No direct LTB window or successor order code is recorded in the lifecycle entry. For a BOM line that still calls out this exact density and speed grade, procurement now depends on independent-distribution stock — new-old-stock or surplus inventory that was manufactured before the EOL cutoff. ## 450 MHz clock — the timing-critical spec The headline rating here is the 450 MHz clock frequency. In a QDR II+ SRAM, that clock drives both read and write ports simultaneously, giving an effective data rate of 900 MHz on the I/O bus. For a system architect or FPGA designer, that 450 MHz figure sets the timing closure target for the controller interface — board trace length matching, PLL jitter budget, and setup/hold margins all tighten around this number. The 72Mbit density organized as 4M x 18 is sized for deep packet buffers in networking gear or high-speed data acquisition where the read-write turnaround penalty of a conventional SRAM would cost a cycle. ## 165-ball LBGA — layout considerations The 165-LBGA (13x15 mm body per the supplier device package) is a fine-pitch BGA. For the PCB layout engineer, that means via-in-pad or microvia fanout under the ball field, plus a full ground plane under the center of the package for thermal relief.","metaTitle":"CY7C2563KV18-450BZC QDR II+ SRAM, 72Mbit, 450 MHz, Obsolete","metaDescription":"Cypress CY7C2563KV18-450BZC synchronous QDR II+ SRAM, 72Mbit organized 4M x 18, 450 MHz clock, 165-LBGA.","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, QDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"450 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C2563","Memory Organization":"4M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f00f3e58b938cd7e8a6da25ca706e0cb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C2563KV18-450BZC obsolete?","answer":"Yes, the official lifecycle status is Obsolete.
