At 400 MHz each port delivers a 400 MT/s data rate. The QDR II+ architecture separates the read and write data buses, meaning the controller never stalls waiting for direction reversal. ## Last-time-buy — what it means for procurement Infineon has placed the CY7C1145KV18-400BZXC into Last Buy status. This is not an NRND or a gradual phase-out — it is the final ordering window before the part becomes unavailable from the factory. Any production run, repair stock, or buffer allocation that depends on this exact order code needs to be committed now. For BOM lines that cannot requalify, the independent channel is the only post-LTB source. ## Package and layout notes for the 165-FBGA The 165-ball FBGA measures 13 mm by 15 mm. The commercial temperature grade means the part is characterized only to 70°C ambient.","metaTitle":"CY7C1145KV18-400BZXC Infineon 18Mbit QDR II+ SRAM, 400 MHz","metaDescription":"Infineon CY7C1145KV18-400BZXC 18Mbit QDR II+ synchronous SRAM, 512K x 36, 400 MHz clock, 1.7V-1.9V, 165-FBGA, commercial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Last Time Buy","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1145","Memory Organization":"512K 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":"$34.7440","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/471954f57336720bdbf5b29056ab3029.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1145KV18-400BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1145KV18-400BZXC obsolete or last time buy?","answer":"Yes, Infineon has classified this part as Last Buy.
