A54SX16A-PQG208I Übersicht
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements digital logic through programmable interconnect and logic blocks, sitting within the broader programmable logic hierarchy: FPGA -> programmable logic device -> digital IC -> semiconductor. The SX-A family uses antifuse programming technology, in which connections are permanently set at programming time. This gives the A54SX16A a non-volatile, configuration-storage-free fabric with no external boot PROM, low power consumption, and inherent resistance to configuration readback attacks.
Key features include 16K typical usable gates (approximately 24,000 system gates), 924 logic modules built around multiplexer-based combinational cells, 175 user-input/output pins in the 208-pin QFP, a 2.5V core operating from a 2.25V to 2.75V range, and industrial temperature operation (-40C to +85C) indicated by the I suffix. The 0.25 um process supports system speeds up to 227 MHz toggle frequency, adequate for glue logic, bus interfacing, state machines, and address decoding at moderate clock rates.
Architecturally, SX-A devices place routing resources in the top two metal layers above the logic modules, optimizing silicon area and giving predictable, low-skew interconnect. Because the antifuse fabric is one-time programmable, designs are immune to configuration-stream corruption and require no configuration controller, reducing bill-of-materials count versus SRAM FPGAs.
Typical applications include industrial control and automation, telecommunications line-card glue logic, aerospace and defense systems requiring non-volatile, secure programmable logic, and legacy board designs where the SX-A family remains the qualified choice.
Designers should plan the pinout and one-time programming budget carefully: unlike SRAM FPGAs, an antifuse device cannot be reprogrammed after metal fuses are blown, so functional verification before programming is essential. The PQFP package requires careful PCB land-pattern design for fine 0.5 mm pitch leads.

Typische Anwendungen
A54SX16A-PQG208I ist geeignet für 6 Anwendungs: Industrial Control and Automation, Telecommunications Line-Card Glue Logic, Aerospace and Defense Secure Logic, Legacy Board Sustainment and Repair, Test and Measurement Instrument Logic, Embedded Coprocessor and Bus Bridge.
Industrial Control and Automation
The A54SX16A-PQG208I fits industrial control boards that need deterministic glue logic such as PLC I/O decoding, motor-controller interface logic, and backplane arbitration. Its 175 user I/O pins in a 208-pin PQFP provide ample parallel interface capability, while the 227 MHz toggle capability comfortably covers typical industrial clock domains of 25-100 MHz. The antifuse fabric powers up instantly with no configuration time, a meaningful benefit in factory equipment expected to be operational within milliseconds of power application. Because the 2.5V core draws low static current and the part needs no boot flash, board power budgets and BOM count shrink. The industrial -40C to +85C rating of the I-suffix part matches unconditioned factory-floor cabinets.

