Typical Applications

A54SX16P-2VQG100 is suitable for 6 applications: Industrial Control and Automation, Communications and Networking Interface Logic, Test and Measurement Instrumentation, Military and Aerospace Legacy System Sustainment, Embedded System Glue Logic and Bus Bridging, Battery-Powered and Portable Instrumentation.

🏭

Industrial Control and Automation

The A54SX16P-2VQG100 fits industrial PLC I/O, motor-control sequencing, and machine-state logic because its 16,000 gates and 1452 CLBs absorb substantial glue logic, counters, and state machines in one device, while its 0.7 ns combinatorial CLB delay keeps deterministic control paths fast. In use, the FPGA sits between backplane buses and I/O modules, implementing address decoding, handshaking, and PWM generation at up to 320 MHz internal toggle rates. Its antifuse configuration is immune to configuration upsets at power cycling, an advantage over SRAM FPGAs in factory equipment, and the 3.3V/5V supply support bridges legacy 5V industrial buses with modern 3.3V logic.

🌐

Communications and Networking Interface Logic

Telecom line cards and protocol bridges benefit from the A54SX16P-2VQG100's fast decode modules and predictable routing delays. The 320 MHz toggle capability and 0.7 ns CLB delay support framing, multiplexing, and interface-conversion logic for T1/E1, backplane, and embedded control paths. Because the SX architecture provides short, consistent interconnect delays, designers can close timing on multi-signal bus interfaces without extensive pipelining. The 3.3V core with 5V-tolerant I/O options lets the device directly connect to legacy 5V line-card circuitry, reducing level-shifting components. Non-volatile antifuse startup means the card is live immediately on power-up, simplifying hot-swap and redundant-card designs where a configuration loader would add boot latency.

πŸ”§

Test and Measurement Instrumentation

Bench and automated test equipment use the A54SX16P-2VQG100 for timing generation, event counting, trigger logic, and instrument bus interfacing. Its 924 logic cells and 320 MHz performance handle high-resolution counter/timer functions, while deterministic antifuse timing makes measured channel-to-channel skew repeatable across instruments. The device's non-volatile configuration means an instrument powers to a known operational state instantly, supporting rapid self-test routines. With 0.35um CMOS process power characteristics and a commercial 0C to +70C range, it suits rack-mounted equipment with controlled environments. Designers typically combine the FPGA with precision data converters to build custom acquisition sequencers and hardware compare engines.

✈️

Military and Aerospace Legacy System Sustainment

Many fielded military and aerospace platforms were designed around the Actel SX family, and the A54SX16P-2VQG100 is used to sustain those systems where requalification of a modern FPGA would be prohibitively costly. The antifuse technology is inherently radiation-tolerant-friendly and configuration-upset resistant compared to SRAM FPGAs, a key reason the architecture was adopted in avionics and ordnance controllers. Its instant-on non-volatile configuration suits safety-critical power-up sequencing, and the 16K-gate capacity matches the scale of original qualifying designs. The same 100-pin VQFP footprint is shared across the SX16P grade variants, enabling temperature-grade swaps without board redesign.

🧩

Embedded System Glue Logic and Bus Bridging

The A54SX16P-2VQG100 consolidates address decoders, bus transceivers, interrupt controllers, and wait-state generators that would otherwise occupy many 74-series devices. With 16,000 gates and 924 cells, one package replaces dozens of SSI/MSI chips, cutting board area, assembly cost, and failure points. The 0.7 ns combinatorial delay preserves the fast access timing that discrete glue logic provided, and 3.3V/5V operation lets it sit directly on legacy microprocessor buses. Because the antifuse device is one-time programmable, its logic is fixed at production - an advantage for configuration control in certified or long-lifecycle embedded products where SRAM FPGA bitstreams would require secure-boot provisions.

πŸ“±

Battery-Powered and Portable Instrumentation

The SX family's sea-of-modules architecture is explicitly positioned by Microchip for dramatic reductions in power consumption, and the 0.35um CMOS A54SX16P-2VQG100 inherits low static power from its antifuse structure, which draws no configuration-retention current. In portable analyzers and handheld instruments, the FPGA implements custom acquisition sequencing and display-interface logic at moderate clock rates where its 320 MHz capability provides timing headroom at low actual toggle activity, keeping dynamic power proportional to usage. Instant-on antifuse configuration eliminates boot delay, allowing the instrument to be measurement-ready the moment power is applied - important for battery-operated field test equipment.

