ATF22V10C-10PC - 10ns Flash EEPLD, 500 Gates | Microchip
MPN: ATF22V10C-10PC ✓ פעילATF22V10C-10PC סקירה
An electrically erasable programmable logic device, or EEPLD, is a programmable-logic semiconductor that stores a sum-of-products Boolean configuration in nonvolatile memory. EEPLDs occupy the position between simple fixed-function gate arrays and larger FPGAs. The ATF22V10C family provides a practical way to implement decoding, address mapping, control logic, glue logic, and other modest-complexity digital functions without using a microcontroller or a large configurable logic array.
The ATF22V10C-10PC provides a 10 ns access time, 10 macrocells, and an equivalent gate capacity of 500 gates. It operates from a nominal 5 V supply, with the commercial-temperature version rated for a maximum supply voltage of 5.25 V and an operating range from 0°C to 70°C. Flash-based configuration retention supports design revisions without package removal, while typical power dissipation can be as low as 10 µA across the broader ATF22V10C family.
The ATF22V10C uses a PAL-style architecture organized around ten macrocells. Product terms, sum-of-products logic, and a registered output path are combined to implement compact combinational or sequential control functions. Device speeds extend down to 5 ns in the family, but the ATF22V10C-10PC is specifically selected for 10 ns operation. A 5 V supply also keeps interface design compatible with conventional 5 V CMOS logic used in older control and instrumentation equipment.
Typical applications include industrial control-panel decoding, legacy peripheral-interface adapters, address and interrupt routing, glue-logic consolidation, and small state-machine implementations. Its PDIP package is particularly useful where a through-hole board requires a leaded component and where a modern FPGA package would be unnecessarily small or difficult to inspect and rework.
Designers should confirm the JEDEC fuse map, pin assignments, AC timing, and supply tolerances before replacing an older GAL22V10-family device. A DIP socket can simplify prototype changes, but exposed through-hole leads require adequate clearance from adjacent components. Configuration files and programming documentation should also be archived because the same logical design may depend on the device family's supported fuse map and test infrastructure.
This product page combines the ATF22V10C technical characteristics with package-specific alternatives, sourcing guidance, and practical considerations for evaluating a 10 ns Flash EEPLD in new or legacy 24-pin PDIP designs.

יישומים טיפוסיים
ATF22V10C-10PC מתאים עבור 6 יישוםs: Industrial Control-Panel Signal Decoding, Legacy Peripheral Interface Adapters, Address and Interrupt Routing Logic, Small State-Machine and Sequence Control, Instrumentation Signal Conditioning, Legacy Board Glue-Logic Consolidation.
Industrial Control-Panel Signal Decoding
The ATF22V10C-10PC fits control-panel decoding where several switch, selector, and interlock signals must be converted into structured logic commands. Its 10 macrocells provide enough capacity for compact sum-of-products decoding and registered outputs without introducing an FPGA or microcontroller. The 10 ns access time supports short propagation intervals between combinational conditions, while the 5 V supply aligns with conventional panel logic. Because the commercial version is rated from 0°C to 70°C, the enclosure temperature must remain within that range. Use the manufacturer's fuse map to map switch states and verify every output against the timing and fan-out requirements of the connected controller.
מומלץ
Legacy Peripheral Interface Adapters
ATF22V10C-10PC can consolidate protocol translation and signal conditioning between older 5 V peripheral devices and a controller. Ten macrocells are suitable for command decoding, address qualification, interrupt masking, and handshake generation when the design is modest in size. The electrically erasable Flash configuration allows design corrections without replacing the device, making it useful when bringing up legacy interfaces. Timing analysis should compare the 10 ns device access time with the slower edge in the overall handshake. The 24-pin PDIP package also simplifies insertion into existing through-hole prototype boards, provided the board has adequate connector and component clearance.
