A54SX32A-TQG144IX53 概要
An antifuse FPGA is a field-programmable gate array whose interconnect switches are one-time-programmable antifuse elements rather than SRAM configuration cells. Within the programmable logic hierarchy (FPGA -> programmable logic device -> programmable semiconductor), antifuse devices are nonvolatile at power-up, immune to configuration readback, and exhibit very low routing capacitance, which yields the high speed and low power the SX-A family is known for.
Key features include a sea-of-modules architecture built from C-cell (combinatorial) and R-cell (register) modules, 2880 configurable logic modules per Microchip USA listing, 113 user I/O on the 144-TQFP package, and flexible 2.5 V, 3.3 V, and 5 V I/O operation. Fast pin-to-pin timing of 3.7 ns clock-to-out, 0.1 ns input setup, and 0.25 ns clock skew supports 66 MHz PCI-class designs, with 100% resource utilization and 100% pin locking.
The SX-A architecture covers the entire die with a grid of logic modules, so virtually no chip area is lost to interconnect - a major reason the family achieves high gate utilization and predictable timing. Fabricated on 0.22 um / 0.25 um CMOS antifuse process technology, the device is single-chip, low-power, and secure against design extraction, making it attractive for cost- and security-sensitive integration.
Typical applications include industrial control and automation logic, communications and networking glue logic, aerospace and defense systems that need power-up nonvolatile and configuration-security, and PCI bridge or bus-interface designs.
Design consideration: antifuse devices are one-time programmable - verify your netlist thoroughly in simulation before programming, and select the correct speed grade (IX53 = industrial temperature) since rework after programming is impossible.

主な用途
A54SX32A-TQG144IX53 の用途: 6 件s: Industrial Control and Automation Logic, PCI Bus Interface and Bridge Logic, Aerospace and Defense Secure Logic, Communications and Networking Equipment, Test and Measurement Instrumentation, Legacy 5V System Migration and BOM Rescue.
Industrial Control and Automation Logic
The A54SX32A-TQG144IX53 fits industrial control and factory automation designs that need high gate utilization, deterministic timing, and power-up nonvolatile operation. Its 32K system gates and 2880 configurable logic modules integrate sequencer, state-machine, and glue-logic functions that would otherwise require several CPLDs, cutting board area and BOM cost. The 3.7 ns pin-to-pin clock-to-out and 0.25 ns clock skew support synchronous backplane interfaces, while 5 V-tolerant I/O modes connect directly to legacy 5 V PLC signaling. Because the antifuse fabric retains its configuration through power cycles and brownouts, no external configuration flash is needed - a reliability advantage in electrically noisy factory environments.
おすすめ
PCI Bus Interface and Bridge Logic
The SX-A family datasheet explicitly positions the A54SX32A for 66 MHz PCI CPLD and FPGA integration as a single-chip solution. With 0.1 ns input setup, 0.25 ns clock skew, and 3.7 ns clock-to-out, the device closes PCI timing at 66 MHz while achieving 100% resource utilization with 100% pin locking - critical when a fixed PCB layout must survive logic updates. The 32K-gate density accommodates a complete PCI target or compact master/bridge function, and the 113 user I/O cover the full 32/64-bit PCI signal group plus local-side logic. Antifuse interconnect's low capacitance also lowers dynamic I/O power, useful in multi-slot PCI systems.
おすすめ
Aerospace and Defense Secure Logic
Antifuse FPGAs are preferred in aerospace and defense payloads because the one-time-programmable fabric contains no bitstream that can be read out or corrupted by SEU-induced configuration upsets in the way SRAM FPGAs can. The A54SX32A-TQG144IX53's industrial ordering code suits ruggedized ground and airborne-support equipment, while other SX-A ordering codes (e.g., M suffix bins) address extended-temperature programs. The 48,000-gate module organization and 1800 cells absorb command decoders, telemetry formatters, and bus glue logic in a single 144-TQFP, reducing component count on high-reliability boards. Low static power of the antifuse fabric also helps in power-constrained platforms.
おすすめ
Communications and Networking Equipment
Networking line cards and backplane controllers benefit from the SX-A's high internal speed (238 MHz) and fast pin-to-pin timing for framing, multiplexing, and bus-translation logic. The A54SX32A-TQG144IX53 integrates address decoding, interrupt control, and PHY-side glue logic that would otherwise occupy multiple discrete devices, delivering the family's promised system-wide cost savings from single-chip integration. Its 3.3 V and 2.5 V I/O compatibility matches modern PHY and MAC voltages, while 5 V-tolerant modes bridge legacy telco interface boards. The configuration-security of antifuse technology also protects proprietary protocol logic from extraction in field-deployed telecom hardware.
おすすめ
Test and Measurement Instrumentation
Bench instruments and ATE modules use the A54SX32A-TQG144IX53 as a timing-controller and trigger-logic engine. The 0.25 ns clock skew across the fabric keeps parallel sampling strobes aligned, and the 3.7 ns clock-to-out supports rapid stimulus handshaking. With 2880 logic modules, a single device replaces the pattern-generator counters, edge decoders, and interface state machines typically spread across several SPLDs, improving timing predictability. The industrial temperature range and nonvolatile antifuse configuration allow the same board to ship into both lab and factory-floor instrument variants without configuration storage or boot sequencing, simplifying calibration and reducing startup latency to zero.
おすすめ
Legacy 5V System Migration and BOM Rescue
Many service programs still run 5 V buses that modern SRAM FPGAs cannot directly join. The A54SX32A-TQG144IX53 accepts 5 V I/O operation alongside 3.3 V and 2.5 V, letting engineers consolidate obsolete PAL/GAL/22V10 and EPLD clusters into one antifuse FPGA without level-shifting silicon. This is a common BOM-rescue strategy when original programmable parts go end-of-life: the 144-TQFP footprint and 113 user I/O absorb multiple legacy pinouts, and pin locking keeps the existing PCB unchanged. Because the fabric is one-time-programmable and nonvolatile, replacement boards behave identically to the original assemblies from the first power cycle.

設計ノート
Antifuse devices are one-time programmable. Never power the programmer with a marginal 2.5 V core supply, and always run full post-layout timing simulation in Libero Designer before generating the fuse file. A programming error or netlist bug permanently consumes the device - there is no erase/reprogram cycle as with SRAM FPGAs. Keep at least one programmed spare per production batch, and version-control your fuse files alongside the PCB revision so field service can match boards to the correct programming data.
Decouple the 2.5 V core and each I/O bank with 0.1 uF ceramics at the TQFP corners plus one 10 uF bulk capacitor per rail. The antifuse fabric draws low static current, but dynamic I/O power dominates when driving 5 V-tolerant loads at high toggle rates - estimate per-bank current from your Libero power report, not from the family datasheet typicals. Ensure the 5 V I/O mode is only selected on banks whose trace topology and clamp requirements match your legacy interface, since mixed-voltage bank assignment is fixed at programming time.
The 144-pin TQFP has 0.5 mm-pitch leads; use a 4-mil trace/6-mil space escape fan-out and tie the exposed corner lead pattern per the SX-A datasheet package drawing. For 66 MHz PCI designs, keep trace lengths under the datasheet's PCI loading guidance and add series termination on clock outputs to control reflections from the 0.25 ns clock-skew budget. Avoid routing under the package body on outer layers to reduce crosstalk into the dense lead field.
