A 32-bit data bus plus 4 parity/ECC bits is the typical deployment in a 32-bit processor memory system, or as a 36-bit wide buffer in a 10/40 Gbps packet processor. The 100 MHz clock delivers a peak bandwidth of 3.6 Gbps (36 bits × 100 MHz), which matches the line rate of a Gigabit Ethernet MAC with headroom for control-plane traffic. The Infineon CY7C1371D-100AXIT is listed as Obsolete by the manufacturer. For a BOM that currently specifies this exact part, the procurement path is the independent distribution channel — last-time-buy inventory, new-old-stock, or verified surplus. Any lot received should be date-code and marking checked against Infineon's factory records, since obsolete parts see elevated remarking risk. The Tape & Reel (TR) packaging is the standard shipping form; tube or tray lots are also common in the broker channel. ## Pin-compatible family — what to look for in a replacement The base product number CY7C1371 covers multiple speed and temperature variants in the same 100-TQFP footprint. A buyer searching for a drop-in replacement should look at other CY7C1371D speed grades (e.g., -133, -167) or the CY7C1371B/C revisions — but these are also obsolete. For a new-design fit, a current-generation synchronous SRAM from the Infineon (formerly Cypress) pipeline SRAM family in a compatible 100-pin QFP package would require a PCB layout review; the NoBL bus protocol is proprietary and not matched by standard synchronous SRAMs.","metaTitle":"CY7C1371D-100AXIT Infineon NoBL SRAM, 18Mbit, 100 MHz","metaDescription":"CY7C1371D-100AXIT Infineon NoBL synchronous SRAM, 18Mbit (512K x 36), 100 MHz clock, 8.5 ns access, -40 to 85°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"NoBL™","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, SDR","Access Time":"8.5 ns","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1371","Memory Organization":"512K x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1371D-100AXIT?","answer":"A current-generation synchronous SRAM from Infineon's pipeline SRAM family in a 100-pin QFP may fit with a PCB layout review; the NoBL bus protocol is proprietary and not matched by standard synchronous SRAMs."},{"question":"What is the access time of CY7C1371D-100AXIT?","answer":"The access time is 8.5 ns.
