Product details

10 ns async SRAM for legacy 5V buses

The CY7C1041D-10VXIT: The 44-SOJ package is a surface-mount J-bend footprint common in high-density memory arrays from the late-1990s through mid-2000s designs.

10 ns access time — bus timing margin

In a system with a 50 MHz bus (20 ns cycle), this leaves 10 ns of margin for address decode, board trace delay, and setup time at the controller — enough for a clean timing closure without adding wait states.

Industrial temperature range — where it runs

The 44-SOJ package's J-bend leads handle thermal cycling better than gull-wing equivalents, reducing solder-joint fatigue over thousands of power cycles.

Infineon lists the CY7C1041D-10VXIT as obsolete.

Package and storage — 44-SOJ on Tape & Reel

The 44-SOJ package is a 10.16 mm wide, 0.400 inch body, J-bend lead form. The Tape & Reel shipping medium means the parts arrive on a reel.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1041D-10VXIT?

No official pin-compatible replacement is listed by Infineon. For a new design, look for a 5V async SRAM in a 44-SOJ package with 256K x 16 organization and 10 ns or faster access time — verify the footprint and pinout against the CY7C1041D datasheet before substituting.
