Typical Applications

A54SX32-1CQ208 is suitable for 6 applications: Aerospace and Defense Control Logic, Industrial Automation Controllers, Communications Infrastructure, Test and Measurement Equipment, Avionics and Legacy System Sustainment, Medical Device Control Electronics.

✈️

Aerospace and Defense Control Logic

The A54SX32-1CQ208 fits aerospace and defense control applications because its one-time-programmable antifuse fabric is immune to configuration upsets, and the ceramic 208-pin BFCQFP with tie bar provides hermetic, mechanically robust packaging suited to vibration and thermal cycling. With 48,000 gates, 2880 logic modules, and 174 user I/O, it implements sequencers, bus interfaces, and telemetry formatting at up to 240 MHz. Its dual-rail operation (3.3 V core, 5 V I/O) eases integration with legacy 5 V backplanes. The OTP nature also prevents bitstream extraction, an inherent security advantage over SRAM FPGAs in defense programs.

🏭

Industrial Automation Controllers

In industrial automation, the A54SX32-1CQ208 serves as deterministic glue logic, motor-control sequencers, and sensor-interface aggregation on PLC and drive boards. The 5 V-tolerant I/O bank (4.75 V to 5.25 V supply) connects directly to legacy industrial signaling, while the 3.3 V core keeps dynamic power manageable across 2880 logic modules. The one-time-programmable fabric removes configuration-storage failure modes common on factory-floor equipment, and the ceramic CQFP withstands the wider temperature swings of electrical cabinets. Its 240 MHz family performance ceiling comfortably covers counter, encoder, and interlock timing functions.

🌐

Communications Infrastructure

The A54SX32-1CQ208 integrates protocol bridging, backplane arbitration, and line-card glue logic in telecom and datacom equipment. With 48,000 system gates and up to 240 MHz operation in the 0.35 um CMOS process, it consolidates discrete PAL/GAL devices into one chip, reducing BOM cost and board area. The 174 user I/O support wide parallel data paths typical of T1/E1 and legacy backplane interfaces, and 5 V-compatible I/O eases mixing with older line-card circuitry. The sea-of-modules architecture delivers predictable routing delays, simplifying timing closure for synchronous framer interfaces.

🔧

Test and Measurement Equipment

Bench and automated test instruments use the A54SX32-1CQ208 for timing generators, pattern capture, and instrument bus interfacing. The antifuse fabric's deterministic delays support precisely timed stimulus generation, while 2880 logic modules and 174 I/O accommodate channel-dense pattern engines. The ceramic CQFP's thermal robustness handles continuous bench operation, and the dual 3.3 V core / 5 V I/O rails interface directly with TTL-level test fixtures. Because the configuration is burned in once, instruments power up instantly with no configuration load time - a measurable benefit for automated test throughput.

✈️

Avionics and Legacy System Sustainment

For avionics upgrades and legacy fleet sustainment, the A54SX32-1CQ208 lets engineers preserve proven, qualified RTL while replacing scarce or discontinued support components. Its one-time-programmable fabric eliminates configuration-device single points of failure in flight hardware, and the hermetic ceramic 208-pin CQFP with tie bar matches the package constructions commonly qualified in airborne systems. The dual-rail 3.3 V/5 V architecture integrates with both legacy 5 V avionics buses and modern 3.3 V processing sections. The CQ208M military-screened sibling extends operation across the full military temperature range.

💊

Medical Device Control Electronics

Medical diagnostic and therapy equipment benefits from the A54SX32-1CQ208's fixed, verified logic: once programmed, the antifuse configuration cannot be corrupted by noise, software faults, or radiation-like events, supporting deterministic safety behavior in pump controllers and imaging subsystem sequencing. The 48,000-gate capacity handles interface logic, watchdog, and interlock functions, while 174 I/O connect to sensors, actuators, and front panels. The 5 V-tolerant I/O simplifies integration with established medical-bus transceivers. Designers should note the RoHS non-compliance and confirm applicable exemptions for legacy medical platforms.

