ATF22V10B-15JC - 10-Macrocell 15ns EE PLD | Microchip Technology
부품 번호: ATF22V10B-15JC ✗ 단종ATF22V10B-15JC 개요
An electrically erasable PLD is a programmable logic device that stores its configuration in nonvolatile EEPROM or Flash memory and can be reprogrammed in the field. The ATF22V10B belongs to the simple PLD hierarchy, where configurable macrocells implement sum-of-products logic functions. Compared with a fixed gate array or a fully programmable FPGA, this device provides a compact, lower-complexity solution for glue logic, control decoding, state-machine sequencing, and interface conditioning.
The ATF22V10B-15JC provides a 15 ns propagation-delay grade, 10 macrocells, 20 input pins, and 10 output pins. Its electrically erasable Flash memory technology supports reprogramming, while the device is manufactured using a high-reliability CMOS process. The family is designed for commercial, industrial, and military temperature options, with speed grades specified over a 5 V plus-or-minus 10 percent supply range for military and industrial grades and 5 V plus-or-minus 5 percent for other applicable grades.
The 28-pin PLCC package offers a practical surface-mount alternative to older through-hole PLD packages. Its configuration memory retains programmed logic across power cycles, allowing the device to serve as a standalone logic controller. The registered inputs and outputs provide predictable timing for control logic, and the device's macrocell architecture makes it suitable for designs that require more flexibility than a PAL but less routing and configuration complexity than an FPGA.
Typical uses include industrial automation controllers, legacy equipment interfaces, programmable relay logic, instrument control panels, embedded sequencing, and board-level adaptation between fixed digital functions. In these applications, the ATF22V10B-15JC can consolidate multiple gates, counters, decoders, and state-transition logic into one configurable device while reducing the number of separate logic ICs required.
When designing around this PLD, verify the power-supply tolerance, output-drive requirements, and timing budget against the system clock. Program the device with the appropriate Atmel or Microchip programming tool, and use the manufacturer pin description and programming guidance when assigning board functions. This page combines device specifications, package details, drop-in alternatives, application guidance, and practical design considerations for engineers maintaining or redesigning legacy programmable-logic boards.

일반적인 애플리케이션
ATF22V10B-15JC 적합 용도: 6 애플리케이션s: Industrial Automation Control Logic, Legacy Equipment Interfaces, Programmable State Sequencing, Relay and Discrete Control Interface, Instrumentation Signal Conditioning, Embedded Board-Level Adaptation.
Industrial Automation Control Logic
The ATF22V10B-15JC fits compact industrial control boards that require programmable decoding, sequencing, and interlock logic close to a controller. Its 10 macrocells and 20 inputs can combine sensor-condition signals and machine commands into compact Boolean functions, while the 10 outputs can drive control or interface stages. The 15 ns grade supports control paths that are not dominated by very high-speed communications. The 5 V supply requirement should be checked against the industrial power tree, and the exact temperature grade must match the enclosure environment. Use the device for fixed control logic rather than high-bandwidth data processing, and validate timing against the controller handshake and fault-response requirements.
추천
Legacy Equipment Interfaces
ATF22V10B-15JC can provide the missing programmable glue logic found in legacy instruments, industrial machines, and older controller boards. A configurable PLD can translate between unusual signal formats, generate enables, qualify interlocks, and combine discrete gate logic without requiring a redesign of the surrounding analog and power sections. Its nonvolatile Flash configuration supports field reprogramming and simplifies board revisions. Because the target package is a 28-pin PLCC, the legacy footprint and programming workflow should be checked carefully before substitution. Validate signal levels, clock assumptions, and output timing against the original schematic and the manufacturer datasheet.
추천
Programmable State Sequencing
The ATF22V10B-15JC is suitable for state-machine and sequencing functions where a compact set of registered outputs must follow a defined sequence of input conditions. Its macrocell architecture supports multiple sum-of-products functions and sequential behavior in one configurable device, reducing the number of separate counter and decoder packages on a board. The 15 ns propagation-delay class should be compared with the shortest required clock-to-output or input-to-output interval in the timing diagram. The device is most effective when the sequence is modest and the board does not need FPGA-style routing flexibility. Keep programming and reset behavior in mind when designing startup and recovery states.
추천
Relay and Discrete Control Interface
ATF22V10B-15JC can implement relay-control decode, interlocks, pulse qualification, and discrete output sequencing in equipment-control electronics. The 20-input capability allows the PLD to combine multiple switch, sensor, and interlock conditions before generating one of ten controlled outputs. This approach is useful for maintaining older machinery where a small logic replacement is more practical than replacing the entire controller. Confirm that every output meets the voltage, current, and polarity requirements of the driven device, and account for any inductive-load flyback path outside the PLD. The 5 V logic supply and J-lead PLCC footprint should be checked during board inspection.
추천
Instrumentation Signal Conditioning
The ATF22V10B-15JC can implement digital signal conditioning, measurement-range decoding, and control gating around slower instrumentation systems. Its programmable Boolean logic allows designers to combine comparator outputs, operating-mode selections, and status flags into a compact control matrix. The device's 15 ns speed grade is appropriate for many control and sequencing paths, provided the instrumentation does not require high-speed signal processing. Keep sensitive analog and high-impedance nodes away from the PLD and follow the board's grounding and decoupling strategy. Validate input thresholds, output rise and fall behavior, and timing margins against the actual sensor and measurement-chain specifications.
추천
Embedded Board-Level Adaptation
ATF22V10B-15JC is useful for adapting one embedded subsystem to another by translating handshake signals, selecting among operating modes, or generating legacy-compatible timing. Its nonvolatile programmable logic permits a board to be updated without replacing fixed mask-programmed devices, while the 10 macrocell limit keeps the implementation appropriate for small adaptation tasks. The 28-pin PLCC package is especially relevant to maintenance of boards designed around the original ATF22V10B footprint. Before upgrading a board, confirm power sequencing, programming access, signal direction, and all unused-pin requirements in the manufacturer documentation. A programmed replacement should use an equivalent configuration file and equivalent logic state.

주요 차별점
- Maintains the original ATF22V10B logic resource configuration (vs ATF22V10B-10JC)
- Supports industrial-temperature substitution when the suffix is acceptable (vs ATF22V10B-15JI)
- Uses the same family-level Flash-programmable architecture (vs ATF22V10B-12JC)
설계 노트
The most important substitution check is the complete 28-pin PLCC footprint and pin description, not only the device family name. ATF22V10B variants can differ in speed grade and temperature suffix, so confirm the exact ordering code, supply tolerance, pin functions, and programming procedure in the manufacturer datasheet. Do not treat an industrial-temperature suffix as electrically and environmentally equivalent to the commercial-grade target without reviewing the original design requirements.
For board replacement, verify the PLCC footprint, lead pitch, pin-1 orientation, solderability, and access to the device programming interface. Keep the replacement orientation consistent with the manufacturer package drawing and inspect existing solder joints before applying heat. Because the device is configured in nonvolatile memory, preserve or reproduce the original configuration file and verify the programmed state after replacement.
The ATF22V10B-15JC uses a nominal 5 V supply, with the manufacturer specifying 5 V ±10% for military and industrial speed ranges and 5 V ±5% for other stated conditions. Check the supply at the PLCC pins under worst-case input, temperature, and output loading rather than relying only on the nominal board rail. Use local decoupling and ensure that power-up reset behavior and configuration states satisfy the surrounding control logic.
