This is a volatile memory part — data is retained only while power is applied — intended for high-speed buffer, cache, or working memory in embedded systems where deterministic access latency matters more than density. The 1.65 V to 2.2 V supply range is a low-voltage domain; if the rest of the board runs at 3.3 V or 1.8 V nominal, check whether level translation is needed on the address/data bus.
Industrial temperature and supply — fit for outdoor and factory-floor gear
The supply voltage tolerance from 1.65 V to 2.2 V covers the common 1.8 V rail with margin on both sides, but it will not work on a 3.3 V or 2.5 V rail without a regulator or level shifter. The 54-TSOP II package (0.400" body width, 10.16 mm) is a standard JEDEC footprint for asynchronous SRAMs of this density, so board layout reuse across density upgrades is straightforward.
Infineon lists the CY7C1061GN18-15ZSXIT as Active.
