The document describes the Quality Semiconductor QS7201 (512 x 9) and QS7202 (1K x 9) FIFOs, which utilize a dual-port RAM-based architecture to provide high-speed data communication. These devices feature independent read and write pointers, allowing for zero fall-through time and fully asynchronous operations.
These devices are useful for data communications, digital signal processing, and general data-rate management applications.
The devices have ultra-fast 10-ns flag and data access times.
An industrial temperature range of -40°C to 85°C is available with no speed loss.
