IDT7202LA30TDB

The Renesas IDT7202LA30TDB is a 1,024 x 9-bit CMOS asynchronous FIFO (First-In, First-Out) memory device from the 7200/7201/7202 family, manufactured for high-reliability buffering between digital systems operating at different clock rates. This low-power variant delivers a 30 ns access time and operates with fully independent read and write ports, eliminating the need for external clock synchronization. Typical features of the family include expandable depth and width configurations, status flags for empty, full, and half-full conditions, and a retransmit capability that supports data rereading without reset. The CMOS architecture ensures low dynamic and standby power consumption, while the asynchronous design simplifies interfacing in mixed-clock domains where deterministic latency is critical.

This part is housed in a ceramic dual inline package (CDIP) and carries a TDB suffix, indicating qualification over the full military temperature range (–55°C to +125°C) and adherence to stringent screening and burn-in flows appropriate for defense and aerospace systems. Typical applications span radar and sonar signal processing pipelines, military avionics data buses, satellite telemetry buffers, and secure communications gear where data integrity under thermal and mechanical stress is mandatory. Industrial automation and high-reliability data acquisition systems also leverage these FIFOs to decouple ADCs from processors. From a procurement standpoint, the IDT7202LA series is a mature CMOS product and may face diminishing supply or obsolescence; design engineers should plan for extended lead times or alternative sources. Sourcing through a specialty distributor familiar with military-grade legacy components ensures traceability, authenticity, and long-term program support.
