Product details

Dual-port SRAM for shared-memory bridging

The CY7C146-55JXCT is a 16Kbit asynchronous dual-port SRAM organized as 2K x 8 bits, designed to let two independent bus masters read or write the same memory array without arbitration logic on the board.

5V supply and commercial temperature envelope

The supply range of 4.5V to 5.5V locks this part into legacy 5V logic domains — it will not interface directly with 3.3V or lower-voltage controllers without level translation.

Infineon lists the CY7C146-55JXCT as Obsolete.

Package footprint and layout notes

The 52-PLCC (J-Lead) package is surface-mount. The J-lead footprint requires a solder-paste stencil aperture that matches the lead width and standoff.

Frequently asked questions
