The 72V02L15JG from the IDT 72V series is a 1K x 9 asynchronous FIFO. Its 15 ns access time pairs with a 40 MHz data rate on 3 V to 3.6 V logic interfaces.
Retransmit and expansion — flexible buffer control
Retransmit capability allows resetting the read pointer to the beginning of the stored data without a full FIFO reset — useful in packet retry or error-recovery sequences. Expansion support in depth and width means multiple 72V02L15JG devices can cascade for larger buffers (deeper queues or wider words) using external logic. Note that FWFT (First-Word Fall-Through) and programmable flags are not supported on this asynchronous variant; flag timing is based on empty/full status outputs.
ROHS3 compliant per the lifecycle record.
