A54SX32A-1TQG100 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic by programming an array of configurable logic blocks and interconnects. Within the programmable logic hierarchy, the device sits as FPGA -> programmable logic IC -> logic IC -> embedded IC. The SX-A family uses a 0.25 um antifuse technology, which is one-time programmable: once configured, the interconnect is permanently set, providing inherent resistance to readback attacks and high reliability without a configuration boot sequence.
Key features include the -1 speed grade with up to 278 MHz system performance, 2.5V core operation for reduced power versus 3.3V-only devices, sea-of-modules architecture for efficient gate utilization, and 81 user-available I/O in the 100-pin TQFP. Because the antifuse fabric requires no external configuration memory, the part eliminates configuration PROMs from the bill of materials and starts instantly at power-up, which simplifies system design and improves security in applications where bitstream confidentiality matters.
Technically, the SX-A architecture organizes 2880 logic modules (Register Cells and Combinatorial Cells) into a routing fabric characterized by segmented antifuse interconnect, delivering deterministic, low-jitter routing delays suitable for state machines, bus interfaces, and glue-logic consolidation. The CMOS 0.25 um process balances performance, density, and low static power consumption.
Typical applications include industrial control and automation glue logic, communications line-card interface bridging, aerospace and defense secure logic (leveraging antifuse confidentiality), and cost-sensitive single-chip integration of multiple discrete logic devices in legacy or long-lifecycle systems.
When designing with this device, plan the one-time-programmable workflow carefully: verify the design fully in simulation and reserve spare I/O for future PLD requirements, since antifuse parts cannot be reprogrammed in-circuit.

主な用途
A54SX32A-1TQG100 の用途: 6 件s: Industrial Control and Automation Glue Logic, Secure Logic for Aerospace and Defense, Communications Line-Card Interface Bridging, Legacy System Obsolescence Redesign, Instant-On Power Sequencing and Supervision Logic, Test and Measurement Instrument Logic.
Industrial Control and Automation Glue Logic
In industrial controllers and PLC I/O cards, the A54SX32A-1TQG100 consolidates address decoders, bus transceivers, interrupt controllers, and state machines that once required dozens of 74-series devices. Its 48,000 system gates and 2880 logic modules absorb this glue logic into one chip, while the 81 user I/O in the 100-pin TQFP connects directly to backplane buses and peripheral connectors. The antifuse fabric starts instantly at power-up, so control logic is valid before microcontroller boot completes. The deterministic routing delays also simplify timing analysis for interlock and safety-adjacent logic. The commercial 0C to +70C grade suits enclosed factory equipment; use the A54SX32A-1TQG100I variant for uncontrolled-temperature cabinets.
おすすめ
Secure Logic for Aerospace and Defense
Antifuse FPGAs are a standard choice in defense and aerospace secure designs because the programmed interconnect cannot be read back, leaving no bitstream to steal or corrupt. The A54SX32A-1TQG100's 0.25 um antifuse fabric provides this confidentiality along with immunity to configuration upsets that plague SRAM FPGAs in radiation environments. With 32,000 typical gates and 278 MHz capability, it implements encryption interfaces, bus protocol bridges, and mission logic in a compact 100-pin TQFP. Designers should select the industrial or automotive temperature variants for wider environmental coverage and complete full simulation before programming, since the device is one-time programmable and cannot be reworked in the field.
おすすめ
Communications Line-Card Interface Bridging
Telecom line cards and network interface boards use the A54SX32A-1TQG100 to bridge processor buses to framing devices, serial links, and backplane interfaces. The -1 speed grade sustains up to 278 MHz toggle rates, comfortably handling common protocol clocks, while the sea-of-modules architecture provides efficient gate utilization for multi-protocol support in one 48,000-gate fabric. Its 2.5V core lowers static power versus 3.3V-only legacy PLDs, important in high-card-count shelves. Because there is no configuration PROM, a repowered shelf brings all interface logic up within microseconds, reducing reset sequencing complexity. The 0.5 mm-pitch TQFP-100 fits standard telecom card footprints with straightforward two-layer breakout.
