A54SX16-1VQG100 概要
An antifuse FPGA is a field-programmable gate array whose interconnect elements are open circuits that are permanently programmed to become low-resistance connections. Unlike SRAM-based FPGAs from Xilinx or Altera, an antifuse device is one-time programmable: its configuration is non-volatile, immune to configuration readback attacks, requires no external configuration PROM, and starts functioning within microseconds of power-up. Within the power management hierarchy of programmable logic, the SX family sits as a high-speed, low-power, secure fabric option for fixed-function designs.
Key features include a sea-of-modules architecture that yields deterministic sub-nanosecond routing delays, 0.35 um CMOS antifuse technology for low static power, and dual-voltage 3.3 V/5 V I/O operation enabling direct interfacing with legacy 5 V TTL systems. The 280 MHz toggle capability supports performance-intensive glueless integration of high-speed state machines and datapaths.
Technically, the SX architecture replaces the segment-and-switchbox routing of SRAM FPGAs with a sea-of-modules structure, so interconnect delay scales predictably with fanout rather than with routing congestion. The A54SX16 provides 16,000 equivalent gates (nominal 24,000 gates on some grades per Microsemi USA listings) implemented in configurable logic modules, supporting counter, arithmetic, and control functions at speeds unattainable by earlier Actel families.
Typical applications include industrial control and automation, aerospace and defense logic replacement, 5 V legacy bus interfacing, telecommunications line cards, and single-chip ASIC prototyping where non-volatile instant-on operation is mandatory.
Design consideration: antifuse programming is permanent, so verify the design fully in simulation and, ideally, on an SX-A debug device before programming production parts; also plan the 3.3 V core and 5 V I/O rail sequencing on the PCB.

主な用途
A54SX16-1VQG100 の用途: 6 件s: Industrial Control and Automation, Aerospace and Defense Logic Replacement, Legacy 5V Bus Interface Bridging, Telecommunications Line Cards, ASIC Prototyping and Glueless Integration, Secure Embedded Control.
Industrial Control and Automation
The A54SX16-1VQG100 fits industrial controllers because its 16,000 antifuse gates and 81 user I/O integrate counters, sequencers, and bus-interface logic that would otherwise need several 5 V TTL devices. Its sea-of-modules architecture sustains deterministic timing at up to 280 MHz, so state machines behave identically part-to-part without software configuration risk. In a PLC I/O card, the device sits between the backplane and isolation circuitry, with its 4.75 V to 5.25 V I/O rail connecting directly to legacy 5 V signals while the 3.0 V to 3.6 V core keeps dynamic power low. Because the configuration is non-volatile antifuse, the card is functional within microseconds of power-up and cannot be corrupted by noise or radiation-induced configuration upset, a tangible reliability benefit over SRAM FPGAs in electrically harsh factory environments.
おすすめ
Aerospace and Defense Logic Replacement
Defense and avionics sustaining programs favor the A54SX16-1VQG100 because antifuse configuration cannot be read back, providing inherent design security, and it tolerates power interruptions without losing its function. Replacing obsolete ASIC or SSI/MSI glue logic with one 16,000-gate device reduces board area, component count, and assembly cost while preserving a proven 5 V I/O interface to legacy backplanes. The -1 speed grade timing models in the Microchip 54SX datasheet support formal worst-case timing analysis required by qualification paperwork. Designers should complete full gate-level simulation before programming, since antifuse programming is permanent; a common flow is to validate on an SX-A device first, then commit the production A54SX16-1VQG100. The industrial-temperature A54SX16-VQG100I variant covers extended environmental ranges in the same footprint.
おすすめ
Legacy 5V Bus Interface Bridging
Many installed systems still run 5 V TTL or 5 V CMOS backplanes, and most modern logic cannot survive 5 V signaling. The A54SX16-1VQG100 solves this directly: its I/O ring is powered from 4.75 V to 5.25 V while the core runs at 3.0 V to 3.6 V, so 81 I/O can drive and receive 5 V-level signals without level translators. Typical roles include VME/ISA-style bus monitoring, address decoding, and handshake generation, where the 280 MHz-class fabric easily exceeds bus timing requirements. Because the part is non-volatile, the bridge is active at power-on before a host completes initialization, which matters for systems that sample bus state during boot. Decouple both rails separately and verify absolute maximum ratings on the 5 V rail during transients per the datasheet.
