ATF22V10C-10PU 概要
A simple programmable logic device is a semiconductor that stores a Boolean function as a configuration rather than implementing that function through fixed gates. The ATF22V10C belongs to the SPLD and PLD hierarchy, where product terms fuse map, macrocell, and erasable Flash configuration describe how each of its 10 logic macrocells implements registered or combinational logic. This makes the device useful as bridge logic between larger processors, FPGAs, memory devices, and industrial or communications systems.
Verified product information identifies 10 macrocells, 500 gates, a 5 V supply, a 10 ns speed designation, and a 24-pin PDIP package. The manufacturer datasheet states that the ATF22V10C family reaches speeds down to 5 ns and low typical power dissipation, while the exact ATF22V10C-10PU operating-temperature limits, current consumption, I/O counts, and AC timing values are not supplied in the verified excerpts. Those values must therefore be confirmed in the manufacturer datasheet before a new design is released.
The device architecture is appropriate for deterministic control paths, fuse-map decoding, bus-interface qualification, and small state machines. Microchip support identifies the ATF22V10C family as pin-to-pin and JEDEC-fusemap-compatible replacements for GAL22V10 devices when AC and DC behavior is compatible. Because this -10PU variant is a 10 ns speed grade, systems must preserve setup and timing margins rather than treating the number as a universal operating frequency.
Typical uses include industrial control, legacy peripheral emulation, address decoding, signal conditioning, test adapters, and compact control logic where 500 gates of programmable integration are sufficient. Mechanically, the PDIP format supports conventional through-hole assembly, prototyping, repair, and legacy boards. Surface-mounted systems should not assume that another ATF22V10C package is interchangeable because package drawings, pin availability, and assembly requirements differ.
The main design consideration is configuration compatibility. Confirm the JEDEC fuse map, pin assignments, supply voltage, timing grade, output-drive assumptions, and unused-pin treatment against the exact manufacturer datasheet. A nominal 5 V part should not be assumed suitable for 3.3 V systems without an explicit rail-level specification. For production, validate programming algorithms, erase-and-program behavior, and system timing under worst-case supply and temperature conditions.
This page combines verified manufacturer and distributor facts with explicit data gaps, package-aware replacement guidance, comparison parameters, and practical legacy-logic design notes. It is intended to accelerate component identification while preventing unverified electrical or lifecycle assumptions from entering a production BOM.

Legacy GAL22V10 Control Logic
ATF22V10C-10PU fits legacy boards that were designed around GAL22V10 fuse maps because Microchip identifies the ATF22V10C family as pin-to-pin and JEDEC-fusemap compatible. The 24-pin PDIP package preserves the original through-hole footprint, while the 10 ns grade supports designs whose logic path budget is at or above the target delay. Verify the exact GAL22V10 replacement table, AC/DC differences, programming pattern, and timing margin rather than assuming every suffix is interchangeable.
おすすめ
Industrial Address Decoding
The 10 macrocells provide a practical level of logic for address decode, chip-select generation, and control-state decoding in an older industrial controller. ATF22V10C-10PU combines that compact programmable capacity with a nominal 5 V supply and 10 ns speed grade, allowing short combinational paths close to older processor buses. Engineers should budget propagation delay together with address valid setup and peripheral select requirements, and must confirm the pinout and I/O electrical limits from the manufacturer datasheet.
おすすめ
Test and Measurement Adapters
A programmable adapter can use ATF22V10C-10PU to consolidate pin mapping, signal gating, and fixed control sequences without building a separate FPGA. Its electrically erasable Flash configuration supports repeatable logic changes during fixture development, while the PDIP package is convenient for prototype boards and through-hole repair. The 500-gate class is suitable only when the required Boolean logic and I/O fit within the 10-macrocell device; perform post-programming timing checks and protect unused inputs from floating states.
おすすめ
Peripheral Emulation and Glue Logic
ATF22V10C-10PU can bridge legacy memory, interface, and control signals where the required function fits within 10 macrocells. The nominal 5 V operation suits systems already using 5 V CMOS logic, while the 10 ns grade supports moderate-speed decoding rather than high-frequency synchronous interfaces. Use it to qualify control sequences and bus qualifiers, but validate output drive, input thresholds, and timing because those exact values are not present in the verified excerpts and must come from the official datasheet.
おすすめ
Control Panel State Machine
A compact panel controller can implement debouncing, sequencing, mode selection, and output interlocks with the ATF22V10C-10PU’s 10 macrocells. The electrically erasable configuration allows firmware or hardware revisions without changing the PCB, and the 24-pin PDIP package is practical for repairable industrial assemblies. Keep the registered-logic state rate below the available timing margin, define safe states during configuration, and include external reset behavior in the design because the device is intended for deterministic legacy control rather than complex high-density logic.
おすすめ
Legacy Interface Signal Conditioning
ATF22V10C-10PU is suitable for small interface-conditioning networks such as qualify, latch, pulse-shape, and protocol translation logic around slower legacy buses. The 10 ns grade provides a defined delay class, while nominal 5 V operation aligns with older CMOS circuitry. The device does not replace high-speed differential transceivers or modern I/O standards; use it only for compatible voltage levels, and verify propagation-delay variation, fanout, output loading, and unused-pin treatment from the manufacturer timing and electrical tables.

設計ノート
Do not treat the -10 suffix as sufficient proof of interchangeable timing. Compare the complete ordering suffix, package drawing, fuse map, pin assignments, setup and hold requirements, output loading, and AC/DC limits against the device originally on the board. Microchip states that ATF22V10C can replace GAL22V10 devices when pinout, JEDEC fuse-map compatibility, and electrical behavior are acceptable, but minor differences still require engineering review.
The 24-pin PDIP package is intended for through-hole assembly and does not match surface-mount land patterns. Preserve the original pin numbering orientation, provide adequate spacing for the programmer or socket, and route sensitive control or interface signals away from high-edge-rate switching nodes. Confirm pin names directly from the official datasheet because the supplied search excerpts identify the package but do not provide the complete numbered pin table.
Build a static and dynamic timing budget from the verified 10 ns grade rather than treating it as a universal 100 MHz operating limit. Include external device setup or hold requirements, fanout loading, macrocell configuration, and clock or control skew. The third-party listing reports 125 MHz maximum operating frequency, but that value is not supported by the supplied manufacturer excerpt and must be confirmed against the exact -10PU timing table.
Design the board for the 5 V CMOS rail and verify the exact suffix-specific voltage and temperature limits before connecting external signals. Estimated: no power calculation is possible because the verified excerpts do not provide active, quiescent, or I/O current for the ATF22V10C-10PU. Use manufacturer typical and maximum current values in the final supply sizing, and include adequate decoupling and ground-return planning around every PLD supply pin.
コンプライアンス情報
The verified excerpts do not provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable to this general-purpose logic-device classification, but no automotive qualification is claimed.
