Lifecycle

Current status: This CY7C144E family has been widely used and remains available from Infineon/Cypress channels; availability can vary by speed grade and package. For the most up-to-date lifecycle status, please check with Y-IC.

Equivalent/alternative models (same family, verify pinout and speed before use):

- CY7C144E-15AXC (Tray packaging, same speed grade and functionality)

- CY7C144E-20AXCT (20 ns speed grade, Tape & Reel)

- CY7C144E-20AXC (20 ns speed grade, Tray)

Functionally comparable devices from other vendors (not guaranteed drop-in; verify pin compatibility and timing):

- Renesas/IDT 70V24 or 70V24L series (64 Kb dual-port SRAM, 5 V families)

- ISSI dual-port SRAM families (e.g., IS65/IS61 series at similar densities)

If you need a different speed, package, or a pin-compatible drop-in and do not see it listed, please contact our sales team via the Y-IC website for detailed cross-reference support.
