Additional Details:

The IDT70V28L20PFI has a memory organization of 16,384 x 9 bits. It is housed in a plastic flatpack (PFI) package. The separate read and write clocks facilitate asynchronous communication, making it suitable for bridging systems that aren’t synchronized. The full, empty, and half-full flags signal critical occupancy levels, enabling efficient data management. The programmable almost-empty and almost-full flags enhance flexibility by allowing the setting of customized thresholds, suitable for proactive system monitoring. The retransmit function ensures error correction and data integrity. This FIFO is ideal for high-bandwidth applications where low power consumption and reliability are essential.
