The CY7C0241-15AXI is a 72 Kbit dual-port asynchronous SRAM organized as 4K words by 18 bits. The 15 ns access time sets the bus turnaround window.
The 15 ns access time and write cycle time match, so back-to-back writes from one port do not stretch the cycle.
No official pin-compatible second source or direct Infineon replacement is listed in the available documentation. The CY7C0241 family shares the same footprint across speed grades (15 ns, 12 ns), but all variants are obsolete. For a new design, a current-generation dual-port SRAM from a different family would require a board layout change.
The memory is organized as 4K words by 18 bits, giving a total of 72 Kbit. The 18-bit word width accommodates a 16-bit data bus with two parity bits or an 18-bit DSP word.