おすすめ
Legacy System Obsolescence Redesign
When a discontinued ASIC, PLD, or bushel of TTL logic must be replaced in a long-lifecycle system, the A54SX32A-1TQG100 provides a low-cost single-chip integration target in the same 100-pin TQFP footprint as many legacy Actel devices, enabling PCB reuse without respin. Microchip keeps the SX-A family in production specifically to support such continuation designs. The 32,000 typical gates absorb counter chains, decoders, and sequencers, while the antifuse programming mirrors the permanently-configured behavior of masked ASICs. Designers migrating from older SX or SX-A parts in TQ100 packages can often drop in this SKU with only programming-file changes, preserving qualification evidence.
おすすめ
Instant-On Power Sequencing and Supervision Logic
Systems that need valid control logic within microseconds of power application - such as power-supply sequencing trees, watchdog supervision, and hot-swap controllers - benefit from the A54SX32A-1TQG100's antifuse instant-on nature: no configuration device, no boot delay, and no risk of a corrupted bitstream leaving rails undefined. The 2880 logic modules implement multi-rail sequencers with fault latching, and the 81 I/O drive enable and reset signals across the board. Its 2.5V core keeps quiescent draw low in always-on standby paths. Pair with voltage supervisors and ensure decoupling on the core rail; the design notes on this page cover decoupling and I/O bank guidance.
おすすめ
Test and Measurement Instrument Logic
Bench instruments and automated test fixtures use the A54SX32A-1TQG100 for timing generators, event counters, and pattern engines where deterministic, fixed routing delays matter for measurement repeatability. Once programmed, the antifuse interconnect contributes constant propagation delay - a property SRAM FPGAs cannot guarantee run-to-run after reconfiguration. The 278 MHz -1 speed grade supports common counter and trigger clocks, and the 100-pin TQFP's 81 I/O connect to front-panel connectors and probe buffers. Because the programming is permanent, calibration constants should be stored in external memory rather than the FPGA fabric. Full simulation prior to programming is essential since there is no in-circuit rework path.

設計ノート
The SX-A core operates from 2.5V. Power the core rail from a low-noise LDO or buck regulator with at least 10 uF bulk plus 0.1 uF ceramic decoupling per supply pin group. Estimated power dissipation is dominated by dynamic switching (f * C * V^2 per node), so at the 278 MHz ceiling with high toggle activity verify your supply budget with Microchip Designer's power estimation report rather than assuming worst-case static figures. Keep the I/O bank supply separate from the core rail to prevent simultaneous-switching noise from coupling into timing-critical internal nets.
This is a one-time-programmable antifuse device: it cannot be erased, reprogrammed, or reworked. Complete full RTL simulation, static timing analysis, and design review before submitting the design to programming, and program one verification unit before committing the full production quantity. Do not treat the 278 MHz figure as an achievable system clock for your design - it is the family architecture maximum; your actual fmax comes from Microchip Designer's timing report. Reserve spare I/O in your pin plan for late ECOs, since pin reassignment after programming is impossible.
The TQFP-100 lead pitch is 0.5 mm with a 1.4 mm package height. Use 0.2 mm-wide traces with solder-mask-defined pads for reliable reflow, and keep the fan-out escape region under the package to at least two signal layers plus dedicated ground plane. Place 0.1 uF ceramics within 2 mm of each supply pin pair. Because this is a legacy Actel-origin part frequently assembled alongside 3.3V and 5V-tolerant-adjacent logic, verify I/O voltage compatibility of every connected device against the SX-A I/O characteristics in the manufacturer datasheet.
The antifuse routing fabric delivers deterministic, fixed delays once programmed, which simplifies signal-integrity analysis of internal paths; however, board-level I/O edges remain CMOS push-pull. Series-terminate long lines (estimated 22-33 ohm resistors for 50-ohm traces) on clocks leaving the FPGA, and group related I/O on adjacent pins to minimize ground bounce across the package's ground returns. For multi-board systems, define reset and startup timing assuming logic is valid essentially instantly at power-up - no configuration boot delay exists.
