A54SX16P-VQ100 概要
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer wires together after manufacturing. Within the programmable logic hierarchy, the A54SX16P sits in the one-time-programmable antifuse FPGA class: FPGA -> antifuse FPGA -> programmable logic device (PLD) -> digital logic IC. Antifuse technology means the interconnect is permanently set at programming time, giving lower static power, higher immunity to configuration upset, and no external configuration memory requirement compared with SRAM FPGAs.
Key features of the A54SX16P-VQ100 include the sea-of-modules architecture of the Actel SX family, which simplifies design timing closure and reduces power consumption; the 240 MHz system performance suited to performance-intensive applications; the 81 I/O count with a fine-pitch 100-terminal thin quad flat pack; and the dual-rail supply scheme that eases integration into mixed 5V and 3.3V board environments.
Architecturally, the SX family uses a sea-of-modules fabric where each module is a compact combinational element combined with dedicated routing resources. This yields deterministic, short interconnect delays, which is why SX devices historically served high-speed glueless system integration, bus bridging, and state-machine logic where SRAM-FPGA configuration time and configuration-storage overhead were undesirable.
Typical applications include industrial control and automation logic, telecommunications and networking line-card glue logic, military and avionics system controllers (the military-grade M suffix variant exists), and legacy system life-cycle replacement where the original design must be maintained without PCB redesign.
When designing with the A54SX16P-VQ100, verify supply sequencing of the dual rails and confirm the antifuse programming flow (Silicon Sculptor programming hardware) before committing to volume; one-time-programmable devices do not allow in-system reconfiguration.

主な用途
A54SX16P-VQ100 の用途: 6 件s: Industrial Control and Automation Logic, Telecommunications Line-Card Glue Logic, Legacy System Life-Cycle Maintenance, Test and Measurement Instrumentation, Military and Aerospace Controllers, Mixed 5V/3.3V Board Integration.
Industrial Control and Automation Logic
The A54SX16P-VQ100 fits industrial control and factory automation systems that need deterministic, glueless logic between PLC processors, sensor arrays, and actuator drivers. Its 81 user I/O pins provide ample parallel interfaces for discrete and encoded signal integration, while the 240 MHz maximum clock frequency comfortably covers high-speed counter, PWM generation, and state-machine tasks. Because the SX antifuse fabric needs no configuration memory, the design powers up instantly and cannot be corrupted by industrial EMI or brownouts, a common failure mode of SRAM FPGAs in noisy motor-drive cabinets. Place the device on a 3.3V core rail with a 5V auxiliary rail to drive legacy 5V-logic peripherals directly, and provide local 0.1uF decoupling at each supply pin.
おすすめ
Telecommunications Line-Card Glue Logic
In telecom line cards and backplane interfaces, the A54SX16P-VQ100 serves as protocol adaptation and bus-bridging glue logic between physical-layer devices and the system controller. The sea-of-modules architecture delivers deterministic interconnect delays, which simplifies meeting fixed timing budgets on framed data paths such as E1/T1 framers and backplane parallel buses. With 16,000 system gates and 1,452 CLBs, the device absorbs address decoding, FIFO control, and interrupt aggregation that would otherwise require several PLDs. Its instant-on antifuse configuration is valuable in carrier equipment where systems must be operational within milliseconds of power application. Commercial 0C to +70C rating suits central-office ambient environments; select the I-grade variant for outside-plant cabinets.
おすすめ
Legacy System Life-Cycle Maintenance
The primary modern role of the A54SX16P-VQ100 is sustaining legacy systems originally designed around the Actel SX family, including avionics, military, and industrial platforms still in service for decades. Because the 100-pin VQFP footprint and pinout are shared across the A54SX16P package variants (VQG100, VQG100I, VQG100M, and -1/-2 speed grades), a failed or obsolete-graded device can be replaced drop-in without PCB rework, requiring only a Libero design recompile when changing speed grade. The one-time-programmable antifuse fabric preserves the original design intent with no firmware-update burden. XAIPART stocks multiple A54SX16P VQ100 variants, enabling last-time-buy consolidation and obsolescence bridging for long-service-life fleets.
