ATF22V10C-10PU
ATF22V10C-10PU - 10-Macrocell 5V E2 PLD | Microchip
The Microchip Technology ATF22V10C-10PU is a 10-macrocell, electrically erasable programmable logic device operating from a nominal 5 V supply, with a 10 ns speed grade and a 24-pin through-hole PDIP package. It provides 500 programmable gates according to the Mouser product listing and combines CMOS logic with electrically erasable Flash-memory configuration technology. The device is intended for compact control, decoding, address mapping, glue logic, and legacy GAL22V10-compatible designs.
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.
