At this clock rate, each read/write cycle completes in 2.5 ns — the DDR II+ architecture transfers data on both clock edges, so the effective data rate is 800 MT/s per I/O pin. For a 36-bit bus, that is 3.6 GB/s peak bandwidth into the SRAM array. The 1.7 V to 1.9 V core supply matches the low-voltage rail on modern ASICs and FPGAs. ## Package and board integration — 165-FBGA footprint The package is supplied in tray format — the bare die and substrate are moisture-sensitive; bake before reflow if the floor-life has been exceeded per J-STD-020. The 1M x 36 organization means the address bus is 20 bits wide (A0–A19) plus the 36-bit data bus. The 400 MHz clock input requires a clean 1.7–1.9 V supply with local decoupling within 5 mm of the VDD balls to keep the supply impedance below 100 mΩ at the switching frequency. ## Obsolete — sourcing reality for the CY7C1270KV18-400BZC Infineon lists this part as Obsolete. No official successor or pin-compatible replacement is recorded from the original manufacturer. The DDR II+ interface and 400 MHz clock rate are specific to this generation of synchronous SRAM — a direct drop-in is not available from the factory. For existing BOM lines, the part is sourced through independent distribution channels. Quantities are lot-specific and confirmed at RFQ.","metaTitle":"CY7C1270KV18-400BZC Infineon 36Mbit DDR II+ SRAM, 400 MHz","metaDescription":"CY7C1270KV18-400BZC Infineon 36Mbit synchronous SRAM, 400 MHz clock, 1M x 36 organization, 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, DDR II+","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1270","Memory Organization":"1M x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$53.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5ec4830e5b52d7a672cc291841e6eab9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1270KV18-400BZC/alternatives.json"},"ai":{"faq":[{"question":"What is the memory organization and clock speed of this SRAM?","answer":"The CY7C1270KV18-400BZC is organized as 1M x 36 bits (36 Mbit total) with a 400 MHz clock.
