ATF22V10B-15SC - 15 ns 10-Macrocell EE PLD | Microchip
部品番号: ATF22V10B-15SC ✗ 生産終了ATF22V10B-15SC 概要
An electrically erasable programmable logic device, or EE PLD, is a programmable-logic semiconductor whose configuration is stored in nonvolatile electrically erasable memory. Within the broader hierarchy, an EE PLD is a form of PLD, which belongs to the broader logic-IC and semiconductor families. Unlike a one-time-programmable fuse-based device, electrically erasable technology allows the logic configuration to be erased and reprogrammed during development, production, or field maintenance. This makes the ATF22V10B useful where engineering changes or reusable configurable logic are valuable.
The ATF22V10B family supports speed grades down to 7.5 ns, while the ATF22V10B-15SC provides a 15 ns grade. The manufacturer identifies the underlying ATF22V10B as a high-performance electrically erasable CMOS PLD using proven electrically erasable flash-memory technology. The commercial speed range is specified at 5 V ±5%, while military and industrial ranges use the wider 5 V ±10% operating-voltage range. The listed low-power operating point can be as low as 10 mA.
With 10 macrocells, the ATF22V10B-15SC implements Boolean logic, state-machine behavior, address decoding, interface conditioning, and control functions without requiring a separate microcontroller. The 15 ns grade favors designs in which deterministic combinational and registered logic is more important than very high I/O throughput. Its nonvolatile configuration also permits field updates without supplying power during storage.
Typical uses include industrial control and instrumentation, legacy equipment upgrades, peripheral-interface decoding, programmable switch logic, test fixtures, and small embedded control systems. The ATF22V10B-15SC is particularly suitable when a compact SOIC footprint, electrical reconfiguration, and straightforward fixed-logic implementation are more useful than the software flexibility of a microcontroller or FPGA.
Designers should use the manufacturer datasheet pin-description table when assigning PCB signals and confirm operating-voltage, timing, output-drive, and temperature limits against the selected grade. Input and output paths also require normal CMOS decoupling and signal-integrity practices, especially when external signals drive the configurable I/O paths.
This page combines the manufacturer device information, lifecycle and package findings, drop-in alternatives, application guidance, and engineering-focused comparisons. It adds practical selection context and design notes while keeping the device-specific facts tied to the manufacturer datasheet and product information.

主な用途
ATF22V10B-15SC の用途: 6 件s: Industrial Control Logic, Legacy Equipment Upgrade, Address and Command Decoding, Programmable Switch and Signal Conditioning, Test and Measurement Fixtures, Peripheral Interface Conditioning.
Industrial Control Logic
The ATF22V10B-15SC is suitable for compact industrial control blocks that require fixed decoding, sequencing, or state-machine behavior at a nominal 5 V supply. Its 10 macrocells provide a practical logic budget for combining input conditions into control outputs without introducing a microcontroller. The electrically erasable flash configuration allows design revisions and production-programming changes. Timing must be checked against the 15 ns speed grade, and the commercial-temperature ordering code should be replaced by an industrial-rated option when the ambient range exceeds its specification.
おすすめ
Legacy Equipment Upgrade
For obsolete or discontinued control boards, the ATF22V10B-15SC can implement replacement glue logic while retaining nonvolatile configuration in electrically erasable flash memory. Ten macrocells are useful for address decoding, command qualification, alarm latching, and related interface functions. The 24-SOIC format permits direct integration where the footprint already exists, although pin assignments and logic macrocell usage must match the original device. Confirm availability, condition, and traceability before using this option for production maintenance.
おすすめ
Address and Command Decoding
The ATF22V10B-15SC can decode addresses or qualify commands into control outputs using its 10 configurable macrocells. A 5 V supply and 15 ns speed grade fit many asynchronous control paths where predictable propagation timing matters more than programmable processor software. The nonvolatile configuration prevents logic from changing after power removal. Validate setup and hold timing, output behavior, and unused-pin requirements against the manufacturer datasheet before finalizing the decoder equations.
おすすめ
Programmable Switch and Signal Conditioning
The ATF22V10B-15SC can combine enable, limit, interlock, and polarity conditions into programmable switching controls. Its electrically erasable architecture allows the logic map to be changed during equipment qualification without replacing fuse-based devices. The 24-SOIC package is appropriate for compact surface-mounted control boards. Because the 15 ns grade is the slowest considered in this comparison, timing margin should be calculated from the longest required input-to-output path, and unused inputs should be handled according to the datasheet.
おすすめ
Test and Measurement Fixtures
The ATF22V10B-15SC is useful in test fixtures for selecting measurement paths, generating control strobes, combining limits, and implementing short fixture-specific logic sequences. Its 10 macrocells can replace multiple conventional gate packages when the design is carefully mapped, while the 24-SOIC package simplifies surface-mount assembly. The device must remain within its 5 V commercial operating range and electrical limits. Fixture timing should be verified with the actual loading, output loading, and cable arrangement rather than relying only on the nominal 15 ns grade.
おすすめ
Peripheral Interface Conditioning
The ATF22V10B-15SC can place configurable adaptation logic between slower legacy peripherals and a system bus. Typical tasks include signal qualification, command formatting, handshake generation, and isolating incompatible transition sequences. Electrically erasable configuration makes it useful for systems whose peripheral interfaces vary across product variants. The 10-macrocell limit constrains large interface functions, so partitioning may be necessary. Verify every timing path against the 15 ns grade and include the device's supply and output characteristics in interface-level simulations.

設計ノート
Do not treat a 24-SOIC and a 24-pin DIP as interchangeable. The ATF22V10B family has multiple package and ordering options, but the -15SC designation corresponds to the 24-SOIC surface-mount configuration. Confirm that the replacement uses the same footprint, pin sequence, power pins, configuration pins, and I/O assignments. Also verify the speed and temperature suffix against the original design before release.
Calculate timing from the longest configured macrocell path rather than from the 15 ns family speed grade alone. Include input setup time, registered clock requirements, output delay, and the selected 5 V operating tolerance. A 10 ns ATF22V10B option provides additional timing margin, but it does not remove the need to constrain clock distribution, avoid long unprotected traces, and maintain valid levels at every configurable I/O pin.
Use the manufacturer 24-SOIC pin-description table to assign power and ground before placing decoupling capacitors. Place the power bypass capacitor close to the device supply pins and follow the datasheet layout guidance for programming and configuration signals. Preserve the package outline and pin-1 orientation in the footprint library, especially for replacements sourced from different production lots or legacy documentation.
