Product details

1 Mbit asynchronous SRAM in a 44-SOJ — what you need to know

The CY7C1021CV33-15VXC: Housed in a 44-SOJ surface-mount package, this part was widely used for cache buffers, data logging, and general-purpose memory in embedded systems where fast random access and simple interfacing were required.

There is no LTB window remaining — the part is already discontinued from the factory.

44-SOJ package — rework and footprint notes

The 44-SOJ (Small Outline J-lead) package is a surface-mount form factor with J-bend leads on a 0.400-inch body width. It is a legacy package that reworks reasonably well with hot air — the J-leads are visible for inspection and touch-up, unlike a QFN or BGA. The SOJ footprint is specific to this memory family; verify the land pattern against your board layout.

Frequently asked questions

Is CY7C1021CV33-15VXC obsolete and what are the alternatives?

Yes, the CY7C1021CV33-15VXC is obsolete per Infineon's lifecycle status. No official replacement part is listed. For a drop-in alternative, the CY7C1021CV33-15VI shares the same 44-SOJ package and 15 ns speed grade but is also obsolete. A pin-compatible alternative within the same family is the CY7C1021CV33-15ZI, which uses a 44-TSOP-II package — not a direct footprint match. Evaluate the board's mechanical constraints before substituting.

What is the lead time for CY7C1021CV33-15VXC?

As an obsolete part, there is no factory lead time. Lead time is determined by available surplus inventory and is confirmed at the time of RFQ through independent distribution channels.
