The Infineon CY7C1051DV33-10ZSXIT is an 8Mbit asynchronous SRAM organized as 512K x 16 bits, with a 10 ns access time and a parallel interface. It operates from a 3V to 3.6V supply, making it a direct fit for 3.3V bus systems in networking gear, telecom line cards, industrial controllers, and test equipment that need fast scratchpad or cache memory without refresh overhead.
The 10 ns access time and 10 ns write cycle time allow read or write operations at that speed.
No official replacement part number is listed in the lifecycle record. For a pin-compatible alternative, you would need to cross-reference other 8Mbit asynchronous SRAMs in the 44-TSOP II footprint with a 10 ns access time and 3.3V supply — but no direct Infineon successor is documented.
Yes, the supply range is 3V to 3.6V, so it operates directly on a 3.3V rail without a level shifter. The parallel interface is 3.3V logic-compatible.
The part is in a 44-TSOP II package (0.400" body width, 10.16 mm). The standard asynchronous SRAM pinout applies: address lines A0-A18, data lines DQ0-DQ15, chip enable, output enable, write enable, and power/ground. Pin 1 is marked on the package.