おすすめ
Telecommunications Line Cards
Telecom line cards use the A54SX16-1VQG100 for framing, counting, alarm scanning, and control-plane glue logic between physical-layer devices and the card controller. The 16,000-gate capacity accommodates multiple T1/E1-style support functions, and the -1 speed grade's deterministic routing means timing sign-off done once remains valid across production lots. The antifuse fabric draws low static power, which reduces the per-card power budget in high-density shelves, and the non-volatile configuration removes the cost and failure points of boot PROMs, a meaningful MTBF improvement across thousands of cards. Designers typically pair the FPGA with precision converters such as the ADS1220IPWR for supervision channels. For new designs, evaluate the pin-compatible SX16P generation (A54SX16P-1VQG100I) for improved speed and power in the identical footprint.
おすすめ
ASIC Prototyping and Glueless Integration
Before committing to an ASIC mask set, engineers use the A54SX16-1VQG100 to validate control logic and datapath blocks in-system at realistic speeds. The 280 MHz-capable sea-of-modules fabric outpaces typical SRAM FPGAs of the same era for simple, regular logic, and the 16,000-gate capacity suits address decoders, FIFO controllers, and protocol state machines. Because the antifuse part is permanently programmed, prototype iterations require new devices; teams commonly debug on pin-compatible SX-A or SX16P devices and reserve programmed A54SX16-1VQG100 parts for customer demonstrations and pilot builds. The 100-pin TQFP with 0.5 mm pitch is hand-solderable for lab bring-up, and 81 I/O give ample probe and expansion access. This makes the device a low-risk stepping stone between simulation and silicon.
おすすめ
Secure Embedded Control
Applications that must resist cloning benefit from the A54SX16-1VQG100's one-time-programmable antifuse fabric: unlike SRAM FPGAs, there is no bitstream to intercept at boot and no configuration memory to read back, so proprietary algorithms loaded into the 16,000 gates are effectively physically protected. Typical secure-control roles include authentication of sensor modules, license-key logic, and anti-tamper sequencers in commercial and government equipment. The instant-on characteristic means security logic is active within microseconds of power application, closing the boot window that bitstream-loading architectures expose. The industrial-temperature A54SX16-VQG100I in the same 100-TQFP footprint supports harsh deployments. Combine with a secure authentication IC or crypto element on the I/O side for layered protection; XAIPART stocks companion ISOCOM/ISO devices for isolated interfaces.

設計ノート
The A54SX16-1VQG100 requires two rails: 3.3 V nominal core (3.0-3.6 V) and 5.0 V nominal I/O (4.75-5.25 V). Power the core from a precision LDO or buck converter and never swap the rails; applying 5 V to the core pins damages the device permanently. Decouple each rail with at least 10 uF bulk plus 0.1 uF ceramic per supply pin group. Because antifuse fabric draws low static current, the core rail is usually the smaller load; verify total dynamic current with Microsemi Designer power estimation before sizing regulators.
Antifuse devices are one-time programmable: a single incorrect fuse file permanently destroys the unit. Always complete post-layout timing simulation and, where possible, validate on an SX-A or SX16P device before programming the production A54SX16-1VQG100. Confirm the speed-grade compiler setting matches -1; compiling for -2 and programming a -1 part produces a design that violates its own timing. Keep revision-controlled fuse files mapped to board serial numbers to avoid mis-programming in production.
The 100-TQFP footprint uses 0.5 mm lead pitch with a 14x14 mm body; specify the land pattern per the JESD-30 S-PQFP-G100 outline and use a no-clean or water-wash solder process with stencil apertures sized to prevent bridging on the fine pitch. Route the unused 81-I/O budget as inputs with board-level pull-downs or configure as defined in your design to avoid floating nodes. Keep 5 V I/O traces separated from sensitive analog routing, and place series termination on long 5 V bus lines to control ringing.
