APA300-PQ208 - 300K-Gate Flash FPGA | Microchip Technology
MPN: APA300-PQ208 ✗ Cuối đờiAPA300-PQ208 Tóm tắt
A field-programmable gate array, or FPGA, is a programmable-logic semiconductor in which configurable logic blocks and programmable interconnect form a user-defined digital circuit. An FPGA belongs to the programmable-logic device hierarchy alongside complex programmable logic devices and programmable SoCs. Flash-based FPGAs retain their programmed configuration in nonvolatile memory, allowing the circuit to operate at power-up without a separate configuration load.
The APA300 family combines reprogrammability with an ASIC-oriented design flow. Its key attributes include nonvolatile Flash configuration, 300,000 system gates, 158 configurable user I/O pins, and 73,728 bits of on-chip RAM. The device supports 2.3 V to 2.7 V operation and uses a 0.22 µm CMOS process. Its programmable architecture is suited to designs requiring flexible logic density, rapid design revisions, and field update capability.
Technical operation combines configurable logic elements, dedicated memory resources, programmable routing, and user I/O. The ProASICPLUS architecture emphasizes low-skew global networks, long-line routing, split global networks, high routability, high utilization, and Schmitt-trigger input support. These characteristics make the device useful for control logic, interface consolidation, protocol bridging, and embedded system functions requiring deterministic programmable routing.
Typical applications include industrial automation controllers, communications interfaces, data-acquisition systems, embedded control platforms, test equipment, and high-reliability peripheral logic. The 180 MHz performance class supports clocked control logic and moderately complex parallel processing, while the 73,728-bit RAM allows buffering, packet storage, and state retention without external memory in many designs.
Designers should assign pins using the manufacturer pin-description tables and preserve the device's specified power-supply, decoupling, and configuration requirements. Differential clocks, high-speed memories, and wide buses should be reviewed for routing and timing closure because the 208-pin PQFP package has fixed leads and less routing flexibility than a modern fine-pitch BGA.
This page combines the manufacturer family information, package and resource details, practical implementation guidance, and same-footprint replacement analysis to support faster FPGA selection and PCB planning.

Industrial Automation Controllers
The APA300-PQ208 fits machine-control logic that coordinates sensors, actuators, interlocks, and sequencing functions. Its 300,000 system gates, 8,192 logic cells, and 158 configurable I/O pins provide substantial capacity for combining parallel I/O handling, state machines, and communications interfaces in one device. The 2.3 V to 2.7 V operating range supports compact embedded control boards, while nonvolatile Flash configuration allows the controller to resume its programmed logic at power-up. Designers should select the ordering suffix appropriate for the required operating temperature and industrial qualification conditions.

Communications Protocol Interfaces
APA300-PQ208 is suitable for protocol framing, command parsing, data buffering, and supervisory logic in communications equipment. The device combines 73,728 bits of on-chip RAM with 8,192 logic cells, allowing designers to implement packet buffers and finite-state machines without immediately adding external memory. Its 180 MHz performance class supports moderately clocked parallel logic, while Flash configuration supports deterministic startup and field updates. For high-speed links, engineers should constrain transitions, apply suitable I/O standards, and complete timing analysis for every registered interface.

Data Acquisition and Signal Conditioning
The APA300-PQ208 can consolidate acquisition sequencing, channel control, digital filtering, and data-transfer logic around external converters. Its 158 configurable I/O pins allow parallel ADC and DAC interfaces, capture triggers, status flags, and control signals to be placed within one programmable device, while 73,728 bits of RAM can provide local buffering for short data bursts. The 180 MHz class supports clocked state machines and moderate pipeline processing. Designers should define acquisition timing, constrain input timing, and avoid using general I/O as a substitute for dedicated clock or configuration functions.

Embedded Test and Measurement
APA300-PQ208 can serve as the programmable control and measurement engine in compact test systems that coordinate stimulus, capture timing, pass/fail logic, and data formatting. The 300,000 system gates and 8,192 logic cells support parallel channel control and instrument-state sequencing, while nonvolatile Flash enables repeatable operation after power-up. The 73,728-bit RAM is useful for short result buffers but not large waveform storage. Instrument designers should use controlled clocking, account for analog-to-digital conversion latency, and separate sensitive measurement paths from digital switching activity.

Automotive Peripheral Logic
APA300-PQ208 can consolidate vehicle peripheral functions, diagnostic interfaces, and subsystem control when the selected ordering grade satisfies the application's environmental requirements. The programmable Flash architecture allows logic revisions without changing the PCB, and live power-up operation supports predictable subsystem startup. Its 158 configurable I/O pins are valuable for body, comfort, or accessory modules that combine discrete inputs and outputs with protocol logic. Automotive programs must additionally verify temperature range, electromagnetic compatibility, shock, vibration, and supplier-specific qualification for the exact suffix.

APA300-PQ208 is applicable to access-control panels, credential readers, alarm controllers, and distributed security interfaces where deterministic logic and field programmability are important. Its 158 user I/O pins support keypad scanning, indicator control, door sensors, relay drives, and bus transceiver interfacing, while Flash configuration retains the programmed system behavior across power cycles. The 73,728 bits of RAM are sufficient for short event buffers or protocol state. Security engineers should protect configuration access, validate external inputs, and isolate sensitive interfaces according to the product's system threat model.

Ghi chú thiết kế
Design the 2.3 V to 2.7 V supply network for both steady-state and configuration-current demands. Place the manufacturer-recommended bypass capacitors directly beside the supply and ground pins, minimize loop area, and keep the return path through the associated ground plane. Confirm the operating-voltage requirement of the exact APA300-PQ208 ordering grade and any temperature-dependent limits before selecting regulator headroom.
Use the manufacturer package drawing and pin-description table to create the PQFP-208 footprint. Preserve pin-1 orientation, verify lead pitch against the physical sample, and reserve access for programming or test features. Because the package exposes a large number of dedicated and configurable pins, do not infer signal functions from location alone; assign every pin from the official pin table before releasing the PCB.
Apply timing constraints to clock inputs, external interfaces, and any source-synchronous paths. Route clocks over continuous reference planes, avoid unnecessary stubs, and keep switching nets away from sensitive analog inputs. The ProASICPLUS global network supports predictable clock distribution, but board-level success still depends on controlled impedance, clean return paths, and correct I/O-standard settings.
Do not treat a matching 208-pin package as proof of complete interchangeability. Review configuration pins, dedicated clocks, I/O standards, supply limits, speed grade, temperature range, and qualification for each suffix. The APA300-PQ208A, APA300-PQ208I, APA300-PQG208M, and APA300-PQG208I alternatives share the relevant family footprint, but only APA300-PQ208A is explicitly documented with the same 300,000-gate and 180 MHz performance values in the comparison data.
Estimate junction temperature from the device's actual supply voltage, output-current demand, programmed utilization, and the manufacturer's thermal characterization. The legacy 0.22 µm PQFP-208 package can dissipate meaningful heat in dense, high-activity designs even though its exposed leads assist heat transfer. Provide uninterrupted ground-plane area beneath the device and keep high-current paths outside the FPGA's thermal region when the board outline permits.
