APA075-FG144 - 75K Gate Flash FPGA, 180 MHz | Microchip Technology
MPN: APA075-FG144 ✓ פעילAPA075-FG144 סקירה
A field-programmable gate array, or FPGA, is a programmable-logic semiconductor whose interconnects and processing blocks can be configured after manufacture. Within the product hierarchy, an FPGA belongs to programmable logic, alongside CPLDs, while its physical construction uses CMOS logic fabric, flash memory, user I/O, and clocking resources. ProASICPLUS devices occupy the low-density programmable-logic segment and support reprogrammability combined with nonvolatile configuration retention.
The APA075 part family provides 75,000 system gates, 180 MHz internal operation, and 3,072 cells according to the device comparison data. Its flash-based configuration architecture removes the need for external configuration memory and permits the design to be reprogrammed in the field. The APA075-FG144 exposes 100 user I/Os and uses a 1 mm pitch FBGA-144 package intended for compact surface-mount designs.
The device is identified as a 144-pin CMOS FPGA in a 144-LBGA package. A second listing describes the same device as a 144-LBGA package with 100 I/Os, while the family documentation identifies the APA075 series as a ProASICPLUS Flash FPGA using a 0.22 µm CMOS process. These figures place the part in the low-density programmable-logic category rather than the high-performance FPGA class.
Typical uses include protocol bridging, glue-logic consolidation, embedded control logic, legacy system upgrades, and industrial or communications equipment where a compact nonvolatile FPGA is preferable to a mask-programmed ASIC. Because the configuration is stored in flash, the design also remains functional after power cycling without an external loader sequence.
The principal design consideration is that the FBGA-144 footprint requires a multilayer PCB, careful escape-routing, and thermal planning for the 0 to 70 C rated variant. Signal-integrity work should account for the 1 mm package pitch and clock distribution, while unused I/Os should be terminated according to the family guidance. Pin assignments and differential or clock-specific constraints must be taken from the package pinout tables before layout is released.
This page combines the verified device specifications with practical migration guidance, package-aware alternatives, application fit, and PCB-oriented design notes. It is intended to help engineers qualify the APA075-FG144 quickly while distinguishing package, grade, and temperature-suffix differences that can affect drop-in replacement decisions.

יישומים טיפוסיים
APA075-FG144 מתאים עבור 6 יישוםs: Protocol and Bus Interface Bridging, Industrial Equipment Control Logic, Data Acquisition and Instrumentation, Communications Line Interface Cards, Embedded System Function Consolidation, Legacy Platform Refresh.
Protocol and Bus Interface Bridging
APA075-FG144 is well suited to consolidating legacy parallel and serial interfaces into a compact programmable bridge. Its 75,000 system gates and 100 user I/Os provide enough fabric for state machines, protocol converters, and data-path arbitration without moving to a much larger FPGA. The 180 MHz internal frequency supports clocked interface logic, while on-chip flash retains the configuration after power cycling. Because the device is a 1 mm pitch 144-LBGA, the implementation should reserve multilayer escape routing and follow the family I/O standard constraints for each interface.
מומלץ
Industrial Equipment Control Logic
APA075-FG144 can implement deterministic control, sequencing, interlock, and alarm logic for industrial equipment with modest gate requirements. The 75,000-system-gate fabric is appropriate for consolidating several small programmable devices into one nonvolatile controller, and the documented 0 °C to 70 °C rating suits ordinary indoor equipment. On-chip flash allows field reprogramming without a separate configuration memory. The board design must still account for the FBGA-144 assembly requirements, industrial noise margins, grounded return paths, and isolation between field wiring and the FPGA core.
מומלץ
Data Acquisition and Instrumentation
APA075-FG144 is applicable to custom acquisition front ends where sensor multiplexing, timing control, and digital filtering must operate deterministically. Its 3,072-cell, 75,000-gate architecture provides moderate logic capacity, while 100 I/Os allow direct connection to converter and interface circuitry. The 180 MHz internal clock supports pipelined control and sampling logic, and flash configuration removes repetitive PROM loading at power-up. Engineers should budget careful clock routing, assign switched-capacitor and high-speed I/O constraints correctly, and confirm the supported voltage standards before assigning external converter outputs.
מומלץ
Communications Line Interface Cards
APA075-FG144 can serve as the programmable logic engine on a communications line card, combining framing, channelization, status, and backplane interface functions. The 100 user I/Os and 180 MHz internal operation accommodate moderate-rate parallel and serial processing stages, while nonvolatile flash supports network equipment that must retain its configuration through power interruptions. A production layout should provide continuous clock and power planes, keep sensitive outputs away from high-swing I/O, and follow the manufacturer ball-assignment guidance for supply and configuration pins.
מומלץ
Embedded System Function Consolidation
APA075-FG144 is useful when an embedded design needs programmable glue logic to consolidate discrete counters, decoders, timing blocks, and interface adaptation. Its nonvolatile flash configuration permits the design to operate immediately after power restoration, and its 75,000 gates provide meaningful capacity without the complexity of a high-end FPGA tool flow. Choose it when all logic fits within 3,072 cells and 100 I/Os, and when the legacy 144-LBGA package remains economical for the production volume. Verify toolchain support and existing board revision compatibility before standardizing the part.
מומלץ
Legacy Platform Refresh
APA075-FG144 supports refresh projects that retain a 144-LBGA board while moving logic from multiple mask-programmed or older PLD devices into one reprogrammable part. The 75,000-gate capacity and 100 I/Os align with medium-density consolidation, and flash programming shortens firmware-release workflows by allowing the logic image to be updated independently. Migration still requires equivalence checking of pin functions, I/O voltage standards, clock behavior, and initialization. The original board artwork is usable only when the alternative has an identical ball map and the intended grade is electrically compatible.

הערות תכנון
Treat the APA075-FG144 as a fine-pitch BGA escape-routing problem rather than a conventional component-placement task. The 1 mm pitch 144-LBGA footprint requires a multilayer board with short via structures from the inner signal layer to the device balls. Use the manufacturer mechanical drawing for pad and solder-mask definitions, and confirm the PCB fabricator's minimum drilled-via and laser-drilled microvia capabilities before committing the stack-up.
Follow the ProASICPLUS family reference circuit for core and I/O supply connections, including bypass capacitance and supply sequencing. Place the required decoupling capacitors close to their associated power balls and keep the return path continuous through the board plane. Since the exact operating voltage is established in the family datasheet rather than the part listing, do not design the rail arrangement until the device ordering code and power table have been reviewed.
Route clock signals first and isolate them from high-swing user outputs. The 180 MHz internal operating specification makes clock skew and return-path discontinuities relevant even when the external interfaces operate at lower rates. Assign clock-capable pins according to the family pin tables, avoid routing switching nodes beneath the FPGA, and keep configuration, programming, and JTAG access lines away from noisy analog or power-conversion sections of the board.
A suffix match alone does not establish drop-in compatibility for APA075 variants. Before substituting APA075-FGG144, APA075-FG144A, APA075-FG144I, APA075-FGG144I, or APA075-FGG144A, compare the complete ordering code, ball map, speed grade, and temperature grade in the family documentation. Also verify that the programming file and toolchain support the selected revision; otherwise a mechanically compatible part can still cause an unexpected build or qualification issue.
