IDT71V30L35TFGI

The IDT71V30L35TFGI is a high-speed 3.3V 1K × 8 dual-port static RAM (SRAM) manufactured by Renesas Electronics, part of the proven 71V30 family of true dual-port memory devices. It provides two independent ports with fully asynchronous, simultaneous read/write access to a shared 8‑Kbit memory array, enabling efficient data exchange between processors. Designed for low‑power operation on a single 3.3‑volt supply, the L35 speed grade achieves an access time as fast as 35 nanoseconds. On‑chip arbitration logic, semaphore flags, and interrupt support simplify the implementation of contention‑free multiprocessor interfaces without external glue logic. The device is supplied in a surface‑mount TQFP package and includes the industrial temperature range indicator (‑I suffix), qualifying it for operation across a −40°C to +85°C ambient environment.

Dual‑port SRAM architectures are widely deployed in industrial automation controllers, military and aerospace data‑link processing, telecommunications line cards, and high‑reliability embedded computing where MCUs, DSPs, or FPGAs must share critical data with deterministic latency. Typical end uses include real‑time video buffering, interprocessor mailboxes, redundant system controllers, and cross‑domain data bridges. For procurement and sustainment, the 71V30 series represents a mature, field‑tested commodity memory line with ongoing support from Renesas; however, its longevity in the catalog can make lifecycle analysis and alternate‑source qualification prudent for programs requiring extended production or decades‑long field support. Engineers should validate temperature grade and package availability against application requirements, and consider lifetime‑buy strategies where obsolescence risk must be mitigated for aerospace, defense, or industrial infrastructure deployments.
