APA075-TQ144 - 75,000-Gate Flash FPGA | Microchip Tech
N.º de pieza: APA075-TQ144 ✗ Fin de vidaAPA075-TQ144 Descripción general
A field-programmable gate array, or FPGA, is a reconfigurable semiconductor used to implement digital logic through user-programmed interconnect and logic blocks. An FPGA belongs to the programmable-logic hierarchy, sitting above fixed-function logic ICs and below programmable-system designs. Compared with a mask-programmed ASIC, an FPGA permits design revisions after manufacture; compared with a microcontroller, it can execute multiple logic functions concurrently using dedicated hardware resources.
The APA075 family combines flash-based, nonvolatile configuration with up to 75,000 gates and 107 available I/O in the selected package. Its 27,648 RAM bits provide on-chip storage for data, state, and implementation-dependent logic. The 0.5 mm package pitch supports a 144-pin TQFP footprint measuring 20 x 20 mm, while the 180 MHz maximum frequency provides a practical target for clocked datapaths, control logic, and interface bridging.
The ProASICPLUS architecture is intended for low-to-medium-density programmable logic. Flash programming makes the configuration nonvolatile, avoiding an external loader in systems that do not require runtime reconfiguration. A design still needs suitable input and output constraints, clocking, power distribution, and a compatible programming implementation before timing closure. Device speed, temperature grade, and ordering suffix must be checked against the production requirements of the assembled system.
Typical uses include industrial control logic, instrumentation, communications interface consolidation, embedded protocol bridges, and general-purpose logic replacement. The 107 I/O count is especially useful when a design must retain numerous discrete digital connections while replacing several programmable-logic packages. Its 27,648 RAM bits can also support packet buffers, counters, lookup tables, and state machines without relying on external memory for moderate workloads.
The principal design consideration is complete package-specific verification. Confirm the pinout, configuration interface, supported clock sources, I/O standards, and programming hardware against the Microchip product documentation before committing a 144-lead PCB. Avoid treating a similarly named APA075 ordering code as interchangeable without confirming speed grade, temperature range, compliance status, and exact lead assignments.
This product view combines the principal APA075-TQ144 specifications, same-package replacement options, application guidance, and an eight-parameter engineering comparison. It is designed to help designers assess logic capacity, I/O availability, package constraints, and replacement risk before integrating the device into a larger embedded control system.

Aplicaciones típicas
APA075-TQ144 es adecuado para 6 aplicacións: Industrial Control Logic, Instrumentation Signal Conditioning, Communications Interface Consolidation, Embedded Protocol Bridge, Data Acquisition Conditioning, Programmable Logic Consolidation.
Industrial Control Logic
The APA075-TQ144 fits industrial control systems that need parallel digital I/O, state-machine logic, counters, and communication isolation without relying on a microcontroller for every timing-critical function. Its 107 I/O provide ample board-level connectivity, while 3,072 cells and 27,648 RAM bits can implement sequencing, interlock logic, and small data buffers. The 180 MHz stated maximum supports demanding clocked control blocks, although actual timing depends on the selected device grade and design constraints. Before layout, verify the exact pin assignments, supported I/O standards, supply requirements, and temperature limits in the manufacturer documentation.
Recomendado
Instrumentation Signal Conditioning
APA075-TQ144 is appropriate for instrumentation front ends that require digital filtering, calibration tables, trigger logic, and control sequencing around analog converters. The 27,648 RAM bits can support sample buffers, counters, calibration coefficients, and intermediate data, while 107 I/O leave ample connections for converter data, status signals, and instrument control. At the stated 180 MHz maximum frequency, the FPGA can process parallel datapaths efficiently. The design should include constraints for each clock domain and must verify that the chosen package variant supports the required I/O voltage and operating temperature.
