The 167 MHz clock frequency and 3.4 ns access time set the timing budget for the memory interface: at 167 MHz the cycle time is 6 ns, so the 3.4 ns access leaves 2.6 ns of setup margin before the next clock edge, which is tight but workable with controlled impedance routing on a four-layer board. The 18-bit wide data bus (2M x 18 organization) suits applications needing parity or ECC alongside a 16-bit word — common in networking packet buffers, baseband processing, and FPGA cache memory where the extra two bits carry a byte parity or sideband tag. Supply voltage spans 3.135V to 3.6V, making it a straight drop onto a 3.3V rail with 5% tolerance. This limits the part to indoor, controlled-environment equipment — telecom central-office racks, test instrumentation, and office networking gear. Infineon (formerly Cypress) no longer manufactures this part, and there is no official last-time-buy window open. The Tape & Reel suffix (AXCT) indicates the original production packaging — any stock found in distribution will carry date codes from before the EOL announcement. The base product number CY7C1462 points to the broader NoBL family, but a direct pin-compatible drop-in replacement has not been designated. ## Package and footprint — 100-TQFP with 14x20 mm body The 100-LQFP case code is dimensionally identical — both refer to a 1.4 mm thick, 0.5 mm pitch quad flat pack with an exposed die pad. Surface-mount assembly requires a standard QFP footprint with a centre thermal pad; the pad should be stitched to a ground plane with thermal vias if the application runs sustained read/write cycles above 100 MHz.","metaTitle":"Infineon CY7C1462AV33-167AXCT NoBL SRAM, 36Mbit, 167 MHz","metaDescription":"Infineon CY7C1462AV33-167AXCT 36Mbit synchronous SRAM with NoBL architecture, 167 MHz clock, 3.4 ns access time. 100-TQFP, 0°C to 70°C.","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":"3.4 ns","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"167 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1462","Memory Organization":"2M x 18","Operating Temperature":"0°C ~ 70°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":"https://cdn.icboms.com/bdbf9409b3e2555267d0abfd02f718e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1462AV33-167AXCT?","answer":"No official replacement part number has been designated in the lifecycle record.
