The Infineon CY7C1346H-166AXCT is a 2 Mbit synchronous SRAM organized as 64K x 36 bits, clocked at 166 MHz with a 3.5 ns access time.
This part is officially marked Obsolete by Infineon. No last-time-buy window remains open through the factory.
Infineon does not list a direct factory replacement for this order code. 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.
The supply voltage range is 3.15 V to 3.6 V.
The CY7C1346H-166AXI is the industrial-temperature variant (-40°C to 85°C) in the same package and speed grade. Electrically and mechanically they are identical except for the temperature range; the AXCT is commercial grade (0°C to 70°C) and cannot be substituted in an industrial-temperature design without thermal risk.
