Product details

MoBL® 4Mbit SRAM — 45 ns parallel access for low-power bus designs

The Infineon CY621472E30LL-45ZSXIT is a 4Mbit MoBL® SRAM organized as 256K x 16, with a 45 ns access time and a 2.2 V supply. It is a volatile, parallel-interface memory in a 44-pin TSOP II package, rated for -40°C to 85°C industrial temperature.

Sourcing — quoted to order through independent distribution

This SRAM is sourced through independent distribution channels. Pricing and lead time are confirmed at quote time against an RFQ.

Frequently asked questions

Does CY621472E30LL-45ZSXIT come in tape and reel packaging?

Yes, the ZXIT suffix indicates Tape & Reel packaging, suitable for automated assembly.

What is the difference between CY621472E30LL-45ZSXIT and CY621472E30LL-45ZXIT?

The ZSXIT suffix includes Tape & Reel packaging; the ZXIT variant typically ships in tray or tube. Functionally they are identical — same 45 ns access time, 2.2 V supply, and 256K x 16 organization.

Is CY621472E30LL-45ZSXIT RoHS compliant and lead-free?

Yes, the ZXIT suffix designates RoHS compliance and lead-free (Pb-free) finish.

Is CY621472E30LL-45ZSXIT a direct replacement for IS61WV25616BLL?

Both are 256K x 16 SRAMs in similar TSOP packages, but the IS61WV25616BLL typically operates at 2.4 V to 3.6 V, while this part runs at 2.2 V. Verify the supply rail and timing before substituting — the 45 ns access time matches many 55 ns or 45 ns grades, but check the specific ISSI datasheet for pin compatibility.
