Product details

25 ns access time — timing budget anchor

The write-cycle time is also 25 ns.

Commercial temp grade — keep it indoors

It is not rated for outdoor, under-hood, or unheated industrial enclosures.

Obsolete status — sourcing through independent channels

Infineon has marked the CY7C0241-25AXCT obsolete. The official successor is not listed in the product change notice, so replacement requires a pin-compatible dual-port SRAM from a different vendor. Existing stock in independent distribution is the primary sourcing path — each reel is date-code verified and sourced against an RFQ. For new designs, evaluate the CY7C0241-25AXI (industrial temp, still active) or a contemporary dual-port from Renesas or IDT.

Package and footprint — 100-TQFP (14x14 mm)

Supplied in a 100-pin TQFP with a 14x14 mm body. The footprint is shared with the -AXI industrial variant, so a single board layout supports both temperature grades.

Frequently asked questions

Is CY7C0241-25AXCT obsolete?

Yes, Infineon has listed the CY7C0241-25AXCT as obsolete. No last-time-buy window is active, and new production has ceased.

What is the replacement for CY7C0241-25AXCT?

Infineon has not published a direct successor for the CY7C0241-25AXCT. The industrial-temperature variant CY7C0241-25AXI is pin-compatible and still active, but verify availability. For new designs, consider a contemporary dual-port SRAM from Renesas or IDT with matching 25 ns timing and 4K x 18 organization.

CY7C0241-25AXCT vs CY7C0241-25AXI?

Both share the same 25 ns access time, 4K x 18 organization, 100-TQFP package, and pinout. The -AXI is still active; the -AXCT is obsolete.
