Product details

What this 4 Mbit asynchronous SRAM brings to the bus

The Infineon CY7C1041G30-10VXI is a 4 Mbit asynchronous SRAM organized as 256K words by 16 bits. It is a parallel-interface, volatile memory part.

A 10 ns access time (address-to-data valid) is the headline rating on this part.

Package and footprint — the 44-SOJ

The CY7C1041G30-10VXI comes in a 44-SOJ package (Small Outline J-lead, 0.400" body width, 10.16 mm). The J-lead footprint is a surface-mount form factor that gives a smaller board footprint than a DIP but still allows visual inspection of solder joints. The 44-SOJ is a common pinout for 4 Mbit asynchronous SRAMs from Cypress/Infineon and ISSI, so a board layout designed for one can often take the other with no change.

Frequently asked questions

Is CY7C1041G30-10VXI RoHS compliant?

Yes, it is ROHS3 compliant, meeting the current EU restriction on hazardous substances.

What is the difference between CY7C1041G30-10VXI and CY7C1041G30-10VI?

The CY7C1041G30-10VXI is the ROHS3-compliant version. The -10VI suffix (without the 'X') was the earlier non-RoHS variant. The electrical specs — 4 Mbit, 10 ns, 44-SOJ — are identical.

What are the alternatives to CY7C1041G30-10VXI?

The closest functional second-source within the same CY7C1041 family is the CY7C1041G30-10ZSXA, which shares the same 4 Mbit, 10 ns, 256K x 16 organization but ships in a Tray instead of Tube. For extended temperature range (-40°C to 125°C), the CY7C1041G30-10BAJXE is the drop-in. If you need a different data-bus width, the CY7C1049GN30-10VXI offers 512K x 8 organization in the same 10 ns speed grade.
