For a BOM line that still needs this part, the only channel is independent distribution — sourced against an RFQ from surplus or remaining distributor stock. ## 15 ns speed — what it buys on the bus The 15 ns propagation delay (tpd) is the time from input through the AND-OR array to the registered or combinatorial output. In a 5V system, this supports clock rates up to about 50-60 MHz for registered state machines, and keeps combinatorial path delays under one 74LS TTL gate-equivalent. For a legacy 5V backplane or address decoder, 15 ns is fast enough to avoid wait states with most 16- and 32-bit processors of the era. ## 10 macrocells — logic capacity check Ten macrocells, each configurable as registered or combinatorial, give roughly 200-300 gate-equivalent logic. This fits small state machines, address decoders, bus arbiters, or PAL/GAL replacement. If your design needs more than 10 registered outputs or a wider product-term array, you are looking at a larger 22V10 variant or a CPLD like the ATF150x family. ## 28-PLCC J-Lead — footprint and rework The 28-PLCC (J-Lead) package, 11.51 x 11.51 mm body, is a surface-mount legacy footprint. J-Leads are less prone to tombstoning than gull-wing, but the package body hides the solder joints — inspection requires an X-ray or a PLCC socket. For rework, a hot-air nozzle with a PLCC profile works; the J-Lead wicks solder from the pad if the stencil aperture is not matched. ## 5V-only supply — level translation needed for mixed-voltage boards This part operates on a 5V supply rail only. Input and output levels are 5V CMOS/TTL compatible. The 5V rail also means the PLD draws its full Icc from the 5V supply — factor that into the regulator budget.","metaTitle":"ATF22V10CZ-15JI EE PLD, 15 ns, 10 Macrocells, 28-PLCC","metaDescription":"ATF22V10CZ-15JI EE PLD from Microchip, 15 ns speed, 10 macrocells, 5V supply, 28-PLCC.","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":"28-LCC (J-Lead)","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":"28-PLCC (11.51x11.51)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/78837be5ad604f14389cf78ea17ff892.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATF22V10CZ-15JI/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for ATF22V10CZ-15JI?","answer":"Microchip has not published an official direct replacement for the ATF22V10CZ-15JI. The 22V10 architecture is a standard JEDEC register-rich PLD; several vendors (e.g., Lattice, Cypress) offer 22V10-compatible parts in 28-PLCC with similar 15 ns speed and 5V supply. Confirm pin-compatibility and programming support before substituting.
