Product details

4.5 Mbit synchronous SRAM with 8 ns access

The 71V3577S80PFI is a 4.5 Mbit synchronous SRAM organized as 128K x 36 bits, with a parallel interface and a rated access time of 8 ns. Operating from a 3.135 V to 3.465 V supply, it is built for high-speed data buffering in networking, telecom, and industrial control applications where deterministic read/write latency matters.

Housed in a 100-lead TQFP (14x14 mm body) with surface-mount termination, the package footprint is standard for mid-density synchronous SRAMs and reflows with typical lead-free profiles.

Active lifecycle and compliance flag

Note that this part is marked RoHS non-compliant (contains lead in the solder finish or die attach). Verify your BOM's RoHS exemption status before committing the line.