Recomendado
Communications Interface Consolidation
The APA075-TQ144 can consolidate several slower serial or parallel communication interfaces into a compact programmable-logic block. Its 75,000 gates and 3,072 cells suit protocol converters, framing logic, FIFOs, CRC processing, and bus arbitration, while 27,648 RAM bits provide storage for packet buffers and counters. The 107 I/O allow direct attachment to multiple buses and status lines without an external ASIC. Clock-domain crossing and timing must be handled carefully, and engineers should confirm configuration, I/O, and performance details for the exact APA075 ordering code before schematic release.
Recomendado
Embedded Protocol Bridge
APA075-TQ144 suits embedded bridges that translate between dissimilar bus widths or interface timing requirements using parallel logic and block RAM. Available resources can support transmit and receive state machines, byte alignment, command parsing, flow control, and error recovery without occupying a separate processor. The device's stated 180 MHz ceiling allows the fabric to run faster than many low-speed industrial protocols, while 27,648 RAM bits support moderate queueing. The implementation should use conservative timing constraints and test bus idle, timeout, reset, and contention behavior across every operational state.
Recomendado
Data Acquisition Conditioning
APA075-TQ144 can implement the digital conditioning stage of a data-acquisition system by combining parallel ADC interfaces, timing generation, sample counters, trigger logic, and local buffering. The 107 I/O accommodate converter data buses and control signals, and the 27,648 RAM bits can hold multiple samples or intermediate products. Its programmable architecture allows acquisition sequencing and trigger thresholds to be changed without respooling a fixed ASIC. Engineers should budget timing margin for converters and clocks, verify input thresholds, and ensure that fan-out and trace routing do not compromise signal integrity.
Recomendado
Programmable Logic Consolidation
APA075-TQ144 is useful when replacing several small fixed-function logic packages with one configurable device. The 75,000 gates and 3,072 cells can consolidate decoding, arbitration, timing, status registers, and interface glue logic, while the 107 I/O reduce board-level package count. Nonvolatile flash configuration allows the consolidated design to retain its configuration after power is removed. Consolidation still requires a resource and I/O audit, careful power planning, and timing verification. If the target board uses APA075-TQ144 symbols, each replacement candidate must receive a separate pin-by-pin and electrical review.

Notas de diseño
Base the PCB footprint on the 144-lead TQFP package drawing rather than treating the APA075 family name as sufficient package confirmation. The package is 20 x 20 mm with a 0.5 mm pitch, so courtyard clearance, paste volume, solder-mask definition, and the pin-1 orientation must follow the manufacturer drawing. Verify every power and ground connection in the pin-description table. A symbol-library error on a 0.5 mm TQFP can place several I/O nets on the wrong package pads even when the body dimensions appear correct.
Use the exact supply-voltage limits and I/O voltage requirements from the documentation for the selected ordering grade before adding decoupling. Place the required input, output, and bypass capacitors close to their associated power and ground pins, with a low-impedance return path to the ground plane. Account for simultaneous I/O switching because it can increase dynamic current and ground bounce. Where the design uses several I/O banks or external memories, isolate noisy switching paths from precision or reference circuitry to prevent false triggering and timing failures.
Do not approve a replacement solely because it has 144 leads. For APA075-TQG144, APA075-TQG144I, APA075-TQ144I, APA075-FTQ144, or APA075-FTQG144, compare the complete pin description, speed grade, temperature range, supply limits, I/O standards, configuration method, and compliance status. The TQG-related listings distinguish lead-free construction from the target's contains-lead status. Xilinx package-class alternatives also require conversion of the configuration architecture and timing constraints, so they need schematic review, synthesis, place-and-route, timing closure, and hardware testing.
Constrain every clock input with the correct period and uncertainty, and define generated clocks only through the supported clocking methodology. The stated 180 MHz value is a device rating rather than a guaranteed system operating frequency. Use synchronous reset and state-machine recovery practices, avoid routing long combinational paths between registers, and reserve margin for local-clock skew. For external converters or memory interfaces, constrain input and output delays based on board-level timing, and treat package and board skew as part of the interface budget.
