Product details

The Infineon CY7C144-15JXC is a 64Kbit asynchronous dual-port SRAM organized as 8K x 8 bits, with a 15 ns access time that sets the window for read and write cycles on a shared memory bus. The dual-port architecture gives two independent controllers simultaneous access to the same memory array, eliminating the arbitration overhead of a multiplexed single-port design.

5V-only supply — check your rail before committing

If your design runs on 3.3V or lower, you will need level translators on address, data, and control lines.

The CY7C144-15JXC is officially obsolete per the manufacturer. Sourcing is through independent distribution channels, where inventory is fixed and finite.

Package and footprint — 68-PLCC

Housed in a 68-lead PLCC (J-Lead) package with a body size of 24.23 mm x 24.23 mm. The J-lead footprint is surface-mount but requires a PLCC socket or a reflow profile suited to the lead geometry.

Frequently asked questions

Is CY7C144-15JXC obsolete?

Yes, the manufacturer lists CY7C144-15JXC as obsolete. It is no longer in production and has no active last-time-buy window. Sourcing is limited to existing inventory in the independent channel.

What is the replacement for CY7C144-15JXC?

The manufacturer has not published an official successor for CY7C144-15JXC. For a pin-compatible drop-in, evaluate the CY7C144-15JXC's own family (CY7C144 base number) — some variants may still be active. Contact us with your requirements for cross-reference assistance.

What is the access time of CY7C144-15JXC?

The write cycle time (word, page) is also 15 ns.
