ATF22V10C-7PC - 7ns 500-Gate Flash PLD | Microchip Technology
料号： ATF22V10C-7PC ✓ 量产中ATF22V10C-7PC 概述
An EEPLD is a programmable logic device that stores a logic configuration in nonvolatile memory. The device sits within the hierarchy of programmable logic devices, including simple PLDs, complex PLDs, FPGAs, and CPLDs. Unlike a mask-programmed logic array, the ATF22V10C-7PC can be erased and reprogrammed, allowing the same board design to support multiple logic configurations, design revisions, or field updates.
The principal performance characteristics are a 7 ns device speed, 500 equivalent gates, 10 macrocells, 5 V operation, and nonvolatile Flash-backed configuration storage. The ATF22V10C family also includes speed options down to 5 ns, and Microchip documents power dissipation as low as 10 μA typical for the family. The commercially graded -7PC ordering code identifies the 7 ns variant in the 24-pin PDIP package.
Architecturally, the device implements sum-of-products logic through a fuse-map-compatible PLD arrangement. Microchip identifies the ATF22V10C, ATF22V10CQ, and ATF22V10CQZ as suitable replacements for the GAL22V10 because they are pin-to-pin and JEDEC fuse-map compatible. Electrical and timing characteristics should still be compared against the original GAL22V10 datasheet before substituting them into an existing design.
Typical uses include industrial control signal decoding, legacy peripheral interfacing, custom logic functions, product routing, test-fixture control, and small control systems where a compact 10-macrocell PLD is more practical than a larger FPGA. Its nonvolatile Flash configuration also avoids loading the programming pattern into volatile memory after each power-up.
Designers should preserve the published 24-pin footprint, supply requirements, timing limits, and output-drive constraints when replacing a GAL22V10 or another compatible PLD. Because the verified source set does not provide a complete pin list, electrical limits, or detailed AC timing tables, those values must be confirmed in the manufacturer datasheet before layout release or production use.
This page consolidates verified Microchip and distributor information, identifies same-package replacement candidates, and separates confirmed parameters from data that still requires datasheet review. This added context helps engineers compare ATF22V10C-7PC with legacy PAL/GAL logic without mistaking package similarity for guaranteed system compatibility.

典型应用
ATF22V10C-7PC 适用于 6 应用s: Industrial Control Signal Decoding, Legacy GAL22V10 Migration, Peripheral Interface and Protocol Conversion, Test Fixture Control, Product Routing and Configuration Logic, Embedded Control Glue Logic.
Industrial Control Signal Decoding
The ATF22V10C-7PC fits compact industrial control boards that must decode switches, interlocks, selectors, or machine-state signals into internal logic commands. Its 10 macrocells provide substantially more capacity than a basic PAL while retaining a simple 24-pin PDIP footprint for repairable industrial equipment. The 7 ns speed class supports general control logic rather than high-speed datapath processing. Because the configuration is stored in electrically erasable Flash memory, the controller retains its programmed behavior across power cycles without an external configuration loader. Engineers should verify industrial temperature requirements, input thresholds, output drive, and supply tolerance against the Microchip datasheet before production release.
推荐
Legacy GAL22V10 Migration
The ATF22V10C-7PC is suited to maintaining or modernizing equipment built around the GAL22V10. Microchip specifically identifies the ATF22V10C family as pin-to-pin and JEDEC fuse-map compatible with the GAL22V10, providing a direct basis for board-level replacement. The 7 ns variant also preserves the original device's 5 V operating class while adding electrically erasable Flash configuration. Migration still requires careful review of AC timing, DC output characteristics, supply limits, and temperature coverage because Microchip notes that the electrical characteristics are similar rather than identical. Existing PCB artwork and GAL22V10 logic documentation can therefore provide a strong starting point for a controlled substitution.
