It operates on a 5V supply and is intended for through-hole board designs where glue logic replacement, address decoding, or state-machine implementation is needed without a full CPLD or FPGA. ## 15 ns speed — the timing constraint The 15 ns propagation delay (tpd) sets the maximum system clock frequency this part can support in registered mode. For a typical state machine running at 50 MHz, the 15 ns delay leaves about 5 ns of timing margin after setup/hold — tight but workable. In combinatorial paths the delay is the same 15 ns pin-to-pin, so the part fits in 33 MHz bus decode or address-latching applications without wait states. The ATF22V10C-15PI is listed as Obsolete. Microchip no longer manufactures this device in the 24-pin DIP package variant. For existing BOM lines, the only sourcing channel is the independent distribution market — surplus stock, new-old-stock, or broker inventory. No official successor has been recorded for this specific order code. The 15 ns speed grade and 24-pin DIP footprint limit drop-in replacements to other 22V10 family parts from the same era, which carry their own obsolescence risk. ## 10 macrocells — logic density and fit Ten macrocells, each configurable as registered or combinatorial output, give the 22V10 architecture its flexibility. Each macrocell contains one flip-flop with programmable polarity and output-enable control. For a typical address decoder consuming 4 macrocells or a 4-state machine using 5 macrocells, the remaining 5–6 macrocells can handle output inversion or enable logic. The 10-macrocell count is the hard ceiling — a design that requires 11 registered outputs will not fit without a larger device. ## Package and supply — legacy through-hole design Housed in a 24-pin DIP (0.300 inch body width) with through-hole mounting, the ATF22V10C-15PI is a legacy footprint for socketed or wave-solder boards. The single 5V supply rail simplifies power distribution — no core or I/O voltage split.","metaTitle":"Microchip ATF22V10C-15PI 22V10 PLD, 15 ns, 10 Macrocells","metaDescription":"Microchip ATF22V10C-15PI 22V10 EE PLD, 15 ns speed, 10 macrocells, 5V, 24-pin DIP.","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":"Through Hole","Package / Case":"24-DIP (0.300\\\", 7.62mm)","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-PDIP"}},"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/ATF22V10C-15PI/alternatives.json"},"ai":{"faq":[{"question":"Is the ATF22V10C-15PI obsolete?","answer":"Yes, the ATF22V10C-15PI is marked Obsolete.

The 22V10 architecture is a standard JEDEC pinout, so other 22V10 devices from Microchip (e.g., ATF22V10CQZ) or competitors (e.g., Lattice GAL22V10) with the same 24-pin DIP footprint and 15 ns speed may work as pin-compatible substitutes, but each must be verified for programming algorithm compatibility and timing equivalence.

This is the pin-to-pin delay for combinatorial paths and the clock-to-output delay for registered paths. It supports system clock frequencies up to approximately 66 MHz in registered mode, depending on the setup time of the downstream logic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/ATF22V10C-15PI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/ATF22V10C-15PI when reusing this data.
