If your controller expects a 10 ns or faster part, the 12 ns rating may eat into setup timing — check the controller's tRC and tAA requirements against the board's signal-integrity budget before committing the BOM. ## Package and supply — layout constraints The parallel interface means 16 data lines plus address and control signals; route them with matched trace lengths if the bus runs above 50 MHz to avoid skew-induced setup violations. The volatile nature means any data held during a power loss is gone — system designs must include a battery-backed supply or a supercapacitor hold-up circuit if retention across power cycles is required.","metaTitle":"CY7C1051DV33-12BAXIT Infineon SRAM, 8Mbit, 12ns, 48-FBGA","metaDescription":"CY7C1051DV33-12BAXIT is an obsolete Infineon 8Mbit asynchronous SRAM, 512K x 16, 12ns access, 3V-3.6V, -40°C to 85°C, 48-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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"12 ns","Memory Size":"8Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"48-TFBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1051","Memory Organization":"512K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-FBGA (6x8)","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a2d3039dc091136468a21062e9d4d8ef.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1051DV33-12BAXIT?","answer":"The evidence does not list an official Infineon successor order code for the CY7C1051DV33-12BAXIT. The closest pin-compatible alternative within the same family is the CY7C1051DV33-12BAXI, which shares the same 48-FBGA footprint, 8 Mbit density, 12 ns access time, and 3V-3.6V supply. The difference is the suffix: the -12BAXI is the tray/tube variant, while the -12BAXIT is the Tape & Reel variant. Both carry the same Obsolete status. For a drop-in replacement, verify the solder-ball pitch and orientation against your board layout before ordering."},{"question":"What is the memory organization of CY7C1051DV33-12BAXIT?","answer":"The memory is organized as 512K words by 16 bits (512K x 16), giving a total of 8 Mbit. The 16-bit wide data bus means it connects directly to a 16-bit memory controller; for an 8-bit bus, two read cycles are needed per word."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1051DV33-12BAXIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1051DV33-12BAXIT when reusing this data.
