The Infineon (Cypress) CY7C024-25AXC is a 64Kbit dual-port asynchronous SRAM organized as 4K x 16 bits. It gives two independent systems — or two processors on the same board — simultaneous read/write access to a shared memory block without bus-turnaround dead cycles. Typical applications include shared-memory mailboxes in multi-processor telecom line cards, video frame buffers, and data-acquisition front-ends where one port handles real-time capture and the other serves a host controller.
25 ns access time — bus timing and arbitration margin
The CY7C024-25AXC operates on a 4.5 V to 5.5 V supply. Access time is 25 ns, and write cycle time is 25 ns.
Obsolete — sourcing reality for the BOM line
The CY7C024-25AXC is marked obsolete by Infineon (Cypress). No official successor order code is published for this speed grade and package variant.
Package and temperature grade — board-fit constraints
The CY7C024-25AXC comes in a 100-LQFP (TQFP-100, 14x14 mm body) on a surface-mount tray.
