Product details

Sourcing an obsolete SRAM — what to expect

Cypress no longer manufactures it, so new-stock procurement moves through independent distribution and surplus inventory. The 44-SOJ package is a legacy JEDEC footprint — verify board-level compatibility if you are retrofitting an existing design.

It belongs in office equipment, telecom indoor racks, or benchtop instrumentation — not in a motor drive cabinet or an outdoor enclosure where the ambient can dip below freezing.

Package note for the rework bench

The 44-SOJ (Small Outline J-lead) package is a surface-mount form factor with J-shaped leads on 1.27 mm pitch. It is a through-hole-like solder joint but reflow-compatible. The Tube shipping medium means the parts arrive in anti-static tubes — plan for tube feeders or hand placement if you are populating a prototype run.

Frequently asked questions

Is CY7C1041CV33-15VC obsolete or EOL?

Yes, the product status is Obsolete. Cypress has discontinued production. New requirements must be filled from surplus or broker channels.

What is the replacement or equivalent for CY7C1041CV33-15VC?

No official replacement is recorded. A functionally equivalent 4Mbit async SRAM with 15 ns access time in a 44-pin SOJ package would need to be qualified for timing and footprint compatibility — no drop-in is guaranteed without a board-level review.

Does CY7C1041CV33-15VC work with 3.3V supply only?

Yes, the supply range is 3.0 V to 3.6 V, which is 3.3 V nominal. It is not 5 V tolerant — do not connect to a 5 V rail.