מומלץ
Address and Interrupt Routing Logic
The ATF22V10C-10PC is suitable for decoding address lines and generating qualified interrupt or acknowledge signals in compact control systems. A PAL-style macrocell architecture maps Boolean terms directly into logic outputs, reducing the need for separate gates and simplifying implementation of overlapping address ranges. The 10 ns access time is useful when decode signals must settle before a downstream device changes state. The device should be evaluated against the address transceiver, latch, and target-device timing rather than selected from access time alone. Verify that the implemented equations fit the ATF22V10C product-term and fuse-map limits and that the 5 V interface levels match every connected component.
מומלץ
Small State-Machine and Sequence Control
ATF22V10C-10PC can implement compact finite-state logic, step sequencing, and one-shot generation in 5 V equipment. Ten macrocells provide a practical resource limit for several registered states and their associated output conditions, while Flash-based configuration makes iteration easier during functional bring-up. The device is best suited to small state machines rather than large bus controllers or processors. Timing review should include both combinational equations and the feedback path through registered macrocells. Because the target version is specified for a 10 ns access time and 0°C to 70°C operation, confirm that both timing margin and enclosure temperature justify the commercial-grade selection.
מומלץ
Instrumentation Signal Conditioning
The ATF22V10C-10PC can implement trigger conditioning, range selection, status encoding, and interlock logic in 5 V instrumentation. Its nonvolatile Flash configuration permits repeatable programming, and the 24-pin PDIP package supports repairable through-hole assemblies where small leaded components are preferred. The 10 ns access time can help minimize decode delay in measurement sequences, but analog timing accuracy still depends on external sensors, comparators, and acquisition hardware. Keep sensitive analog routing away from high-current switching nodes and ensure the digital ground-current return does not disturb reference nodes. Confirm that each external signal remains within the ATF22V10C supply and input limits.
מומלץ
Legacy Board Glue-Logic Consolidation
ATF22V10C-10PC is well suited to consolidating scattered discrete gates into one programmable device on an older through-hole board. Ten macrocells can replace combinations of decoding gates, flip-flops, and output buffers while preserving the board's 5 V logic architecture. The 24-pin PDIP form preserves a 0.300-inch through-hole layout and eases inspection or socketed replacement. The conversion must begin with a complete audit of the original Boolean equations, asynchronous inputs, reset behavior, and unused pins. After programming the ATF22V10C, compare each new output against the original board under all relevant states. A 5 ns or 7 ns option can provide additional timing margin where mixed logic families introduce delay.

הערות תכנון
Do not treat every GAL22V10-related part as an interchangeable replacement without checking the package and fuse map. Confirm the 24-pin PDIP lead pattern, nominal 5 V supply, access-time grade, temperature range, and the supported ATF22V10C fuse map against the original design. A device with similar function but a different package suffix can require PCB changes and may not accept the original programming file. Perform a state-by-state output comparison before production use.
Reserve adequate clearance around the 0.300-inch PDIP leads and maintain the package outline specified by Microchip. Place the device away from large heat sources, relays, and high-current switching nodes to reduce temperature rise and ground bounce. Keep programming-related test pads accessible, and route sensitive clocks or measurement signals away from the connector area where long leads can increase coupling. For prototype boards, a socket can simplify device replacement and fuse-map verification.
Operate the ATF22V10C-10PC from a regulated 5 V rail that remains within its 5.25 V maximum and the stated commercial supply tolerance. Place local supply bypassing close to the device pins and keep the return path short, especially when several outputs switch simultaneously. Review the complete I/O load and dissipation at the highest expected activity. The 10 uA figure describes a low-power family condition and should not be used as the sole basis for supply sizing.
Build timing margin from the slowest relevant path rather than from the ATF22V10C access-time label alone. Include external pull-up or pull-down resistance, input rise and fall times, output loading, and any downstream setup or hold requirements. For a slower 15 ns or 20 ns replacement, verify every synchronous boundary and feedback loop. The 5 ns and 7 ns options offer additional device timing margin while retaining the same 24-PDIP organization.
