ATF22V10C-7PX - 10-Macrocell 7 ns SPLD | Microchip
部品番号: ATF22V10C-7PX ✓ 生産中ATF22V10C-7PX 概要
An SPLD, or simple programmable logic device, is a user-programmable semiconductor that combines AND-array logic, OR-array logic, and programmable I/O resources into one reconfigurable logic component. Within the broader semiconductor hierarchy, the ATF22V10C-7PX belongs to the PLD family, which sits between fixed gate arrays and larger FPGAs. Its JEDEC-compatible 22V10 architecture is useful when a compact, deterministic logic block is required without implementing a full FPGA configuration system.
The ATF22V10C family provides 10 macrocells and approximately 500 gates in a 24-pin package. According to the Microchip ATF22V10C datasheet, electrically erasable Flash technology supports device reprogramming, while operating power dissipation can be as low as 10 uA typical. The -7 suffix identifies the 7 ns speed grade, making this version appropriate for control logic requiring short propagation delay while operating from a nominal 5 V supply.

The -7 suffix identifies the 7 ns speed grade, making this version appropriate for control logic requiring short propagation delay while operating from a nominal 5 V supply.
Typical uses include legacy interface decoding, industrial control sequencing, glue logic, counter and state-machine implementations, and compact system-support functions. The electrically erasable architecture also suits prototypes and field-updateable products where a conventional one-time-programmable fuse-based PLD would be less convenient. Designers should still verify the programmed fuse map and timing against the system clock budget.
For a new board, preserve the 24-pin PDIP footprint and assign every 22V10-compatible pin according to the pin-description table in the manufacturer datasheet. Check whether unused inputs require defined logic levels and whether the design needs a 5 V supply within the supported tolerance. The same package also allows speed-grade substitutions to be evaluated without changing the PCB footprint.
This page combines the manufacturer architecture description, distributor part identification, programming and pinout resources, drop-in family alternatives, and practical replacement considerations. It is intended to help engineers locate the datasheet, verify the package, compare speed grades, and determine whether the ATF22V10C-7PX remains appropriate for a legacy or redesign project.

主な用途
ATF22V10C-7PX の用途: 6 件s: Industrial Control and Sequencing Logic, Legacy Interface and Address Decoding, Counter and State-Machine Control, Instrumentation Signal Conditioning, Legacy GAL22V10D Migration, Programmable System Support and Glue Logic.
Industrial Control and Sequencing Logic
The ATF22V10C-7PX is well suited to compact industrial sequencing, command decoding, and interlock logic because its 10 macrocells can combine multiple Boolean functions without a full FPGA. The 7 ns speed grade provides deterministic propagation performance for control paths, while the nominal 5 V supply and documented 5 V ± 10% military and industrial range simplify legacy 5 V system integration. Electrically erasable Flash configuration also permits design revisions during commissioning. Validate the selected temperature grade against the enclosure environment and test every unused input for a defined state before production.
おすすめ
Legacy Interface and Address Decoding
The ATF22V10C-7PX can implement address decode, chip-select generation, and legacy peripheral interface glue in a small number of macrocells. Its 22V10-compatible architecture provides a practical migration path for GAL22V10D designs, and the electrically erasable Flash architecture allows logic changes without one-time fuse programming. A 7 ns speed grade can support moderate clock and propagation budgets, but the designer should calculate setup and hold requirements against the actual output path. The original GAL22V10D electrical characteristics and fuse map should still be reviewed before approving a replacement.
おすすめ
Counter and State-Machine Control
The ATF22V10C-7PX is appropriate for compact counters, command sequences, and finite-state machines that require deterministic logic and limited I/O. Ten macrocells provide enough capacity for small control functions, and the 7 ns grade supports short combinational paths relative to slower ATF22V10C options. Electrically erasable Flash makes it useful for prototypes where state definitions are likely to change. Check the product's registered-logic configuration, clock requirements, output enable behavior, and reset strategy against the state-machine timing budget before releasing the programmed device.
おすすめ
Instrumentation Signal Conditioning
The ATF22V10C-7PX can implement threshold selection, mode encoding, status decoding, and test-point control around analog measurement circuits. Its 24-pin PDIP package remains useful in instrument prototypes and legacy test equipment where board area is less restrictive than production miniaturization. The 10-macrocell architecture limits the part to compact Boolean tasks rather than complex DSP or high-speed data acquisition, while the 7 ns grade helps minimize delay in control paths. Follow the manufacturer's unused-pin guidance and verify that ground and supply pins connect directly to suitable planes.
おすすめ
Legacy GAL22V10D Migration
The ATF22V10C-7PX can support migration from GAL22V10D designs because Microchip identifies the ATF22V10C family as pin-to-pin and JEDEC-fusemap compatible. This makes it useful for restoring or redesigning boards built around the older PLD architecture. The migration is not automatic: AC and DC characteristics can contain minor differences, so supply tolerance, timing, programming, and unused-pin behavior must be compared. Load the revised fuse map, verify the programmed configuration, and perform boundary-condition tests before authorizing production substitution.
おすすめ
Programmable System Support and Glue Logic
The ATF22V10C-7PX is useful for adding programmable glue logic to a larger mixed-signal or processor-based system without introducing a large programmable-logic device. Functions can include bus decoding, power-state coordination, fault aggregation, and peripheral mode selection. The electrically erasable configuration allows controlled updates, while the 5 V operating point fits systems built around legacy TTL-compatible interfaces after voltage and signal-integrity checks. Avoid continuous high-frequency operation near timing limits, and confirm that startup outputs have safe states because the device may not control every signal during configuration or reset.

設計ノート
Treat the ATF22V10C-7PX as a through-hole 24-pin PDIP device when laying out the PCB. Place the socket or footprint to match the manufacturer's pin-1 orientation, preserve adequate clearance around adjacent pins, and connect the supply and ground pins with short, low-impedance paths. If a socket is used, verify its pin numbering and contact reliability; a mechanically similar socket with different row spacing is not a substitute for the specified 24-pin footprint.
Design the 5 V rail to remain within the applicable ATF22V10C supply range, including tolerance, ripple, and transient excursions at the device pins. The manufacturer describes 5 V ± 10% for military and industrial ranges and 5 V ± 5% for other ranges. Decouple close to the package with suitable supply and ground connections, and avoid relying on an upstream regulator's nominal value alone when testing supply sensitivity of the programmed logic.
Do not substitute the suffix without reviewing the complete ordering information. Speed grades such as 5 ns, 7 ns, and 10 ns can affect timing margin, while other suffix fields can identify commercial, industrial, or military temperature coverage. Confirm the exact temperature grade, supply range, package, and programming specification. Also follow the datasheet's direction for unused inputs and unused outputs so that no internal node floats during normal operation.
Review every path that crosses between the ATF22V10C-7PX and external circuitry using the data-sheet propagation-delay, setup, and hold parameters. The 7 ns grade is a speed designation and should not be treated as the complete system timing budget. Include external load capacitance, wiring, and peripheral timing, and test transitions at the expected supply range. For long PCB routes or noisy legacy systems, add suitable buffering rather than increasing the timing burden on the PLD output.
