This part is designed for high-bandwidth applications such as network switches, telecom line cards, and base stations where the wide 36-bit word width matches the data bus of a processor or ASIC without needing external muxing. ## 167 MHz clock and 3.4 ns access — timing closure for the bus The 167 MHz clock rate and 3.4 ns access time define the read-cycle timing for the memory bus. At this speed, the SRAM can sustain back-to-back reads without wait states if the controller meets the setup and hold windows. The 3.4 ns access is the time from clock edge to data valid — budget this against the FPGA or ASIC input delay plus PCB trace flight time. A 167 MHz bus with a 6 ns period leaves about 2.6 ns for the controller to capture data after the SRAM outputs it, which is tight but workable with matched-length traces and controlled impedance. It belongs in office-environment equipment, lab instruments, or indoor telecom racks — not in an outdoor base station cabinet or an engine bay. If the design sees -40°C or +85°C, this part will not hold timing or data integrity at the extremes. Infineon lists the CY7C1386D-167AXC as obsolete. This part is no longer in factory production, so new inventory comes through independent distribution and surplus channels.","metaTitle":"CY7C1386D-167AXC Infineon 18Mbit Sync SRAM, 167 MHz, 3.4 ns","metaDescription":"Infineon CY7C1386D-167AXC 18Mbit synchronous SRAM, 512K x 36, 167 MHz clock, 3.4 ns access, 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":"-","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"3.4 ns","Memory Size":"18Mbit","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":"CY7C1386","Memory Organization":"512K x 36","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":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CY7C1386D-167AXC and CY7C1386D-167AXCT?","answer":"The difference is the shipping medium: the CY7C1386D-167AXC ships in Tray, while the CY7C1386D-167AXCT ships in Tape & Reel.