推荐
Peripheral Interface and Protocol Conversion
The ATF22V10C-7PC can implement small protocol converters, address decoders, command qualifiers, and interface glue where discrete logic would be unnecessarily large. With 10 macrocells, 500 equivalent gates, and a 7 ns speed rating, the device provides a practical balance between functional density and simple reprogrammability. Flash-backed configuration allows different interface personalities to be loaded during production or maintenance without replacing the IC. The 24-pin PDIP package also makes the part suitable for legacy motherboard and controller layouts. Board designers should account for the device's 5 V supply requirement and verify every signal against the datasheet's pinout and AC timing tables before connecting external buses.
推荐
Test Fixture Control
The ATF22V10C-7PC is appropriate for test fixtures, programmable test adapters, and automated tester control boards that combine multiple digital stimuli and response checks. Its 10 macrocells can consolidate Boolean control functions that would otherwise require separate gate packages, while the 7 ns timing class provides useful margin for ordinary fixture control paths. Electrically erasable Flash programming permits fixture personalities to be changed without a new PCB. The 24-pin PDIP package simplifies socketed prototyping and replacement. Engineers must verify actual fixture timing at the system level, including propagation delay, setup and hold requirements, output loading, and any long interconnect or cable effects not covered by the device's internal timing specifications.
推荐
Product Routing and Configuration Logic
The ATF22V10C-7PC can serve as a nonvolatile routing controller in equipment with selectable operating modes. Its 10 macrocells are sufficient for Boolean combinations of mode inputs, interlocks, status flags, and output enables, while 7 ns performance suits ordinary control paths. The Flash configuration remains present when power is removed, which supports deterministic startup behavior in appliances, test systems, and legacy automation equipment. A 24-pin PDIP package also allows the part to be used in through-hole serviceable boards rather than forcing a surface-mount redesign. Before implementation, confirm that each required routing function fits the macrocell structure and that the selected JEDEC fuse map remains supported for the intended configuration.
推荐
Embedded Control Glue Logic
The ATF22V10C-7PC is useful as glue logic between a microprocessor, memory, I/O expander, and discrete actuators in a small control system. Rather than dedicating general-purpose microcontroller pins to simple Boolean functions, the PLD can implement decoding, qualification, latching, and mutually exclusive control functions. Its 7 ns speed supports conventional control-loop timing, and the nonvolatile Flash configuration provides a stable implementation without repeated configuration after reset. The 24-pin PDIP package is particularly valuable for repairable industrial boards and prototypes. Designers should reserve resources for input conditioning and output isolation where required, and confirm that the 5 V device is compatible with the board's signal levels and supply tolerance.

设计说明
Do not treat every GAL22V10 ordering code as an automatic substitute for the ATF22V10C-7PC. Microchip confirms pin-to-pin and JEDEC fuse-map compatibility for the ATF22V10C family, but its support notice also warns that AC and DC characteristics may differ in minor ways. Compare the original device and replacement datasheets for supply tolerance, output current, input thresholds, AC timing, and temperature before approving a substitution.
The ATF22V10C family operates from a nominal 5 V rail, with the C suffix documented at 5 V ±5% and the CQ suffix at 5 V ±10%. Use the exact suffix when interpreting the allowable supply range. Decoupling and rail design should follow the manufacturer datasheet, and supply noise should be checked against the device's timing and input-threshold requirements rather than inferred solely from the nominal 5 V value.
The target is a 24-pin through-hole PDIP device. Preserve the original GAL22V10-compatible footprint and verify component orientation against the official package drawing before soldering. Although the family is described as pin-to-pin compatible, engineers should still check socket or PCB pin numbering, pin-1 orientation, and any application-specific signal assignments instead of relying on an informal board sketch.
Although the ATF22V10C-7PC is a 7 ns PLD, board-level signal integrity can still determine functional margin. Keep clock-like and fast edge-sensitive routes short, minimize stub branches, maintain a continuous ground reference, and place any required bypass capacitors close to the supply pins. Validate final timing at the actual load capacitance and trace length because device timing specifications alone do not include PCB propagation delay.
合规信息
The supplied verified excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the ATF22V10C-7PC is a commercial programmable logic device rather than an automotive-qualified ordering variant.
