QDR II architecture delivers separate read and write data ports, eliminating bus-turnaround dead cycles that standard synchronous SRAM incurs on mixed read/write traffic. ## 250 MHz clock — timing margin and bus design The 250 MHz clock rate defines the data rate at 500 MT/s per port (double-data-rate on both read and write clocks). At this speed, board-level signal integrity becomes the limiting factor: trace-length matching within ±50 ps, controlled impedance, and minimal via stubs on the FBGA fan-out are non-negotiable. The parallel interface uses separate address and control buses for read and write, so the pin count is high (165 balls) but the protocol avoids the arbitration overhead of a shared bus. The core supply range of 1.7V to 1.9V centers on a nominal 1.8V rail. The ±0.1V tolerance is tighter than a typical 1.8V ±5% regulator output, so the power rail needs a low-noise LDO or a switching regulator with <10 mV ripple. Each supply ball should see a 100 nF ceramic within 2 mm of the ball, plus a 10 µF bulk cap per quadrant of the FBGA. The 165-ball FBGA (15x17 mm) has a 1.0 mm ball pitch — standard PCB fab can route two traces between balls, but a four-layer stackup with a dedicated power plane is recommended to keep IR drop under 30 mV across the array. Infineon (formerly Cypress) no longer manufactures this specific speed/density/temperature variant. If the board is still in design, consider migrating to a current-generation QDR II+ or QDR IV device before the layout is locked.","metaTitle":"Infineon CY7C1515AV18-250BZC QDR II SRAM, 72 Mbit, 250 MHz","metaDescription":"Infineon CY7C1515AV18-250BZC 72 Mbit QDR II synchronous SRAM, 250 MHz clock, 2M x 36 organization, 165-ball FBGA, 0°C to 70°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, QDR II","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1515","Memory Organization":"2M x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6d0f6eb85b2d9fd596d43aeddfd46285.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1515AV18-250BZC obsolete?","answer":"Yes.
