This is a high-bandwidth, low-latency memory part originally designed for networking equipment — think switch fabric buffers, router lookup tables, and telecom line-card packet memory — where the DDR II interface doubles the data rate without doubling the bus clock. ## 250 MHz clock — what it buys the system At 250 MHz, the DDR II interface delivers a 500 MT/s data rate on a 36-bit-wide bus. That is enough bandwidth to feed a 10 GbE lookup engine or a mid-range packet processor without stalling. The 1M x 36 depth gives you 4 MB of working space — enough for a few thousand IPv4 route entries or a moderate packet buffer. If your design needs more depth, you would be looking at the 72 Mbit or 144 Mbit variants in this family, but the footprint changes. The 165-ball FBGA measures 13x15 mm with a fine-pitch ball array. This is not a hand-solderable part — you need a rework station with a bottom heater and a stencil for the BGA. It is not rated for the thermal cycling of an outdoor base station or an engine bay. If the board lives in a conditioned space, the temp range is fine. The CY7C1424KV18-250BZCT is officially marked obsolete. Cypress (now part of Infineon) no longer manufactures this specific speed and package variant. There is no direct pin-compatible replacement listed in the official records — the DDR II SRAM family has largely been superseded by QDR and RLDRAM architectures in new designs.","metaTitle":"CY7C1424KV18-250BZCT SRAM, 36Mbit, 250 MHz, DDR II, Obsolete","metaDescription":"Cypress CY7C1424KV18-250BZCT 36 Mbit Synchronous DDR II SRAM, 1M x 36, 250 MHz, 1.7-1.9V, 165-FBGA, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C1424KV18-250BZCT","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, DDR II","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1424","Memory Organization":"1M x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$41.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7097b135f3180a5a4b49ee6aebff0c3b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1424KV18-250BZCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1424KV18-250BZCT obsolete?","answer":"Yes, this part is officially obsolete.
