A54SX16P-2PQG208 概要
An FPGA (field programmable gate array) is a semiconductor device containing a fabric of configurable logic blocks (CLBs) and programmable interconnects that the designer programs after manufacturing. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs), above CPLDs and SPLDs in density, and are used to implement custom digital logic without the cost and lead time of an ASIC.
Key features of the A54SX16P-2PQG208 include its sea-of-modules architecture, which delivers performance and integration levels that Actel (now Microchip) stated were unmatched by other FPGA architectures at launch, 1452 configurable logic modules, and a CMOS process for low power consumption. The -2 speed grade supports clock frequencies up to 320 MHz, making the device suitable for performance-intensive glueless logic integration.
Technically, the SX family uses a sea-of-modules architecture rather than the traditional island-style LUT fabric. Each module is a compact logic element that can implement combinatorial or sequential functions with predictable routing delays, simplifying timing closure. The 'P' suffix denotes the standard commercial temperature/processing variant; the '2' is the speed grade; and PQG208 identifies the 208-lead quad flatpack.
Typical applications include industrial control and automation, telecommunications and networking line-card logic, high-speed bus bridging, test and measurement instrumentation, and military/aerospace system logic where one-time-programmable antifuse-style reliability and low power were historically valued.
When designing with this device, verify the 208-pin PQFP thermal and electrical constraints, use proper decoupling on all VCC/VPP pins, and note that the design is programmed via the Actel/Microchip Libero design flow. Because PQFP lead pitch is 0.50 mm, careful PCB land-pattern control is required.

主な用途
A54SX16P-2PQG208 の用途: 6 件s: Industrial Control and Automation, Telecommunications and Networking Line Cards, Test and Measurement Instrumentation, Aerospace and Defense System Logic, Embedded Processing Coprocessor / Glue Logic, Wireless and RF Digital Baseband Control.
Industrial Control and Automation
The A54SX16P-2PQG208 fits industrial control and factory automation logic where 24,000 system gates and 175 user I/O are sufficient for sequencers, encoders, motion-interface glue logic, and safety interlock state machines. The SX sea-of-modules architecture gives deterministic, predictable routing delays, which simplifies timing closure for cycle-accurate control loops, while CMOS technology keeps power low in enclosed cabinets. Its -2 speed grade supports clocking well beyond typical PLC backplane rates (up to 320 MHz class), providing headroom. Deploy it between a microprocessor and field I/O, using the wide 175-I/O bank for parallel buses and discrete sensing, with the 208-pin PQFP offering robust through-reliability on vibration-prone industrial PCBs.
おすすめ
Telecommunications and Networking Line Cards
In telecom and networking line-card designs, the A54SX16P-2PQG208 implements bus bridging, framing, and backplane interface glue logic at speed grades suited to the 320 MHz class of the SX -2 device. The 175 available I/O accommodate wide parallel data paths toward PHYs, framers, and backplane connectors, while the sea-of-modules fabric provides the timing predictability required for synchronous line-rate logic. Because SX routing delays are deterministic, designers can meet fixed-backplane timing budgets without extensive iterative routing. Place the FPGA between a processor and serial transceivers; the 208-pin PQFP with 0.50 mm pitch is manufacturable on standard reflow lines. For higher density later, the A54SX32-2PQG208I upgrades the design on the same footprint.
おすすめ
Test and Measurement Instrumentation
The A54SX16P-2PQG208 serves bench and automated test equipment as trigger logic, counter/timer fabric, and bus interface glue. Its 24K system gates accommodate state machines, edge detectors, and timebase dividers, while the 320 MHz -2 speed grade supports high-resolution event timing in counters and pulse generators. The 175 user I/O directly interface front-panel digitizers, relay multiplexers, and processor buses without external fanout logic. The SX architecture's deterministic routing helps maintain consistent propagation delay across trigger channels - a key metrology concern. Use the 208-pin PQFP in the instrument's main board with local decoupling on every supply pin; verify calibration-related timing constants after place-and-route in the Libero static timing reports.
