It operates from a 3 V to 3.6 V supply. ## Package and mounting The 72V05L15JG supports retransmit capability, which lets you reset the internal read pointer back to the beginning of the FIFO without clearing the data. This is useful in packet-buffer applications where a transmission fails and you need to replay the same data block without reloading it from the source. The part also supports depth and width expansion, so multiple 72V05L15JG devices can be cascaded to build deeper or wider FIFO arrays — a common pattern in high-channel-count data loggers or multi-port switch buffers. Note that it does not support FWFT (First-Word Fall-Through) or programmable flags, so the flag outputs are fixed: empty, full, half-full, and the retransmit control. The asynchronous interface means no external clock is needed for the FIFO core — the read and write operations are self-timed by the control signals, which simplifies timing closure on a mixed-speed bus. ## Lifecycle and sourcing reality It is ROHS3 compliant. The active status means you can qualify it into new designs without worrying about a last-time-buy window.","metaTitle":"72V05L15JG 8Kx9 Async FIFO, 15ns, 3.3V, 32-PLCC","metaDescription":"72V05L15JG 8Kx9 asynchronous FIFO with 15ns access time, 40MHz data rate, 3.3V supply.

Do not connect it to a 5 V rail without a level translator."},{"question":"Does 72V05L15JG support retransmit capability?","answer":"Yes, it supports retransmit. The read pointer can be reset to the FIFO's start without clearing the stored data, allowing replay of the same data block."},{"question":"Can 72V05L15JG be used as a drop-in replacement for IDT72V05L15JG?","answer":"Yes, the 72V05L15JG is pin-compatible and functionally equivalent to the IDT72V05L15JG. Both are 8K x 9 asynchronous FIFOs in a 32-PLCC package with the same 15 ns access time and 3.3 V supply.

Both are 8K x 9 asynchronous FIFOs in the same 32-PLCC package and 3.3 V supply. The 15 ns version supports a higher data rate (40 MHz vs the slower variant's lower ceiling)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/72V05L15JG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/72V05L15JG when reusing this data.
