Product details

55 ns access time — timing margin for legacy buses

For a 5V system, this provides margin for address decoding and bus turnaround without wait states.

Obsolete — no official successor listed

The CY7C024-55AXCT is marked obsolete by Cypress (now Infineon). No direct pin-compatible replacement or recommended successor has been published for this specific speed and package variant.

It is not specified for industrial or automotive environments where the temperature swings below freezing or above 70°C.

Frequently asked questions

Is CY7C024-55AXCT obsolete?

Yes, the CY7C024-55AXCT is obsolete. Cypress has discontinued this product, and no official successor has been announced.

What is the recommended replacement for CY7C024-55AXCT?

No official replacement has been published by Cypress/Infineon for this exact speed and package variant. For a pin-compatible alternative, you would need to evaluate other 5V dual-port SRAMs in 100-TQFP from vendors like Renesas or IDT, but verify the pinout and timing against the CY7C024 datasheet.

What is the access time of CY7C024-55AXCT?

The access time is 55 ns.

Can CY7C024-55AXCT be replaced by a 3.3V dual-port SRAM?

No, not directly. This part requires a 4.5V to 5.5V supply. A 3.3V dual-port SRAM would need level translation on all I/O and a separate 5V rail, and the pinout may not match.

What is the difference between CY7C024-55AXCT and CY7C024-55AXC?

The CY7C024-55AXCT is the Tape & Reel (TR) packaging option, while the CY7C024-55AXC is typically the tray or tube version. The silicon and electrical specs are identical.
