The 15 ns propagation delay sets the combinatorial address-to-output path — at this speed, the part comfortably interfaces with 50 MHz-class 5V buses and memory systems without wait-state insertion. ## 5V-only supply — fixed-rail compatibility constraint This device operates from a single 5V supply rail — there is no dual-voltage or 3.3V option. The input and output levels are 5V TTL-compatible, making it a direct drop-in for legacy 5V backplanes, memory interfaces, and glue-logic consolidation. If your system has migrated to 3.3V core logic, a level-shifter or a 3.3V-rated PLD variant is required. ## 24-SOIC wide-body — footprint and rework note Packaged in a 24-SOIC wide-body (0.295\", 7.50 mm width) — the 1.27 mm pitch is manageable with hand soldering under a microscope, but the wide body demands more PCB real estate than a narrow SOIC. Surface-mount only; no through-hole option in this suffix. The tube shipment is typical for PLDs in prototyping volume; production quantities may be sourced on tape-and-reel through the distributor channel. ## Obsolete — lifecycle reality for this BOM line Microchip has classified the ATF22V10BQ-15SI as Obsolete. For existing designs that require this exact part number, sourcing is through the surplus and broker market — independent distribution channels hold the remaining inventory. The 22V10 architecture itself is second-sourced by multiple vendors (Lattice, Cypress, Atmel legacy), but pin-compatibility and programming algorithm must be verified per alternate. A design-in of a newer 22V10-compatible PLD (e.g., the ATF22V10CQZ family) should be evaluated for new production builds.","metaTitle":"ATF22V10BQ-15SI Microchip EE PLD, 15 ns, 10 Macrocells","metaDescription":"Microchip ATF22V10BQ-15SI EE PLD, 15 ns propagation delay, 10 macrocells, 5V supply, 24-SOIC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["FPGA / CPLD & Programmable Logic"],"specifications":{"Mfr":"Microchip Technology","Speed":"15 ns","Series":"22V10","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"24-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Obsolete","Voltage - Input":"5V","lifecycle_stage":"eol_hot","Programmable Type":"EE PLD","Base Product Number":"ATF22V10B","Number of Macrocells":"10","Supplier Device Package":"24-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0efc13e4e25ffc2e80a7342f27bd4453.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATF22V10BQ-15SI/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for ATF22V10BQ-15SI?","answer":"Microchip has not published a direct successor order code for this specific variant. The 22V10 architecture is broadly second-sourced — the Microchip ATF22V10CQZ family operates at 3.3V/5V with similar macrocell count and lower power, but pin compatibility and programming algorithm must be verified against the original design file.
