This document introduces the features of the product released by Integrated Device Technology in 2003, including true dual-port memory cells, high-speed data access, selectable pipelined or flow-through output mode, counter enable and repeat features, dual chip enables, etc. The product operates in full synchronous mode with fast cycle time and self-timed write. It also supports separate byte controls for multiplexed bus and bus matching compatibility. Additionally, the product has industrial temperature range and supports JTAG features.
The IDT70V3599/89S provides true dual‑port memory cells that allow simultaneous access to the same address from two independent ports. It supports 128 K (or 64 K) words of 36‑bit width, high‑speed data access, and optional pipelined or flow‑through output modes.
The device operates from a 3.3 V core supply and offers selectable 3.3 V or 2.5 V I/O levels via OPT pins. It is available in 208‑pin PQFP, 208‑pin fpBGA, and 256‑pin BGA packages, and is rated for commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges.