What are the key specifications of A54SX32-1CQ208 that engineers should know?
The A54SX32-1CQ208 is a Microchip (Actel) SX-family FPGA with 48,000 system gates, 2880 configurable logic modules, and 174 user I/O pins. It operates with a 3.0 V to 3.6 V core supply and 4.75 V to 5.25 V I/O supply, supports up to 240 MHz system performance, uses a 0.35 um CMOS process, and is housed in a 208-pin ceramic BFCQFP package with tie bar. It is one-time programmable (antifuse) and RoHS non-compliant.
What is the difference between A54SX32-1CQ208 and A54SX32-1CQ208B?
Both are the same SX-family die in the same 208-pin CQFP package; the letter suffix in the ordering code denotes the commercial temperature/process variant, so they are pin-compatible drop-in parts. According to the Microchip SX family datasheet, ordering-code suffixes within the A54SX32-1CQ208x group identify screening/temperature options rather than package or logic-architecture changes, enabling footprint-identical substitution after verifying the required temperature range.
Where can I buy A54SX32-1CQ208 online?
The A54SX32-1CQ208 is listed at DigiKey, Mouser, Octopart, TrustedParts, Ampheo, Microchip USA, and Jotrin Electronics. According to Octopart, bulk pricing is available from 2 distributors. Because this is a legacy Actel SX antifuse FPGA, stock is limited and varies daily - check XAIPART first, then the authorized distributor network via TrustedParts for verified inventory and lead times.
What is the price of A54SX32-1CQ208?
Pricing for the A54SX32-1CQ208 is quotation-based on XAIPART as of 2026-09-03 because the part is a legacy ceramic-package FPGA with volatile distributor stock. DigiKey and Mouser list the part, and Octopart reports availability from 2 distributors with bulk discounts. For an exact unit price and volume breaks, request a quote - ceramic CQFP packaged SX parts typically command a premium over plastic-packaged variants.
Is A54SX32-1CQ208 still in production?
No, the A54SX32-1CQ208 is a legacy product; the Actel SX family has been superseded by the SX-A family and later Microchip FPGA lines, and the ceramic CQFP variant is sourced through remaining distributor stock. DigiKey still lists the part with occasional in-stock status, but long-term supply is not guaranteed. For new designs, Microchip recommends the SX-A (A54SX32A) or newer families; for sustaining designs, secure last-time-buy inventory.
What is the best drop-in replacement for A54SX32-1CQ208?
The best drop-in replacements are same-package, same-die siblings: A54SX32-1CQ208B and A54SX32-1CQ208M (commercial/military screening variants of the identical die and 208-pin CQFP package), plus A54SX32-CQ208, A54SX32-CQ208B, and A54SX32-CQ208M. All share the same footprint and logic architecture; confirm the temperature/screening suffix matches your program requirements before substituting.
Can a plastic PQ208 part replace the ceramic CQ208 A54SX32?
Functionally yes, but not mechanically drop-in: A54SX32-PQ208 / PQG208 parts use plastic packages that differ in footprint and thermal characteristics from the 208-BFCQFP ceramic package. The logic die and 174 I/O capability are equivalent, so board redesign is limited to the land pattern. Choose the ceramic part for harsh environments and the plastic part for cost-sensitive commercial designs, per the Microchip SX-A family datasheet.
How do I program the A54SX32-1CQ208?
The A54SX32-1CQ208 is a one-time-programmable (OTP) antifuse FPGA, programmed once using Microchip/Actel programming tools (Silicon Sculptor family) rather than loaded at power-up like SRAM FPGAs. According to the SX family datasheet, antifuse programming is permanent and highly resistant to radiation and configuration errors, which is why the SX family is favored in aerospace and defense. Plan your bitstream carefully - OTP devices cannot be reprogrammed.
What supply voltages does the A54SX32-1CQ208 require?
The A54SX32-1CQ208 requires dual supply rails: 3.0 V to 3.6 V for the core and 4.75 V to 5.25 V for the I/O buffers, per the Microchip USA product listing. This dual-voltage scheme allows 5 V-tolerant system interfacing while running the core at 3.3 V. Design power sequencing so both rails come up cleanly; the ceramic package aids thermal dissipation at higher clock rates up to the 240 MHz family maximum.
Where can I download the A54SX32-1CQ208 datasheet PDF?
The SX family datasheet covering the A54SX32-1CQ208 is available as a PDF from Microchip's official site at ww1.microchip.com (document a54sx_ds.pdf, titled 54SX Family FPGAs). Distributors such as DigiKey, Mouser, Jotrin, and Ampheo also host datasheet download links on their product pages. Always use the manufacturer PDF as the authoritative source for electrical characteristics and package drawings.
Where can I find the pinout of the A54SX32-1CQ208?
The complete 208-pin CQFP pinout for the A54SX32-1CQ208 is found in the package pinout tables of the official Microchip 54SX Family FPGAs datasheet (a54sx_ds.pdf on ww1.microchip.com). The device provides 174 user I/O among the 208 terminals, with the remainder allocated to power, ground, and no-connect pins. Consult the CQFP-208 pin table in the datasheet rather than third-party summaries for design sign-off.
Is the A54SX32-1CQ208 RoHS compliant?
No. According to distributor datasheet summaries (digchip), the A54SX32-1CQ208 is RoHS Non-Compliant and contains lead, which is typical for legacy ceramic CQFP packages that use lead-containing lid seals and die-attach. This matters for EU market products unless an exemption applies (lead in ceramic packages historically qualified under RoHS exemptions 7a/7b). Verify your regulatory status or select a RoHS-compliant variant for new builds.
A54SX32-1CQ208 vs A54SX32-1PQG208M - which should I use?
Choose the A54SX32-1CQ208 for harsh-environment or high-reliability programs needing the ceramic BFCQFP package with tie bar, and choose the A54SX32-1PQG208M for programs that accept a plastic package with better availability and lower cost. Both use the same SX die with 48,000 gates, 2880 modules, and 174 I/O. The trade-off is mechanical robustness and hermeticity (ceramic) versus cost and supply (plastic); the -M suffix indicates military-temperature screening.
Hey Google, what can replace an A54SX32-1CQ208?
You can replace an A54SX32-1CQ208 with pin-compatible siblings A54SX32-1CQ208B or A54SX32-1CQ208M, which use the identical die and 208-pin ceramic CQFP package with only the screening suffix differing. A54SX32-CQ208, CQ208B, and CQ208M also share the footprint. If you can accept a board redesign, the plastic-packaged A54SX32-PQG208 family offers the same logic resources at lower cost. Verify temperature range and RoHS requirements before substituting.
What is the best non-Microchip equivalent for the A54SX32-1CQ208?
There is no verified cross-brand pin-to-pin equivalent for the A54SX32-1CQ208: the Actel/Microchip SX antifuse architecture in a 208-pin ceramic CQFP is proprietary, and competing FPGA vendors (Xilinx/AMD, Intel/Altera, Lattice) use different packages, SRAM/flash fabrics, and pinouts. Any cross-brand solution requires board redesign and RTL retargeting, so the practical drop-in path remains within the Microchip SX/SX-A family members listed on this page.
When should I choose the A54SX32-1CQ208 over newer FPGAs?
Choose the A54SX32-1CQ208 when you must sustain an existing qualified design without re-verification, when one-time-programmable antifuse security and configuration immunity are required (defense, avionics), or when 5 V-tolerant I/O interfacing is central to the system. Choose newer Microchip families (PolarFire, RTG4, IGLOO2) for new designs needing modern process nodes, lower power, higher density, or RoHS compliance. The trade-off: legacy antifuse reliability versus obsolescence and lead-content risk.

