APA075-TQ100 - 75K-Gate, 180MHz Flash FPGA | Microchip

Industrial Control and Automation

The APA075-TQ100 fits industrial control logic that requires parallel I/O, flexible interconnect, and retained configuration. Its 66 user I/O can support digital inputs, actuator commands, interlocks, counters, and communication interfaces, while the 75,000 gates and 3,072 logic cells provide capacity for control state machines and datapath logic. The nonvolatile flash configuration allows the controller to recover its programmed function immediately after power restoration, which is useful in unattended machinery. The 180 MHz maximum stated frequency also permits registered control pipelines when timing closure is straightforward. Before releasing a new industrial design, verify the operating-temperature grade, supply voltages, and device lifecycle because those requirements determine whether this legacy ProASICPLUS part is appropriate.

Data Acquisition and Signal Conditioning

The APA075-TQ100 is appropriate for data-acquisition front ends that require deterministic parallel sampling, digital filtering, and interface adaptation. Its 66 user I/O can connect multiple converters, parallel buses, trigger signals, and status lines, while 3,072 logic cells can implement counters, timing units, filters, and control sequences. Registering signals in the programmable fabric can provide predictable sampling behavior, and the 180 MHz maximum frequency offers a practical ceiling for many control and data-formatting paths. Because the device is programmed through nonvolatile flash, field-updated acquisition configurations remain available without a separate configuration memory. Engineers should use the manufacturer timing and pin tables to define input registers, clock domains, and supported electrical interfaces for each converter.

Communications Protocol Interface

APA075-TQ100 can serve as a dedicated communication interface or protocol translator between legacy parallel logic and newer serial systems. The 75,000-gate device provides enough programmable resources for framing, checksums, byte assembly, buffering, and clock-domain adaptation, while 66 I/O can expose parallel data, interrupts, and control signals. Its nonvolatile configuration is valuable in equipment that must resume communication functions without an external loader. The 180 MHz maximum frequency can support moderately fast internal datapaths, although actual line rates depend on the selected I/O standards, clocking, timing constraints, and board-level transceiver behavior. Use the manufacturer pin-description and timing documentation to partition the design into clocked logic and properly constrained interfaces.

Test and Measurement Equipment

The APA075-TQ100 is suitable for programmable test equipment that coordinates stimulus, response capture, sequencing, and front-panel control. Its 66 I/O can connect test fixtures, status indicators, triggers, counters, and parallel measurement peripherals, while its programmable fabric can implement flexible timing sequences and result formatting. Nonvolatile flash allows a bench instrument to retain distinct test configurations between power cycles, and live-at-power-up behavior can reduce startup complexity. The 3,072 logic cells and 180 MHz maximum stated frequency support registered control pipelines, although analog measurement accuracy is determined by external converters rather than the FPGA. Validate device speed, temperature, and lifecycle requirements before using this legacy family in new production instrumentation.

Embedded System Peripheral Consolidation

APA075-TQ100 can consolidate several fixed digital functions around an embedded processor or microcontroller. A typical implementation assigns parallel buses, timers, interrupt logic, display controls, and custom peripheral interfaces to the programmable fabric, reducing the number of separate glue devices. The 66 user I/O provide substantial connectivity for 8-bit and 16-bit datapaths, while 3,072 logic cells can host control state machines and data-format converters. Because the configuration is nonvolatile, the logic remains available without a continuous loader and can simplify deterministic startup. The 180 MHz maximum stated frequency supports registered transfers, but system timing, arbitration, and clock-domain crossings must be constrained carefully. Check the manufacturer clock requirements and supported I/O standards before defining board-level interfaces.

Fixed-Function ASIC Replacement

The APA075-TQ100 is useful when a traditional masked ASIC is too inflexible for evolving logic, masks, or product variants. Its 75,000 gates and 3,072 programmable logic cells provide a practical implementation scale for fixed datapath blocks, control logic, and interface glue that can be revised through programming rather than silicon respins. The 66 I/O support external memories, converters, and control signals, while nonvolatile flash provides a stable configuration at power-up. The 180 MHz maximum frequency can satisfy many synchronous control and data-processing designs when timing constraints and I/O timing are properly closed. Because APA075-TQ100 is a legacy family member, compare its lifecycle, environmental qualification, and procurement position against current programmable-logic options before committing a new design.
