Any pin-compatible substitute must match the 100-pin TQFP footprint, 64K x 36 organization, 3.15 V to 3.6 V supply, and synchronous SDR interface. Check the CY7C1346 family for other speed or temperature variants that may fit."},{"question":"What is the voltage supply range of CY7C1346H-166AXCT?","answer":"The supply voltage range is 3.15 V to 3.6 V."},{"question":"Is CY7C1346H-166AXCT compatible with CY7C1346H-166AXI?","answer":"The CY7C1346H-166AXI is the industrial-temperature variant (-40°C to 85°C) in the same package and speed grade.
