This part is designed for high-bandwidth buffer and cache applications in networking, telecom, and industrial control systems where deterministic read/write latency matters — think packet buffers, line cards, or FPGA co-processing memory. The 36-bit-wide data bus maps naturally to 32-bit processors plus parity or ECC overhead without external muxing. ## 133 MHz clock and 6.5 ns access — the timing budget The 133 MHz clock frequency sets the bus cycle at 7.5 ns, and the 6.5 ns access time leaves about 1 ns of setup margin on a typical 133 MHz interface. That is tight — board trace length matching and signal integrity on the 36-bit parallel bus become critical. The synchronous pipeline eliminates the dead cycles of asynchronous SRAM, so back-to-back reads at full clock rate are possible. If your controller's timing closure budget is marginal at 133 MHz, this part will force a PCB respin; a slower 100 MHz variant in the same family might be the safer choice for legacy designs. The 165-ball FBGA (15 x 17 mm) is a fine-pitch BGA — 1.0 mm ball pitch typical for this density. Reflow profile needs a ramp rate under 2°C/s to avoid head-in-pillow defects on the larger array. Infineon lists the CY7C1441AV25-133BZXI as Obsolete.","metaTitle":"Infineon CY7C1441AV25-133BZXI 36Mbit SDR SRAM, 133 MHz","metaDescription":"CY7C1441AV25-133BZXI 36Mbit synchronous SRAM, 1M x 36, 133 MHz clock, 6.5 ns access, -40°C to 85°C, 165-FBGA.","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":"6.5 ns","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.375V ~ 2.625V","Base Product Number":"CY7C1441","Memory Organization":"1M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$59.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0b672dbe00a262d05aacc9114dd638bc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1441AV25-133BZXI/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1441AV25-133BZXI?","answer":"A pin-compatible 36 Mbit synchronous SDR SRAM from the same Cypress/Infineon family (e.g., a similar density and speed grade in the 165-FBGA footprint) may serve as a replacement, but pinout and timing must be verified against the original datasheet."},{"question":"What is the access time of CY7C1441AV25-133BZXI?","answer":"The access time is 6.5 ns, which at a 133 MHz clock (7.5 ns cycle) leaves approximately 1 ns of setup margin.
