That 15 ns sets the upper bound on the clock frequency in registered mode and the address-access window in asynchronous decode applications — for a 33 MHz bus, the 15 ns tPD leaves roughly 15 ns of setup margin before the next clock edge, enough for most glue-logic paths without pipeline registers. ## 10 macrocells — logic capacity for PAL/GAL replacement Ten macrocells, each configurable as registered or combinatorial, give this PLD the density to replace a handful of 20-pin PALs or GALs in a single 24-TSSOP package. Microchip lists the ATF22V10CQ-15XC as Obsolete. For a legacy BOM line, the only channel is surplus or broker inventory — date-code and marking verification becomes the critical step. ## 24-TSSOP footprint — rework and layout notes The fine pitch demands a controlled hot-air rework profile — the recommended peak temperature for lead-free reflow is 260 °C. In layout, place a 0.1 µF decoupling cap within 5 mm of each VCC pin; the 5 V supply rail should be wide enough to handle the transient current during registered output switching.","metaTitle":"Microchip ATF22V10CQ-15XC EE PLD, 15 ns, 10 Macrocells","metaDescription":"ATF22V10CQ-15XC is a 5V EE PLD with 15 ns propagation delay, 10 macrocells in a 24-TSSOP 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-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","Voltage - Input":"5V","lifecycle_stage":"eol_hot","Programmable Type":"EE PLD","Base Product Number":"ATF22V10C","Number of Macrocells":"10","Supplier Device Package":"24-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5ae1a1706088582335c7a2d9d815b287.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATF22V10CQ-15XC/alternatives.json"},"ai":{"faq":[{"question":"Is ATF22V10CQ-15XC obsolete and what are the replacement options?","answer":"Yes, the ATF22V10CQ-15XC is listed as Obsolete by Microchip. No official successor or pin-compatible replacement is recorded. For an existing design, the closest functional alternative is another 22V10-family PLD from the same series (e.g., ATF22V10C series in a compatible package), but pin compatibility and speed grade must be verified against the original BOM.
