A54SX08-2PQG208 Übersicht
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer wires together after manufacturing, sitting in the hierarchy below ASICs and above CPLDs in gate density. The SX family uses a patented metal-to-metal antifuse programmable interconnect, which means configuration data is permanent: unlike SRAM FPGAs, no configuration PROM or boot sequence is required, and the programmed bitstream is inherently secure and single-event-immune compared to volatile architectures.
Key features include approximately 130 user I/Os on the 208-pin package, 768 configurable logic modules, dual-rail operation at 3V~3.6V and 4.75V~5.25V, and fast pin-to-pin timing that simplifies system interfacing. The 0.35um CMOS process delivers deterministic, routing-independent delays, a hallmark of the SX architecture that appeals to designers migrating ASIC or PAL/GAL designs.
Typical applications include industrial control logic, glue logic integration and system consolidation, telecommunications line-card control, and legacy avionics or defense hardware sustainment where the one-time-programmable antifuse is preferred over SRAM reprogrammability.
Designers should note that this commercial-temperature-grade part (0C to +70C) is factory-programmed by the manufacturer using the Designer software netlist flow, so the design must be finalized before ordering. Pin-to-pin family migration within the SX/SX-A/SX-S lines in the same 208-PQFP footprint allows gate-count upgrades without board redesign.

Typische Anwendungen

Industrial Control and Glue Logic Consolidation
The A54SX08-2PQG208's 8,000 gates, 512 logic modules and 130 user I/Os make it well suited to replacing dozens of 74-series TTL PAL/GAL devices on an industrial control board. Its dual-supply operation (4.75V~5.25V rail) interfaces directly with legacy 5V sensors and PLC peripherals, while deterministic antifuse routing delays simplify meeting fixed scan-cycle timing. Because the design is one-time-programmed at the factory, production units behave identically with no configuration device to fail in electrically noisy factory environments. Consolidating random logic into a single 208-PQFP reduces board area, BOM count and assembly cost. Trade-off: design changes require a new programmed part order, so reserve this part for mature, frozen control logic rather than iterative prototyping.
Empfohlen
Telecommunications Line-Card Control
In telecom line cards, the A54SX08-2PQG208 provides framing, alarm monitoring and backplane interface logic where instant-on operation matters: antifuse configuration is present at power-up, eliminating the boot delay of SRAM FPGAs during hot-swap events. The 320 MHz maximum system frequency comfortably covers T1/E1 and SONET-overhead glue functions, and pin-to-pin timing allows the FPGA to sit directly in data paths without hold-time workarounds. Its 130 user I/Os in the 28x28 mm 208-PQFP suit dense line-card layouts with 3.3V backplane signaling. Designers should budget supply sequencing between the 3.3V and 5V rails and verify surge immunity on backplane-facing pins with TVS protection. Obsolete status makes this a sustainment play: replace failed cards or migrate to SX16P footprints in maintenance releases.
Empfohlen
Legacy Avionics and Defense Sustainment
Although not radiation hardened, the A54SX08-2PQG208's antifuse technology is inherently immune to configuration upset because no stored configuration memory exists to corrupt, a property valued in defense and avionics sustainment programs extending service life of fielded equipment. One-time programming prevents design theft and eliminates configuration-device single points of failure in safety-related logic. The commercial 0C to +70C rating restricts use to controlled-cabin or ground equipment; external-temperature platforms should instead evaluate the I-grade variants or Microchip RTAX radiation-tolerant FPGAs (e.g., RTAX250SL-CQ208V, same 208-pin QFP family). Migration within the SX/SX-A family in the PQ208 footprint requires only netlist recompilation. Verify documented die-lot traceability with the supplier, as broker stock varies in age.
Empfohlen
ASIC Prototyping and Emulation
Historically, SX-family FPGAs served as low-cost ASIC prototyping vehicles because their deterministic antifuse routing made timing results transferable to gate-array implementations. With 8,000 gates and 512 modules, the A54SX08-2PQG208 accommodates medium-size control blocks, state machines and bus interfaces for pre-silicon verification. The 320 MHz ceiling covers system-speed emulation of many 0.35um-era ASIC blocks, and the 130 user I/Os support wide stimulus/probe buses in the 208-PQFP socket-friendly package. For teams maintaining legacy test benches still fitted with SX08 hardware, this part keeps those rigs alive. Note that netlist imports must go through Actel Designer format conversion, and antifuse one-time programming means each design iteration consumes a fresh device - budget accordingly for multi-iteration verification.
Empfohlen
Test and Measurement Equipment
Bench instruments and ATE fixtures benefit from the A54SX08-2PQG208 as timing-generation and capture logic: deterministic antifuse delays give repeatable trigger alignment that SRAM FPGA re-route variance does not, supporting measurement repeatability across instrument units. The 320 MHz system performance covers counter/timer and pattern-generator front-end functions, while 5V-tolerant I/O on the 4.75V~5.25V rail connects directly to legacy instrument buses and relay-driver logic without level shifters. The 208-PQFP 28x28 mm package fits standard test-fixture footprints with hand-solderable 0.65 mm pitch leads for field repair. Because the part is factory-programmed, service organizations can stock pre-programmed spares interchangeably. Watch MSL3 moisture handling during any rework: bake per J-STD before soldering to avoid package delamination.
Empfohlen
Secure Embedded Control Systems
Applications requiring firmware confidentiality use the A54SX08-2PQG208 because antifuse programming data cannot be read back or probed: the design lives only as metal-to-metal links inside the die. This contrasts sharply with SRAM FPGAs whose bitstreams must be encrypted and still expose attack surface at boot. With 8,000 gates, the device implements license-check logic, key-handling state machines, and tamper-response glue for embedded controllers, with instant-on operation removing the window during which a volatile FPGA would be unconfigured. The 0C~70C rating and non-radiation-hardened status confine it to commercial-grade secure products. Designers should still apply board-level tamper measures, since silicon reverse-engineering of 0.35um antifuse devices, though difficult, is not impossible. Plan lifetime buys now given obsolete status.

- Dual 3.3V/5V supply operation (vs. A54SX16P-PQG208)
Designhinweise
Estimated: the SX08 in the PQ208 package draws its core from the 3V~3.6V rail (or 4.75V~5.25V rail option) plus an I/O rail; total power is dominated by I/O switching, not core static current, because antifuse interconnect has no configuration-cell leakage. Budget decoupling of at least 0.1uF per VCC/VPP pin pair plus one 10uF bulk capacitor per rail. The programming pins (VPP) must be tied per the 54SX datasheet operating-condition table once the device returns from Microsemi factory programming - do not drive them during normal operation.
The 208-PQFP uses 0.65 mm lead pitch on a 28x28 mm body; fan out with 0.2 mm trace/0.2 mm space through two via rows under the body to inner layers. Provide a solid ground plane directly under the die area to return the fast 320 MHz-class edges, and keep clock and high-fanout nets on short, direct routes to limit reflection on 5V-tolerant I/O. MSL 3 (168 hours) requires dry storage; bake per J-STD handling if the moisture barrier bag is opened before reflow.
The most frequent mistake with this obsolete part is treating it as reprogrammable: it is one-time programmable at the factory, so any design change requires ordering newly programmed devices with updated netlists - order last-time-buy quantities with margin. Second, do not assume pin compatibility blindly: SX16/SX32 in PQ208 share the footprint but I/O ring assignments differ slightly; re-verify pinout and recompile in Microchip (Actel) Designer software before any drop-in migration. Third, this is a commercial-temperature part - never substitute it into I-grade sockets.
