This is a single-data-rate (SDR) synchronous SRAM, meaning it transfers one data word per clock cycle — a fit for networking buffers, cache tag stores, and DSP scratchpad memory where deterministic read/write latency matters more than double-data-rate throughput. ## Obsolete — last-time-buy window closed, sourcing through independent distribution ## 256K x 32 organization — bus width matching and address decoding The 256K x 32 memory organization means the part presents a 32-bit wide data bus and requires 18 address lines (256K = 2^18). This is a natural fit for 32-bit microcontrollers, DSPs, or FPGAs with a parallel memory controller. The 8 Mbit total density is sized for moderate-depth FIFO buffers, look-up tables, or cache tag storage. The synchronous interface registers all address, data, and control inputs on the rising edge of the 133 MHz clock, which simplifies timing closure in high-speed digital designs compared to asynchronous SRAM. ## 165-ball FBGA (13x15 mm) — layout and decoupling considerations The package is a 165-ball fine-pitch ball grid array, 13x15 mm body. This is a surface-mount BGA requiring controlled impedance routing for the 32-bit data bus and the 133 MHz clock trace. Supply decoupling should follow the manufacturer's recommendations for synchronous SRAM — typically one 0.1 µF ceramic per supply pin pair, placed as close to the balls as the board stack-up allows.","metaTitle":"Infineon CY7C1365C-133BZI 8Mbit Synchronous SRAM, 133 MHz","metaDescription":"Infineon (Cypress) CY7C1365C-133BZI 8Mbit synchronous SRAM, 133 MHz clock, 6.5 ns access, 256K x 32, 165-FBGA, -40°C to 85°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":"-","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"6.5 ns","Memory Size":"8Mbit","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":"3.135V ~ 3.63V","Base Product Number":"CY7C1365","Memory Organization":"256K x 32","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/619f44119e04cff74a2cda28fd924d0d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1365C-133BZI/alternatives.json"},"ai":{"faq":[{"question":"What is the access time of CY7C1365C-133BZI?","answer":"The access time is 6.5 ns. This is the time from clock edge to valid data output, and it sets the bus timing margin for the memory controller. At a 133 MHz clock (7.5 ns period), the 6.5 ns access leaves about 1 ns of setup margin before the next clock edge — tight, but within spec for a synchronous SRAM interface designed for this speed grade."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1365C-133BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1365C-133BZI when reusing this data.
