The Infineon CY7C144-15AXCT is a 64Kbit asynchronous dual-port SRAM organized as 8K x 8, giving two independent ports simultaneous read/write access to the same memory array.
This is a common scenario for legacy dual-port SRAMs still needed in active fielded systems.
The Tape & Reel (TR) packaging option suits automated assembly.
No official replacement order code has been published by Infineon. The part is obsolete and must be sourced from surplus or broker channels. A pin-compatible alternative within the same Cypress dual-port family may exist — check the 64-TQFP footprint and 5V supply requirement — but no specific alternate is named in the available records.
