑bump BGA packages for both 18‑bit and 36‑bit data widths. The device offers configurable pipeline or flow‑through modes, on‑chip parity, JTAG boundary‑scan, and optional linear or interleaved burst ordering.

Functional details include separate clock, chip‑enable, write‑enable, and byte‑write signals, as well as a ZZ pin for entering a low‑power sleep mode. The SRAM includes a burst address counter, ZQ pin for drive‑strength selection, and supports both commercial and industrial temperature ranges. Ordering information lists specific part numbers for each speed and package variant.
