Product details

Depth and width expansion without flags

Depth and width expansion are supported via the expansion logic pins, so you can cascade multiple AM7201-25JC parts to build a deeper or wider FIFO array. There are no programmable flags (empty/full are hardwired), so the cascade control is external — typically a small CPLD or glue logic handles the handshake between stages. The 512 x 9 depth is enough for a single packet buffer in many telecom or printer applications; for deeper buffering, plan for additional FIFOs and the associated logic.

It is RoHS non-compliant, which means it contains lead in the solder finish — verify your assembly line's exemption status if you are building for EU markets.

Frequently asked questions

What are the differences between AM7201-25JC and AM7201-35JC?

The AM7201-25JC has a 25 ns access time and 28.5 MHz data rate, versus 35 ns and roughly 28 MHz for the AM7201-35JCTR. The 25 ns part draws 70 mA max supply current; the 35 ns part draws 60 mA. Both are 512 x 9 asynchronous FIFOs in the same 32-PLCC package, with identical expansion and retransmit features.

Is the AM7201-25JC RoHS compliant?

No, the AM7201-25JC is listed as RoHS non-compliant. It uses a lead-based solder finish, so check your assembly's RoHS exemption before specifying.

How to cascade multiple AM7201-25JC for deeper FIFO?

Depth and width expansion are supported via the expansion logic pins. Cascade multiple parts by connecting the expansion out of one FIFO to the expansion in of the next, with external glue logic to manage the handshake since the part has no programmable flags.
