At 250 MHz the clock period is 4 ns. The QDR II interface uses source-synchronous clocking with a separate echo clock from the SRAM, so the PCB trace-length matching between the data, address, and clock lines needs to stay within roughly ±50 ps to avoid setup/hold violations. A board designer familiar with DDR memory routing will find the layout guidelines similar, but the QDR II's independent read and write ports simplify the bus — you never pause to turn the bus around, which eases timing closure on the controller side. No immediate supply risk, but as with any high-speed synchronous memory, securing a multi-year forecast with the distributor avoids spot-market surprises. ## Package considerations for the rework bench The 165-FBGA (15x17 mm) is a standard fine-pitch BGA with 1 mm ball pitch. For rework, the standard lead-free profile with a 240°C peak works; the part is MSL 3, so a bake at 125°C for 48 hours is required if the moisture-barrier bag has been open longer than the floor-life window. A bottom-side preheat at 150°C helps avoid cold-joint rework on the large ground plane under the BGA.","metaTitle":"CY7C1625KV18-250BZXI QDR II SRAM, 144Mbit, 250 MHz, FBGA-165","metaDescription":"Cypress CY7C1625KV18-250BZXI synchronous QDR II SRAM, 144Mbit organized 16M x 9, 250 MHz clock, 1.7V–1.9V supply, -40°C to 85°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II","Memory Size":"144Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1625","Memory Organization":"16M x 9","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$96.7000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/887d88dfd918fb0b22dd519b20ee4bb4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C1625KV18-250BZXI?","answer":"The base product number CY7C1625 covers a family of density and speed variants — a cross-reference search against other CY7C1625KV18 speed grades (e.g., -200 or -300) may yield a drop-in swap if the clock frequency requirement can flex.
