A54SX32-BG313I Descripción general
An antifuse FPGA is a type of field-programmable gate array whose interconnect switches are permanently programmed at power-up programming time, in contrast to SRAM-based FPGAs that load configuration data from external memory at every boot. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), antifuse devices are valued for instant-on behavior, non-volatile configuration, low power, and high resistance to configuration error or radiation-induced upset.
Key features include the SX sea-of-modules architecture that shortens design time and reduces power, dual supply ranges (3V~3.6V core and 4.75V~5.25V per listed specification data), and a dense 35x35 mm 313-PBGA footprint delivering 249 I/O for wide-bus designs. The -I suffix denotes industrial temperature operation.
Architecturally, the SX family's sea-of-modules fabric provides predictable routing and high effective gate utilization, supporting performance-intensive applications where SRAM FPGA reconfiguration is unnecessary.
Typical applications include industrial control, communications and networking line cards, aerospace and defense logic glue, and test equipment, where non-volatile, instant-on logic is required.
Design consideration: because antifuse programming is one-time, complete functional simulation and pin-planning verification before programming are essential; there is no field rework path.

Aplicaciones típicas
A54SX32-BG313I es adecuado para 6 aplicacións: Industrial Control Systems, Communications and Networking Line Cards, Aerospace and Defense Logic, Test and Measurement Equipment, Medical Device Control Logic, Battery-Powered and Low-Power Systems.
Industrial Control Systems
The A54SX32-BG313I fits industrial control and factory automation logic where non-volatile, instant-on FPGA configuration eliminates boot-time configuration loading from external memory. Its 32,000 gates and 2880 configurable logic blocks handle glue logic, bus interfacing, sequencing, and I/O expansion across up to 249 user I/O, sufficient for wide parallel backplanes and motor-control interface logic. The industrial temperature grade (-I) supports harsh plant-floor environments, and the 3.0V to 3.6V supply range matches standard 3.3V industrial rails. Because antifuse programming is permanent, designers should fully validate control logic in simulation before programming, since there is no field-update path on this legacy EOL device.
Recomendado
Communications and Networking Line Cards
In communications and networking equipment, the A54SX32-BG313I provides line-card glue logic, backplane bus bridging, and framing support at clock rates up to 240 MHz, which was state-of-the-art for antifuse FPGA fabrics in its generation. The SX sea-of-modules architecture delivers predictable routing delay, important for timing-critical data-path functions, while 249 user I/O support wide parallel data buses typical of telecom backplanes. The non-volatile antifuse configuration means the line card is functional the instant power is applied - an advantage over SRAM FPGAs that need bitstream loading. The EOL status means new telecom designs should treat this part as a legacy-sustainment component only.
Recomendado
Aerospace and Defense Logic
The SX antifuse family, including the A54SX32-BG313I, was widely adopted in aerospace and defense systems because antifuse configuration is inherently resistant to configuration upset and requires no external configuration storage that could be corrupted. The 32,000-gate capacity implements mission logic, protocol handlers, and sensor-interface functions with up to 249 I/O. The -M package sibling (A54SX32-BG313M) provides a military temperature-grade drop-in within the same 313-BBGA footprint, enabling temperature-tier sourcing on a single board layout. Designers must note the one-time-programmable nature: flight logic must be fully verified before programming, and RoHS non-compliance is generally acceptable under defense exemptions.
Recomendado
Test and Measurement Equipment
Test and measurement instruments benefit from the A54SX32-BG313I's instant-on behavior and deterministic timing, both direct consequences of antifuse configuration and the SX sea-of-modules routing fabric. With clock support to 240 MHz and 249 user I/O, it suits trigger logic, counter/timer front ends, pattern generators, and instrument bus interfaces. The industrial temperature rating supports bench and field instruments alike, and the 35x35 mm 313-BBGA provides dense I/O without the configuration-loading delay of SRAM devices. Since the part is EOL and one-time programmable, instrument manufacturers sustaining existing products should secure lifetime-buy inventory while broker stock such as the 5109 listed pieces remains available.
Recomendado
Medical Device Control Logic
Medical diagnostic and monitoring equipment can use the A54SX32-BG313I for deterministic control logic, sensor-timing generation, and interface bridging where instant-on operation matters: the device is fully functional immediately at power-up with no configuration fetch. The 32,000-gate capacity with 2880 CLBs covers control sequencing and data-path glue logic, while 249 I/O support multi-channel sensor boards. The industrial temperature range comfortably exceeds typical medical operating environments. Designers must account for the RoHS non-compliant, leaded-BGA construction when evaluating regulatory compliance for new medical products, and should verify long-term supply given the EOL status before designing this part into new hardware.
Recomendado
Battery-Powered and Low-Power Systems
The SX family's CMOS antifuse architecture consumes no static configuration power for bitstream storage, and Microchip's SX marketing specifically cites dramatic reductions in power consumption versus comparable SRAM FPGA solutions of its era. This makes the A54SX32-BG313I suitable for battery-backed and power-conscious systems needing 32,000 gates of always-ready logic with 249 I/O and 3.0V to 3.6V operation from a standard 3.3V rail. Instant-on behavior eliminates the power spike of configuration loading. Engineers should quantify quiescent and dynamic current for their specific design using the SX datasheet power calculator, and should treat this EOL part as a sustainment choice for existing low-power platforms rather than new designs.

Notas de diseño
The A54SX32-BG313I is a one-time-programmable antifuse FPGA. There is no field rework path: once programmed, the configuration is permanent. Complete functional simulation, timing closure, and pin assignment verification in the Actel/Microsemi Designer toolchain BEFORE programming the device. Per the SX family datasheet, programming burns the antifuse interconnect permanently, so a design bug after programming means scrapping the packaged device.
Supply the core from a regulated 3.3V rail (3.0V to 3.6V range). The specification data also lists a 4.75V to 5.25V range on this device family, so verify which supply rail maps to which balls in your design per the SX datasheet pin tables before layout. Decouple with low-ESR ceramics placed close to the BGA power balls. Estimated: at 240 MHz with high toggle rates, dynamic current scales with switching activity, so use the Microchip SX power estimation spreadsheet rather than worst-case numbers for sizing the regulator.
The 313-BBGA is a 35x35 mm, 1.27 mm-pitch ball grid array requiring a dedicated footprint and via-in-pad or dog-bone escape routing on the PCB. Plan at least four signal layers plus power/ground planes for 249 user I/O breakout. Because this part is EOL and non-RoHS (contains lead), confirm your assembly house accepts leaded BGA reflow profiles, and consider that board redesigns targeting RoHS-compliant alternatives will require a completely new footprint.
