A54SX16-1VQG100I 概要
An antifuse FPGA is a one-time-programmable field-programmable gate array in which each interconnect is an open circuit until permanently programmed by a high-voltage pulse. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), antifuse devices such as the SX family contrast with SRAM-based FPGAs: they retain configuration through power cycles without an external configuration PROM, exhibit very low static power, and offer intrinsically higher resistance to configuration corruption, which historically made them popular in military, aerospace, and industrial systems.
Key features of the A54SX16-1VQG100I include the 0.35 um SX sea-of-modules architecture, dual 3.3V/5V supply operation that eases mixed-voltage board integration, industrial-grade -40C to +85C temperature qualification (indicated by the I suffix), and 280 MHz toggle capability for performance-intensive glue logic, bus interfacing, and state machine integration.
Technically, the SX family uses a sea-of-modules architecture built around a compact logic module that simplifies routing while keeping interconnect delays short and predictable. The '1' speed grade balances cost and performance, and the antifuse fabric yields low net capacitance, supporting both high speed and low power consumption in a single-chip solution that can integrate multiple SSI/MSI devices.
Typical applications include legacy industrial control and automation boards, 5V-tolerant bus interface and glue logic consolidation, telecommunications line cards, and obsolescence-management redesigns where a one-time-programmable, non-volatile FPGA is required.
Design consideration: because antifuse programming is irreversible, complete design sign-off, timing closure, and programming-fixture verification must precede device programming; a programming error renders the device unusable.

主な用途
A54SX16-1VQG100I の用途: 6 件s: Industrial Control and Automation, Legacy 5V Bus Interface and Glue Logic Consolidation, Telecommunications Line Cards, Obsolescence Management and Last-Time-Buy Redesigns, Aerospace and Defense Ground Equipment, Test and Measurement Instrumentation.
Industrial Control and Automation
The A54SX16-1VQG100I fits industrial control boards because its industrial -40C to +85C rating and 24,000 usable gates cover PLC I/O grooming, encoder interfacing, and interlock state machines in a single chip. Its 81 user I/O pins consolidate dozens of 74-series glue devices, cutting board area and assembly cost, while the 3V-3.6V and 4.75V-5.25V dual supply range connects directly to both 5V field-side logic and 3.3V controller domains. Because the antifuse fabric is one-time programmable and non-volatile, the design powers up instantly with no configuration device - an advantage on machinery that must not wait for bitstream loading. The speed-grade-1 timing at up to 280 MHz far exceeds typical industrial sequencing needs, giving large timing margin over long, lightly loaded nets.
おすすめ
Legacy 5V Bus Interface and Glue Logic Consolidation
For boards that still run 5V TTL backplanes, the A54SX16-1VQG100I is a natural fit: its 4.75V-5.25V supply rail allows direct 5V-domain operation, and the 81 I/O absorb address latching, chip-select decoding, and byte-swap functions that previously consumed multiple SSI/MSI packages. The 0.35 um SX architecture keeps interconnect delay short and predictable, so decoded strobes meet legacy setup times at 280 MHz-class internal toggle rates. Consolidating into one antifuse FPGA also removes configuration PROMs from the BOM because programming is permanent and survives every power cycle. Designers should reserve the VPP programming pins on the 100-pin TQFP footprint in layout so that in-system programming fixtures can access them during production.
おすすめ
Telecommunications Line Cards
Telecom line cards benefit from the A54SX16-1VQG100I's combination of 924 logic cells, 81 I/O, and fast, deterministic routing for framing, alarms, and backplane handshaking. The 280 MHz internal capability comfortably covers E1/T1-class supervisory logic, and the antifuse fabric's low static power suits cards populated by the dozens in shelves with constrained airflow. The industrial -40C to +85C rating covers uncontrolled outdoor plant equipment, while the 14x14 mm 100-TQFP package simplifies rework compared with BGA alternatives. Because the device is one-time programmable, feature freezes must precede production programming; for platforms with evolving firmware-like requirements, evaluate SRAM-based fabrics instead of forcing repeated respins of antifuse parts.
おすすめ
Obsolescence Management and Last-Time-Buy Redesigns
The A54SX16-1VQG100I plays a central role in obsolescence programs: it replaces discontinued PAL/GAL/EPLD clusters and custom glue ASICs on long-lifecycle boards such as railway, energy, and military ground equipment. Since the SX16 die shares the 100-pin VQFP footprint with A54SX08 and SX-A family siblings, a single PCB land pattern can absorb several density and speed-grade variants, decoupling board design from part availability. The non-volatile antifuse fabric eliminates configuration storage, a frequent reliability concern in stored spares. Recommended practice is to qualify at least two pin-related orderable variants (for example the 1 and 2 speed grades or the P-variant packages) so procurement can pivot when one suffix goes on allocation.
おすすめ
Aerospace and Defense Ground Equipment
Antifuse FPGAs are historically favored in defense applications because their programmed interconnects are immune to configuration upsets and cannot be read back or overwritten, supporting design-protection goals. The A54SX16-1VQG100I serves ground-based radar control panels, test-set interface boards, and secure communications adjuncts that operate within the -40C to +85C industrial envelope; for wider-temperature or screened programs, the A54SX16P-1VQG100M M-suffix variant of the same die and package provides military-grade processing. With 24,000 gates and 81 I/O, typical functions include bus arbitration, peripheral handshaking, and watchdog logic. Designers must lock the netlist and timing report at tape-out because antifuse programming is irreversible and field updates are impossible.
おすすめ
Test and Measurement Instrumentation
Bench instruments and rack testers use the A54SX16-1VQG100I as deterministic trigger, timing-strobe, and backplane-interface logic. Its 280 MHz capability and short, predictable antifuse routing deliver repeatable channel-to-channel skew, which matters for go/no-go test gating, while 81 I/O address relay matrices and per-slot status lines on the 100-TQFP footprint. The non-volatile configuration removes boot-time delays in instruments expected to be ready at power-on, and dual 3.3V/5V rails bridge legacy GPIB-style 5V circuitry with modern 3.3V microcontroller domains. For new instrument platforms, designers often prototype on SRAM-based FPGAs, then port the frozen netlist to this antifuse part for the production revision.

設計ノート
The A54SX16-1VQG100I is one-time programmable: once the antifuse array is blown, the device cannot be erased, verified in-system, or reused. Complete functional simulation, static timing closure at speed grade 1, and programming-file review before releasing devices to the programmer. Hold 5-10% spare unprogrammed devices per build to absorb programming-yield loss, since a single VPP misapplication destroys the part.
Decouple the 3.3V (3V-3.6V) and 5V (4.75V-5.25V) domains independently: place 0.1 uF ceramic capacitors at each VCC pin pair of the 100-TQFP plus at least one 10 uF bulk capacitor per rail. Because the antifuse fabric has no configuration current at power-up, inrush is dominated by I/O loading - size the 5V rail regulator for simultaneous switching of up to 81 outputs, and keep VPP programming pins per the SX family programming specification during normal operation.
Use the 14x14 mm 100-TQFP land pattern from the SX family package drawing with standard 0.5 mm pitch footprints; keep trace stubs under 10 mm on decoded strobes to preserve the speed-grade-1 timing margin, and dedicate a solid ground plane under the device. Reserve probe pads on the programming-related pins so production fixtures can program devices after reflow per the manufacturer's recommended flow.