Telecommunications Line-Card Glue Logic
Telecom line cards historically used SX-A devices for bus bridging, framing-logic assist, and address decode between physical-layer devices and backplane controllers. The A54SX16A-PQG208I provides 924 logic modules, enough for complex decode trees, counters, and handshaking state machines, while its top-layer metal routing keeps interconnect skew predictable for synchronous backplane timing. The non-volatile antifuse fabric eliminates the configuration controller and serial flash that SRAM FPGAs require on slot cards, freeing board area and removing a failure point. With a 2.5V core and low static power, thermal load on dense line cards stays minimal. The 208-pin PQFP's 0.5 mm pitch is compatible with standard telecom PCB assembly processes.
Empfohlen
Aerospace and Defense Secure Logic
Defense and aerospace designers select the A54SX16A-PQG208I because antifuse FPGAs offer no configuration bitstream to intercept or corrupt, and the M-suffix screened variants (e.g., A54SX16A-PQG208M) exist for high-reliability programs. The design is fixed at programming time, which simplifies configuration management and verification for flight hardware, and there is no risk of SEU-induced configuration upset of the programming layer. The 16K-gate capacity suits payload interface logic, telemetry encoding assists, and redundancy-management circuits. Industrial and screened temperature options cover the -40C to +85C and extended ranges typical of avionics bays. Designers should complete full functional simulation before programming because the antifuse array is one-time programmable.
Empfohlen
Legacy Board Sustainment and Repair
Many fielded industrial and telecom boards were designed around SX-A devices, and the A54SX16A-PQG208I remains the qualified sustainment part for those assemblies. Because the SX-A family is still active at Microchip, repair depots can obtain new, lead-free stock rather than scavenging used parts, and the -2 and -1 speed-grade variants in the identical 208-pin PQFP allow substitution when a specific grade is out of stock. The antifuse fabric also means a replacement device must be reprogrammed with the original design file; depots should retain Libero/Designer project archives and programming station access. The 2.5V supply is unchanged across the family, so power supply design on legacy boards needs no modification.
Empfohlen
Test and Measurement Instrument Logic
Bench and automated test instruments use the A54SX16A-PQG208I for counter/timer assist logic, relay-driver sequencing, trigger distribution, and IEEE-style bus interfacing. The 227 MHz toggle capability supports high-resolution counter front ends, and the 175 user I/O allow wide parallel capture paths to a microprocessor. Deterministic, configuration-free power-up means the instrument is ready before the operator finishes startup, an ergonomic plus. The antifuse fabric adds no configuration jitter or reconfiguration pauses during long automated test runs. The PQFP's gull-wing leads simplify rework on instrument mainboards compared with BGA alternatives, lowering total cost of ownership for low-volume instrument production and field service.
Empfohlen
Embedded Coprocessor and Bus Bridge
Embedded systems use the A54SX16A-PQG208I as a fixed-function coprocessor bridging a microprocessor bus to peripherals: DMA handshaking, wait-state generation, chip-select expansion, and protocol conversion between legacy parallel buses and newer interfaces. The 924 logic modules implement multi-channel handshaking engines with predictable timing because antifuse interconnect does not change between programming runs, making timing sign-off a one-time effort. Instant-on behavior lets the bridge be functional before the CPU finishes reset, avoiding bus faults during boot. At 2.5V core with low static draw, the device suits battery-backed and always-on data loggers. Designers should budget the one-time programming cost per unit into production economics.

Wichtigste Unterscheidungsmerkmale
- Non-volatile single-chip operation (vs. A54SX16A-2PQG208I (and all SRAM FPGAs))
- Cost advantage over faster speed grades (vs. A54SX16A-2PQG208I)
- Industrial temperature rating (vs. A54SX16A-2PQG208)
Designhinweise
The A54SX16A is a one-time-programmable antifuse FPGA: once programmed, the device cannot be erased or reprogrammed. Complete full functional simulation and timing verification in Microchip Libero/Designer (with appropriate SDF back-annotation) before committing a device to programming. Ordering the wrong speed grade or discovering a functional bug after programming consumes hardware irreversibly. Prototype with the faster -2 grade when schedule allows, since a -2 part can be used anywhere a standard-grade part fits, but not the reverse.
The A54SX16A-PQG208I runs from a 2.5V core (2.25V to 2.75V per family datasheet). Decouple VCC and the programming supply pins with at least 0.1 uF ceramic capacitors at each supply pin pair plus bulk capacitance near the device. Static current is low for antifuse FPGAs, but dynamic current scales with toggle rate; estimate Icc using the Microchip power calculator for your design before finalizing the 2.5V regulator rating. Ensure supply ramp is monotonic per datasheet power-up requirements.
The 208-pin PQFP has 0.5 mm lead pitch with gull-wing leads. Follow the datasheet land-pattern recommendation and use solder paste inspection on first articles, as fine-pitch QFPs are prone to bridging. Provide at least two ground planes or a solid ground pour under the device for signal return, and keep fast switching I/O stubs short. Estimate thermal performance with the family datasheet theta-JA for the 208-pin QFP; dissipation is modest at 2.5V but verify for high toggle-rate designs.