おすすめ
Test and Measurement Instrumentation
Bench and rack instrumentation benefit from the A54SX16P-VQ100 as a deterministic timing and control element for trigger logic, counter/timer channels, and bus interfaces. The 240 MHz fabric speed supports sub-10 ns control-loop resolution, and antifuse determinism ensures the same routing delays on every manufactured unit, an advantage over SRAM FPGAs whose timing varies per bitstream placement. Its dual-rail operation (3.0-3.6V core, 4.75-5.25V auxiliary) eases integration into instruments that retain 5V TTL front ends. With 81 I/O, one device typically replaces several dozen 74-series glue chips, improving reliability and reducing board area in the measurement signal path. Designers should verify timing closure at the target clock frequency using static timing analysis before programming.
おすすめ
Military and Aerospace Controllers
The A54SX16P-VQ100M military variant demonstrates the SX family's role in defense electronics, where one-time-programmable antifuse FPGAs are favored for configuration-upset immunity and instant-on behavior. The A54SX16P-VQ100 commercial part serves ground-based military support equipment, test sets, and non-flight industrial-defense hybrids. Its 16,000 gates cover controller interfaces, Mil-Std bus bridging, and discrete I/O expansion, while the sealed, non-volatile fabric withstands vibration and radiation-heavy environments better than SRAM configurations that can flip during upset events. For high-reliability programs, specify the M-suffix screened device in the identical 100-TQFP footprint, preserving PCB layouts already qualified for the VQ100 package.
おすすめ
Mixed 5V/3.3V Board Integration
The A54SX16P-VQ100's dual supply requirement of 3.0-3.6V and 4.75-5.25V makes it particularly well suited to mixed-voltage boards bridging legacy 5V TTL subsystems with modern 3.3V processors. The device integrates bus translation, handshaking, and address decoding between voltage domains without external level-shift glue, since SX family I/O structures were designed for this dual-rail environment. Typical deployments include retrofit controllers where new 3.3V microcontroller boards must drive existing 5V relays, displays, or industrial sensor buses. The 81 I/O budget accommodates wide parallel buses up to 64 bits plus control strobes. Provide solid 0.1uF and 10uF decoupling on both rails and verify I/O bank voltage assignments in the datasheet before routing.

設計ノート
The A54SX16P-VQ100 requires two independent supply rails: 3.0-3.6V core and 4.75-5.25V auxiliary. Estimated: with a 5V auxiliary rail and typical SX quiescent plus I/O loading, budget each rail with at least 20% headroom over measured worst-case current from your Libero power estimate. Place 0.1uF ceramic decoupling at every supply pin pair and one bulk 10uF per rail. Do not share the 5V rail with high-switching-noise loads such as relays, since antifuse FPGAs tolerate brownouts but I/O ringing can corrupt fast parallel buses.
The SX family is one-time programmable: once antifuses are blown, the logic cannot be changed. Complete full functional simulation and static timing analysis at your maximum clock (up to 240 MHz device rating) before programming. Legacy Actel Activator 2/2S programmers are being phased out - use the Silicon Sculptor programming station per Actel/Microchip programming documentation. Also note the standard part is rated only 0C to +70C; selecting A54SX16P-VQ100I costs little and removes ambient-range risk in enclosures.
The 100-pin TQFP (14x14 mm, 0.5 mm pitch) requires fine-pitch soldering: use a 0.18-0.2 mm stencil with NSMD pads and verify with X-ray or AOI, as TQFP leads are prone to bridging at 0.5 mm pitch. Keep the unused corner thermal relief region per the datasheet land pattern. For mixed-voltage designs, route the 5V I/O traces with at least 0.3 mm spacing from 3.3V signals to maintain creepage and prevent crosstalk on the shared fine-pitch breakout region.
At clock rates approaching the 240 MHz device maximum, keep clock traces short and series-terminate (estimated: 22-33 ohm depending on trace impedance) to control ringing on the TQFP's relatively inductive leads. Because antifuse routing delays are deterministic, post-layout timing simulation reflects silicon exactly, so use it rather than generic worst-case derating. Avoid routing 5V-level outputs adjacent to sensitive analog inputs on the same bus to limit coupling through the package lead frame.