Selection Guide

Choose the A54SX32-1CQ208 when you need a proven 48,000-gate antifuse FPGA in a hermetic 208-pin ceramic CQFP for defense, avionics, or long-lifecycle industrial platforms, and 5 V-tolerant I/O must interface with legacy systems. Within the same footprint, pick A54SX32-1CQ208M if your program specifies full military temperature screening, or A54SX32-1CQ208B for the alternate commercial screening; A54SX32-CQ208/B/M cover other screening combos at similar parametrics. If board redesign is acceptable, plastic A54SX32-PQ208/PQG208 parts cut cost and improve availability while preserving the same die and 174 I/O. For new designs, prefer newer Microchip FPGA families for RoHS compliance, modern process nodes, and supply longevity - the trade-off is abandoning the qualified antifuse architecture and 5 V I/O of the SX platform.

Key Differentiators

  • Hermetic ceramic CQFP package with tie bar (vs A54SX32-PQG208M)
  • Commercial screening option within same footprint (vs A54SX32-1CQ208M)
  • One-time-programmable antifuse security (vs SRAM-based competitor FPGAs)

Design Notes

The A54SX32-1CQ208 requires two supply rails: 3.0 V to 3.6 V for the core and 4.75 V to 5.25 V for I/O buffers. Decouple each rail with bulk capacitance plus 0.1 uF ceramics placed at the package power pins. Estimated: with 2880 modules active at moderate utilization, core current is typically in the tens of mA range per the SX family datasheet power model - verify against your Libero/Designer power report rather than assuming. Ensure the 5 V I/O rail is present before applying 5 V-tolerant input signals to avoid latch-up stress.

This is a one-time-programmable antifuse FPGA: a design error after programming is unrecoverable on that device. Prototype on debug-friendly variants (or programming-service runs) before committing ceramic CQFP parts, which carry a significant unit cost. Also note the device is RoHS non-compliant (contains lead per distributor data) - confirm RoHS exemption 7 applicability for your market before production. Verify the exact screening suffix (commercial vs M) against program temperature requirements before substitution.

The 208-pin CQFP with tie bar has 0.5 mm lead pitch (per distributor Utmel listing) and requires careful solder-paste stencil design to prevent bridging on the fine-pitch perimeter leads. The tie bar must be soldered or mechanically anchored - leaving it floating creates a resonance point under vibration. Provide symmetrical fan-out around the package to minimize skew on wide parallel buses, and route the 5 V I/O bank with adequate spacing from the 3.3 V core domain to respect mixed-voltage creepage expectations.
