APA450-PQ208 - 450K-Gate ProASICPLUS FPGA | Microchip
MPN： APA450-PQ208 ✗ 停產APA450-PQ208 概覽
An FPGA is a reprogrammable semiconductor containing configurable logic blocks, programmable interconnect, memory, and I/O resources. A field-programmable gate array belongs to the broader programmable-logic hierarchy, which includes complex programmable logic devices, programmable logic arrays, and application-specific integrated circuits. The ProASICPLUS family combines nonvolatile Flash configuration with FPGA implementation flexibility, allowing a programmed design to retain its configuration without a separate configuration memory device.
The APA450-PQ208 provides 12,288 programmable logic cells, 450,000 system gates, and 110,592 RAM bits for digital control, data processing, interface bridging, and embedded system logic. Its 158 programmable I/O pins support substantial external connectivity, while the 208-BFQFP package provides 0.5 mm pitch connectivity for high-density programmable-logic boards. Published device information also identifies CMOS technology and up to 180 MHz device performance for the APA450 family.
This ProASICPLUS device is intended for designs requiring programmable logic density, nonvolatile configuration, and a substantial number of user I/O resources. Its 450,000 system gates make it more suitable than smaller PLDs for consolidated control logic, protocol handling, and multi-module digital subsystems. System designers should use the manufacturer’s pin-description table and device documentation when assigning signals because a 208-pin programmable-logic package requires exact power, configuration, clock, and user-I/O connections.
Typical uses include industrial automation controllers, communications interface modules, embedded data-acquisition systems, instrumentation, test equipment, and embedded processing peripherals. In these systems, the FPGA can implement parallel logic, protocol engines, state machines, and fixed-function digital pipelines while retaining field programmability for design updates.
Power-supply layout is especially important because the specified 2.3 V to 2.7 V operating range leaves only 400 mV of total nominal supply headroom. Decoupling should follow the manufacturer’s recommended values and placement guidance, while clock, configuration, and high-speed interface routing should preserve signal integrity. The 0 °C to 70 °C rating also requires thermal design that keeps the device within its specified ambient range.
This product page combines the manufacturer’s ProASICPLUS family information with distributor package details, package-compatible alternatives, application guidance, and design notes. It helps engineers identify the correct device for a 450K-system-gate design while distinguishing true package-compatible replacements from alternatives that require a different footprint or redesign.

主要差異化特點
- Commercial-temperature ordering option with full ProASICPLUS capacity (對比APA450-PQ208I)
- Documented package-compatible substitution path (對比APA450-PQG208)
- Automotive-ordering option without a footprint change (對比APA450-PQ208A)
設計說明
Use a low-noise supply that remains within the 2.3 V to 2.7 V operating range across temperature, load, and tolerance. Place the required bypass capacitors close to the corresponding power and ground pins, and provide an uninterrupted return path beneath the device where the package and board construction permit. Because the specified range provides only 400 mV of total nominal headroom, regulator output tolerance and transient ripple must be included in the worst-case power budget.
Build the PCB footprint from the official 208-BFQFP package drawing rather than a generic 208-pin PQFP footprint. Confirm land pattern, exposed or non-exposed pad construction, pin numbering, solder mask clearance, and assembly orientation against the exact ordering code. The 0.5 mm pitch demands accurate component placement and adequate soldering-process capability; verify all 158 user I/O assignments and dedicated pins in the manufacturer pin-description table before release.
Route configuration, clock, and high-speed user signals with continuous reference planes and avoid unnecessary stubs or long parallel runs. Place clock and data-source components so that switching current loops remain small, and keep the FPGA’s supply and ground connections close to the package. Use the manufacturer’s timing and pin guidance to identify dedicated clock inputs, configuration pins, and any output or bidirectional pins that require controlled external termination.
Do not assume that similar APA450 order codes are automatically interchangeable in every production context. APA450-PQ208I, APA450-PQG208, and APA450-PQ208A share the documented PQFP-208 format, but temperature grade, qualification, ordering status, programming support, and procurement requirements still require confirmation. Before substitution, compare the complete ordering codes, pin tables, timing characteristics, and configuration requirements against the Microchip manufacturer documentation.
