APA750-PQ208 - 750K Gate Flash FPGA | Microchip | 208-Pin PQFP
料号： APA750-PQ208 ✓ 量产中APA750-PQ208 概述
A field-programmable gate array is a semiconductor device whose digital configuration is programmed after manufacture. Unlike a fixed-function application-specific integrated circuit, an FPGA can implement many logic architectures through a programmable interconnect and configurable logic cells. The APA750-PQ208 is positioned for designs requiring substantial parallel logic, moderate I/O density, dedicated SRAM, and the ability to update a board-level design without replacing the device.
Key features include 750,000 system gates, 158 programmable I/O pins, 147,456 bits of RAM, 350 MHz internal system performance, and 150 MHz external system performance. The device also supports 3.3 V, 32-bit PCI operation up to 50 MHz and offers a Schmitt-trigger option. Its 208-pin package and tray packaging support conventional surface-mount PCB assembly.
The ProASICPLUS architecture provides flash-based nonvolatile configuration, making the APA750-PQ208 useful for embedded control, communications, industrial automation, instrumentation, and test systems that need programmable logic with stored configuration. The family is positioned between simpler fixed logic and high-end FPGA/CPLD designs where logic density, SRAM availability, and I/O capability are more important than the very high performance or power levels associated with larger devices.
Typical applications include PCI peripheral logic, data acquisition, protocol bridging, industrial interface controllers, embedded storage controllers, and instrumentation signal-processing blocks. The 158 user I/Os support connections to external memories, transceivers, sensors, converters, and host buses, while the internal SRAM can support buffering, packet handling, state machines, and local data storage.
The principal design consideration is board-level resource planning. Engineers should confirm the exact pin assignments, supported I/O standards, voltage tolerances, configuration requirements, and clocking resources in the manufacturer datasheet before routing the PCB. The 2.3 V to 2.7 V core supply must be generated within the specified limits, and unused I/O behavior should be validated in the final system configuration.
This page combines the APA750-PQ208 technical profile, package information, application guidance, comparison parameters, and practical replacement considerations to support component selection and board-design review.

典型应用
APA750-PQ208 适用于 6 应用s: PCI Interface and Bus Bridging, Industrial Automation Controllers, Data Acquisition and Signal Processing, Communications Protocol Conversion, Instrumentation and Test Systems, Embedded Storage and DMA Controllers.
PCI Interface and Bus Bridging
The APA750-PQ208 fits PCI interface logic because it supports 3.3 V, 32-bit PCI operation up to 50 MHz while providing 158 programmable I/O pins for address, data, control, and peripheral connections. Its 147,456 bits of RAM can support local buffering, transaction staging, and state management, while the 750,000-system-gate density provides room for arbitration, command translation, and peripheral control logic. Designers should budget timing margin against the 50 MHz PCI requirement and verify all I/O standards against the manufacturer pin-description table.
Industrial Automation Controllers
The APA750-PQ208 is suitable for industrial automation blocks that coordinate sensors, actuators, counters, interlocks, and communication ports. The 158 programmable I/Os permit flexible connections to field-bus transceivers and digital industrial equipment, while 147,456 bits of RAM support packet buffering and machine-state storage. Its 2.3 V to 2.7 V operating range and 0 °C to 70 °C specification support controlled industrial environments when the complete system also satisfies its required environmental limits.
Data Acquisition and Signal Processing
The 750,000-system-gate APA750-PQ208 can implement parallel acquisition logic, digital filtering, trigger sequencing, channel control, and data formatting around external converters. Its 158 programmable I/O pins provide substantial connectivity for parallel converter data buses, while the internal RAM can hold sample blocks or intermediate results. The 150 MHz external system performance and 350 MHz internal system performance establish useful implementation targets, although final timing closure depends on the selected device speed grade, logic mapping, and clocking architecture.
Communications Protocol Conversion
The APA750-PQ208 is well suited to protocol converters and serial-interface aggregation because its flash-based nonvolatile configuration supports persistent programmable logic and its large I/O count accommodates multiple channels. The 147,456 bits of RAM can implement FIFOs, packet buffers, and state machines, while the gate capacity supports framing, error handling, and clock-domain logic. Engineers should use the family architecture information to plan clocking, resets, configuration access, and I/O standards before finalizing the conversion topology.
Instrumentation and Test Systems
In instrumentation, the APA750-PQ208 can combine acquisition control, timing generation, status reporting, and communication logic in one programmable device. Its 158 user I/Os allow connection to sensors, relays, counters, display controllers, and test fixtures, while 147,456 bits of RAM can buffer measurement sequences. The nonvolatile flash configuration also supports field updates of instrument firmware and logic revisions. Thermal, power, and signal-integrity checks should be completed for each specific instrument architecture.
Embedded Storage and DMA Controllers
The APA750-PQ208 can serve as a custom DMA engine, storage-interface controller, or embedded data mover because the 750,000-system-gate density accommodates control logic alongside the 147,456 bits of on-chip RAM. Programmable I/Os can connect the controller to external memories and peripheral buses, with the SRAM used for queues, descriptors, and burst buffers. The design must account for synchronous memory timing, address decoding, arbitration, and clock-domain crossings while preserving the device's specified 2.3 V to 2.7 V supply range.

设计说明
Design the core supply for the stated 2.3 V to 2.7 V operating range and verify startup, load-current, and power-supply sequencing behavior against the manufacturer electrical limits. Keep the 2.5 V-class rail quiet enough for the logic implementation and check the actual switching activity in the final design. Estimated: power dissipation equals the selected core operating voltage multiplied by the total core current; calculate this value with the actual resource utilization and operating frequency rather than using a nominal gate count.
Route the 208-pin PQFP footprint according to the manufacturer package drawing, including lead pitch, pad length, solder-mask clearance, and exposed thermal or supply-pin requirements. Place decoupling capacitors near the relevant power pins and keep the return path continuous for every supply and ground connection. Because this is a high pin-count programmable-logic package, use a PCB assembly process capable of fine-pitch QFP inspection and verify pin 1 orientation before reflow.
Use the device's clock resources and define clock-domain boundaries before assigning general-purpose I/O. Dedicated clock, configuration, reset, and user-I/O functions must be assigned from the package pin table, and any interface requiring a specific I/O standard should be checked for voltage compatibility. Place series termination or other source-termination components only after the manufacturer input and output characteristics for the assigned pin have been reviewed.
Do not treat the 750,000-system-gate figure as a direct substitute for logic-cell count, and do not infer RAM or I/O availability from another APA suffix. Confirm the device identifiers, speed grade, temperature profile, configuration method, and pin functions in the manufacturer documentation. For a replacement, compare the complete pin-description table and verify that the required design fits the available resources rather than relying only on the package name.
