It operates at a 100 MHz clock frequency with a 8.5 ns access time, meaning the memory controller sees data available one cycle after the address is latched — no dead cycles on back-to-back reads or writes. The 36-bit wide data bus (512K x 36 organization) maps directly to a 32-bit processor core plus parity or ECC bits, or to a 36-bit DSP word — a common width for network processor and baseband buffer memory. The synchronous SDR interface latches address, data, and control on the rising clock edge, simplifying timing closure in high-speed digital designs. ## Supply rails and temperature grade Core supply range is 3.135 V to 3.6 V — a 3.3 V nominal rail with ±5 % tolerance covers the full operating window. The commercial temperature grade (0 °C to 70 °C) suits indoor networking equipment, test instrumentation, and server DIMM buffers where ambient stays within a conditioned environment. The exposed pad on the underside of the TQFP-100 provides a low-inductance ground return and a thermal path to the PCB copper plane — critical for the 100 MHz switching currents that can generate local hot spots if the pad is not soldered to a thermal land. Infineon lists the CY7C1371D-100AXCT as Obsolete. For a BOM line that already carries this order code, the last-time-buy window has closed. Any remaining stock is what the channel holds. If you are qualifying a replacement, the functional equivalent is a 512K x 36 synchronous SRAM in a 100-TQFP with a 3.3 V supply and 100 MHz clock — but the pinout and timing parameters differ across vendors, so a board spin is likely required.","metaTitle":"CY7C1371D-100AXCT Infineon NoBL SRAM, 18Mbit, 100 MHz","metaDescription":"CY7C1371D-100AXCT Infineon NoBL synchronous SRAM, 18Mbit (512K x 36), 100 MHz clock, 8.5 ns access, 3.135-3.6V, 0-70°C, 100-TQFP.