おすすめ
Aerospace and Defense System Logic
Actel/Microchip SX FPGAs, including the A54SX16P-2PQG208, are widely deployed in defense electronics for command decode, bus-interface glue, and payload sequencing, building on the family's heritage in high-reliability programs. The CMOS sea-of-modules fabric with its deterministic timing suits deterministic flight-logic paths, and the 175 I/O supports MIL-STD-style parallel bus interfaces and discrete command/status lines. In this domain the related RTAX series extends the SX architecture to radiation-tolerant grades, making prototype work on the commercial A54SX16P straightforward before migration. The 208-pin PQFP package is compatible with standard soldering processes and inspection. Verify screening, temperature class, and documentation requirements against the applicable program specification before use.
おすすめ
Embedded Processing Coprocessor / Glue Logic
As a coprocessor glue device, the A54SX16P-2PQG208 offloads host microcontrollers or DSPs of address decoding, wait-state generation, interrupt collection, and parallel-bus multiplexing. With 24K system gates and 1452 logic modules, it can integrate dozens of discrete 74-series functions into one CMOS device, cutting board area, BOM count, and power. The 175 I/O cover full 32-bit address/data buses plus control strobes and general-purpose flags. The -2 speed grade's 320 MHz class performance far exceeds microprocessor bus timing needs, so the FPGA never limits access times; instead, design effort goes into setup/hold timing around the host interface, verified in Libero timing analysis. The industrial-temperature A54SX16P-2PQG208I variant extends this use to harsh embedded environments.
おすすめ
Wireless and RF Digital Baseband Control
The A54SX16P-2PQG208 provides digital control for RF modules and wireless subsystems: synthesizer programming, AGC state machines, T/R switching sequencing, and telemetry formatting. Its 24K gates and 175 I/O interface directly to devices such as the TDA5xxx transceiver family, taking over timing-critical control that would burden an MCU. The -2 grade's 320 MHz class performance supports fast settling sequences, while CMOS power consumption minimizes noise and thermal load near sensitive RF sections. Keep the FPGA physically separated from VCO/PLL circuitry and use solid ground planes to contain switching noise; the deterministic SX routing eases implementation of fixed-latency control paths. Industrial-temperature variants (A54SX16P-2PQG208I) cover outdoor radio deployments.

設計ノート
The A54SX16P-2PQG208 comes in a 208-lead BFQFP/PQFP with 0.50 mm lead pitch and a 28 x 28 x 3.4 mm body. Follow the exact land pattern in the Microchip SX family datasheet package section; with 0.50 mm pitch, stencil aperture design and paste volume control matter to avoid bridging. Inspect with 100% AOI or X-ray on the outer rows. The tray packaging (Newark lists tray form) requires careful handling of leads - check coplanarity before reflow.
Decouple every VCC and programming-supply pin with local 0.1 uF ceramic capacitors, complemented by bulk 10 uF capacitance near the device, per standard SX-family power guidance in the datasheet. Because this CMOS FPGA drives up to 175 I/O simultaneously, ground bounce and simultaneous-switching noise can corrupt quiet rows - use a solid ground plane and dedicate power islands. Estimated: with tens of mA per switching I/O bank, transient currents can reach amp-class peaks at 320 MHz-class edges, so low-inductance vias on each decoupling capacitor are mandatory.
Do not confuse suffix fields: 'P' (die/temperature variant), '-2' (speed grade), 'I' (industrial temperature) - ordering the wrong temperature grade is the most common substitution error in the SX16P PQ208 family. Also confirm the speed grade supports your timing closure: designs that barely meet timing on the -2 grade will fail on -1 or standard grades. Re-run static timing analysis in Libero after any grade substitution, and verify unused-I/O termination settings per the datasheet to avoid floating inputs.
