If your system runs at a lower clock rate, the margin improves proportionally. This is the spec that determines whether the SRAM can keep up with your ASIC or FPGA without wait states. ## 256K x 32 organization — why the width matters The 8Mbit memory is organized as 256K words of 32 bits each. A x32 interface is common in networking and telecom gear where a wide data bus matches the processor or packet buffer width directly — no byte-lane muxing needed. For a 32-bit CPU or a 32-bit DDR controller, this part connects without glue logic. The parallel interface uses a synchronous burst mode, so the controller must supply a clock and handle the pipeline latency. ## Commercial temperature — indoor only Not rated for automotive under-hood, outdoor base stations, or industrial enclosures without active cooling. If your application sees -40°C or +85°C, this part is not the fit — you need an industrial-temperature synchronous SRAM in the same family. Supplied in a 100-lead TQFP (14x20 mm body) — a standard fine-pitch QFP with 0.5 mm lead pitch. Surface-mount only. The 100-TQFP footprint is shared across the CY7C1368 family, so a board designed for the C-version will accept a compatible D-version without layout changes.","metaTitle":"CY7C1368C-166AXC Synchronous SRAM, 8Mbit, 166 MHz, 3.5 ns","metaDescription":"Cypress CY7C1368C-166AXC 8Mbit (256K x 32) synchronous SRAM, 166 MHz clock, 3.5 ns access, 3.135V-3.6V, 0°C-70°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":"-","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"3.5 ns","Memory Size":"8Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"166 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1368","Memory Organization":"256K x 32","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2340bba29950ed9a8121241de71117f1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1368C-166AXC/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the CY7C1368C-166AXC?","answer":"This part is obsolete from the manufacturer, but we source it through independent distribution channels.
