That throughput targets high-speed data-path buffers in network switches, routers, test equipment, and compute accelerators where a conventional SRAM bus would bottleneck. ## 165-ball FBGA — footprint and layout notes The 165-ball FBGA (13 x 15 mm body) is a fine-pitch BGA that routes to a 4- or 6-layer PCB without blind vias if the escape pattern uses micro-vias on the top two layers. Place a 0.1 µF ceramic within 2 mm of each VDD/VDDQ ball pair; the datasheet's recommended 4.7 µF bulk cap per rail per quadrant prevents supply collapse during back-to-back 333 MHz bursts. The package is MSL 3 per the JEDEC standard; if the moisture barrier bag has been open longer than 168 hours at <30°C/60% RH, bake at 125°C for 48 hours before reflow. ## Industrial temperature range — deployment scope It is not characterized for extended-temp or military environments — the part has no radiation tolerance data, no MIL-STD-883 screening, and no QML certification. For avionics or downhole applications, a rad-hard or screened SRAM from the same QDR II+ family would be needed, but those are a different procurement path entirely. ## Lifecycle status — obsolete, sourced through surplus Any lot should be verified against the original datasheet for date code, marking, and functional test; counterfeit risk on obsolete high-speed SRAM is real, so a visual inspection and room-temperature functional check is a reasonable minimum before placing on a production board.","metaTitle":"Infineon CY7C2544KV18-333BZI QDR II+ SRAM, 72Mbit, 333 MHz","metaDescription":"Infineon CY7C2544KV18-333BZI is a 72Mbit synchronous QDR II+ SRAM with 333 MHz clock, 2M x 36 organization, 1.7-1.9V supply, -40 to 85°C, 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, QDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"333 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C2544","Memory Organization":"2M x 36","Operating Temperature":"-40°C ~ 85°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/22cecc698154805d99df20e9d0b2e137.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C2544KV18-333BZI obsolete and what is its replacement?","answer":"Yes, Infineon lists the CY7C2544KV18-333BZI as Obsolete. No official replacement order code has been published. For an exact pin-compatible substitute, buyers typically search the broader QDR II+ 72 Mbit, 2M x 36, 333 MHz, 165-FBGA pool from Infineon or legacy Cypress inventory — but no single direct-replacement part is guaranteed without comparing the full datasheet pinout and timing parameters."},{"question":"Can CY7C2544KV18-333BZI be used as a direct replacement for other QDR II+ SRAMs?","answer":"Only if the alternative part matches the exact 2M x 36 organization, 333 MHz clock speed, 1.7-1.9 V supply, and the same 165-ball FBGA footprint with identical ball assignments. A different density, speed grade, or supply voltage will not drop in without board and timing changes.
