IDT70V27L20PFGI

The IDT70V27L20PFGI is a Renesas Electronics high-speed dual-port static RAM organized as 32K x 16 bits and powered from a single 3.3V supply. It belongs to the 70V27 family and provides true simultaneous access from two independent ports with on-chip arbitration logic and busy/interrupt signaling for contention management. The –20 speed grade indicates a typical access time of 20 ns, supporting fast data transfer between asynchronous or synchronous processors without external wait states. This device is housed in a 100-lead TQFP (PF) package with industrial temperature range and lead-free (green) plating, making it suitable for dense board layouts and extended environmental requirements.

Typical end uses for this dual-port SRAM include high-reliability embedded systems where processors, DSPs, or FPGAs must exchange shared data buffers, such as mission computers, radar and signal processing cards, avionics line replaceable units, and industrial automation controllers. The architecture eliminates the need for complex DMA chaining by serving as a mailbox memory or cache-coherent scratchpad in multi-master designs. From a procurement standpoint, the industrial grade and Renesas continuity of supply help mitigate obsolescence risk for long-lifecycle programs; however, designers should verify the product’s active status and lifecycle policy, as dual‑port SRAMs are increasingly niche. The JEDEC-standard TQFP package and full industrial temperature rating simplify second‑sourcing evaluations for defense, aerospace, and industrial OEMs requiring extended-temperature operation and RoHS‑compliant materials.
