APA150-FG256 - 150K Gate Flash FPGA | Microchip Technology
部品番号: APA150-FG256 ✓ 生産中APA150-FG256 概要
An FPGA is a programmable semiconductor whose internal logic blocks, routing, and I/O can be configured after manufacture. In the device hierarchy, the APA150 belongs to the ProASICPLUS family of flash-based FPGAs, a category between fixed-function logic devices and mask-programmed custom ASICs. Flash configuration memory retains the programmed logic image without continuous external support, while programmable I/O and internal RAM allow a single device to implement multiple control functions.
The APA150-FG256 combines 150,000 logic gates with 186 user I/O in a single 256-ball package. Its 36,864 RAM bits support on-chip data storage, buffering, and state-machine implementations. The 180 MHz operating capability gives designers substantially more timing headroom than legacy low-density PLD solutions. A 2.3 V to 2.7 V core supply range also simplifies power planning in systems that already operate around 2.5 V.
ProASICPLUS devices use flash technology rather than SRAM-only configuration, so the programmed image remains available after power is removed. This characteristic is valuable for control equipment, test systems, and industrial modules where deterministic startup behavior is required. The FG256 ordering code identifies the 256-ball package configuration, while the APA150 prefix identifies the specific ProASICPLUS density and family.
Typical implementations include industrial controllers, instrument signal conditioning, communication interfaces, embedded protocol bridges, and general-purpose logic consolidation. The 186 available I/O allow the device to connect directly to multiple digital peripherals without external glue logic. Designers can also time-share the 36,864 RAM bits for packet buffering, FIFO structures, and small local data stores when the application requires more than pure combinational or registered logic.
When laying out a board, follow the Microchip package footprint, ball assignment, and recommended land pattern exactly. Confirm the I/O voltage, configuration interface, decoupling requirements, and unused-ball treatment in the ProASICPLUS Flash Family FPGAs datasheet before fabrication. Because device programming and pin multiplexing are design-specific, validate the final bitstream on the intended PCB rather than relying only on simulation.
This page organizes the verified device characteristics, package identity, sourcing options, and engineering guidance for designers evaluating the APA150-FG256. It also distinguishes true pin-compatible family options from unrelated parts that merely use similar APA references, helping PCB, procurement, and firmware teams evaluate a migration on a common technical basis.

主な用途
APA150-FG256 の用途: 6 件s: Industrial Control Logic Consolidation, Data Acquisition and Signal Conditioning, Protocol Bridge and Communication Interface, Programmable Test and Measurement Front End, Embedded Data Storage and FIFO Buffering, Embedded System Peripheral Consolidation.
Industrial Control Logic Consolidation
The APA150-FG256 is suitable for consolidating several discrete control blocks into one programmable device. Its 150,000 system gates and 186 user I/O can connect sensors, discrete I/O, counters, interlocks, and machine-control outputs without separate CPLDs or glue logic. The 180 MHz clock capability provides timing margin for synchronized sampling and state-machine updates. Because the configuration is stored in nonvolatile flash, the controller can resume its defined operating state after a power interruption without a separate configuration loader.
おすすめ
Data Acquisition and Signal Conditioning
The APA150 can serve as a high-speed digital front end when a design requires parallel capture, digital filtering, or interface isolation between sensors and a host processor. The 186 user I/O accommodate multiple converter channels and control signals, while 36,864 RAM bits can buffer sampled words before transfer. Its 180 MHz capability supports pipelined acquisition logic. Designers should use the device pin-description tables to confirm I/O voltage standards and timing constraints for the selected external converters.
おすすめ
Protocol Bridge and Communication Interface
The APA150-FG256 is well suited to protocol conversion when legacy parallel peripherals must be connected to a serial processor or communication system. Its 186 I/O provide parallel-side connections, and 36,864 RAM bits support packet staging, FIFOs, and protocol state. At up to 180 MHz, the device can run deterministic clock-domain crossing and framing logic. Because third-party distributors list the exact APA150-FG256 order code with 36864 RAM bits and 186 I/O, engineers can size these buffers directly against the published resources.
おすすめ
Programmable Test and Measurement Front End
The APA150-FG256 can implement sequencing, fixture control, timing generation, and result capture around an instrument or tester. Its 150,000 gates provide capacity for parallel stimulus generation and response checking, while 186 user I/O reduce the need for external logic. The flash-based configuration supports repeatable field updates when test parameters change. Timing closure remains the main constraint, so engineers should use the 180 MHz device rating only after confirming the selected pin, package, and configuration conditions in the family datasheet.
おすすめ
Embedded Data Storage and FIFO Buffering
The 36,864 RAM bits in the APA150-FG256 allow designers to add local buffering without adding external memory when data volumes remain modest. Typical uses include command queues, status histories, sample windows, and temporary packet storage between acquisition and processing stages. The device's 150,000 logic gates leave capacity for the associated addressing, arbitration, and integrity logic. Use the family datasheet to allocate RAM blocks correctly and avoid timing conflicts between RAM access and high-speed I/O.
おすすめ
Embedded System Peripheral Consolidation
The APA150-FG256 can consolidate glue logic around an MCU, DSP, or memory interface in compact embedded systems. Its 186 user I/O provide dedicated address decoding, interrupt control, bus arbitration, and peripheral-select functions, reducing board area compared with multiple discrete logic devices. The 180 MHz capability supports faster interface marshalling than many legacy CPLDs. For systems where software can meet the timing requirements, an MCU from the Microchip portfolio may be simpler; use the FPGA when deterministic hardware parallelism is the deciding requirement.

設計ノート
Use the FG256 256-ball land pattern and Microchip ball-assignment table directly for placement and routing. A 256-FPBGA requires careful escape routing between the 0.5 mm-class ball field and the surrounding components, so confirm the actual ball pitch and courtyard from the package drawing. Reserve the configuration, clock, and dedicated supply balls according to the family datasheet rather than treating all non-user balls as interchangeable routing resources.
Plan the core rail around the published 2.3 V to 2.7 V operating range and follow the family datasheet for supply sequencing and decoupling. Place the recommended local bypass capacitors at the associated power and ground balls, with short return paths that avoid plane splits beneath the device. Verify the I/O voltage domains separately because the core supply specification alone does not define every user-I/O voltage level.
Do not migrate among the APA150 ordering codes solely from the suffix. Check package type, ball map, temperature grade, speed grade, configuration method, and device family revision before substituting. The APA150-FG256I option changes the environmental grade, while X79 and FGG options change ordering details that can carry different timing or package definitions. Confirm the exact part in the Microchip ordering guide and complete a static timing review.
Treat clock inputs, configuration signals, and high-speed user I/O as separate routing classes. Keep clock traces short, provide a continuous reference plane, and avoid routing over split power or ground planes. For 180 MHz-class operation, check board skew, load capacitance, and pin drive settings against the datasheet timing tables. Flash configuration helps preserve the bitstream, but it does not remove the need for clean external clocking and I/O conditioning.
コンプライアンス情報