What are the key specifications of A54SX16P-2VQG100 that engineers should know?
The A54SX16P-2VQG100 is a Microsemi/Microchip SX-family FPGA with 16,000 equivalent gates, 924 logic cells (1452 CLBs), a 320 MHz maximum toggle rate, and a 0.7 ns combinatorial CLB delay. It is fabricated in 0.35um CMOS, operates from 3.3V/5V supplies, and is housed in a 100-pin VQFP surface-mount package. It is antifuse one-time-programmable and RoHS compliant per distributor listings.
What is the price of A54SX16P-2VQG100?
As of 2026-09-03, A54SX16P-2VQG100 is quoted at approximately 42.50 USD for a single unit on XAIPART, with quantity breaks down to about 30.10 USD per unit at 1000 pieces. Because this device is end-of-life and single-distributor availability is reported on Octopart, actual market pricing can fluctuate; request a formal quote for volume orders.
Where to buy A54SX16P-2VQG100 online?
A54SX16P-2VQG100 can be purchased through XAIPART, DigiKey, Jotrin Electronics, and specialty brokers such as Microchip USA and Alibaba-verified suppliers. According to Octopart, pricing is available from about 1 distributor, so availability is limited for this EOL part. XAIPART supports RFQ-based ordering with traceable stock; verify date codes and authenticity when buying legacy FPGAs from brokers.
Is A54SX16P-2VQG100 in stock, and what is the lead time?
Stock status for A54SX16P-2VQG100 changes frequently because the part is discontinued (EOL). DigiKey, Jotrin, and broker channels report intermittent small-quantity inventory; Octopart lists 1 supporting distributor as of 2026-09-03. Lead time varies from in-stock shipment to several weeks depending on channel. Contact XAIPART with your required quantity for a confirmed availability and lead-time quote.
What is the difference between A54SX16P-2VQG100 and A54SX16P-2VQG100I?
The difference is the temperature grade: A54SX16P-2VQG100 is the commercial grade (0C to +70C), while the -I suffix A54SX16P-2VQG100I is the industrial grade (-40C to +85C). Both share the same SX16P die, 16K gates, 320 MHz toggle rate, -2 speed grade, and 100-pin VQFP package. Choose the -I version for outdoor, automotive-adjacent, or uncontrolled-temperature industrial environments.
A54SX16P-2VQG100 vs A54SX16P-P2VQG100 - which is better for a legacy 5V design?
For a legacy 5V mixed system, the A54SX16P-P2VQG100 is the safer choice: its P speed/grade designation denotes the 5V-tolerant I/O class within the SX16P family, and it remains housed in the same 100-pin VQFP package with identical 16K gates and 320 MHz performance. The A54SX16P-2VQG100 also supports 3.3V/5V operation, but you should confirm the exact I/O supply configuration in the datasheet for your specific rail plan before substituting either part.
When should I choose A54SX16P-2VQG100 over a modern FPGA?
Choose A54SX16P-2VQG100 when you must maintain a legacy SX-family design whose HDL, pinout, and 5V-tolerant I/O are already qualified, or when antifuse instant-on configuration (no external configuration device) and single-sourced form-fit-function replacement are required. For new designs, modern Microchip PolarFire or IGLOO devices offer lower power and higher density, but they are not drop-in replacements and require PCB and firmware changes.
Is A54SX16P-2VQG100 suitable for high-speed 320 MHz system clocking?
Yes, within limits: the A54SX16P-2VQG100 supports internal toggle rates up to 320 MHz per the SX family specifications, and its 0.7 ns combinatorial CLB delay enables fast decode and control paths. In practice, achievable system clock rates depend on routing utilization and I/O timing; designs above roughly 100 MHz system clock should be timing-verified in the Libero/Microsim design tools with the -2 speed grade timing models.
What is the best drop-in replacement for A54SX16P-2VQG100?
The best drop-in replacement is A54SX16P-2VQG100I, which uses the identical SX16P die, 100-pin VQFP package, and -2 speed grade, differing only in extended industrial temperature range. For commercial-temperature applications, A54SX16P-2VQG100PP also matches the footprint and logic resources. Because the SX16P family is one manufacturer (Microsemi/Microchip), no cross-brand pin-compatible equivalent exists in the verified data.
What is the best Microsemi/Microchip equivalent for A54SX16P-2VQG100 from other manufacturers?
No cross-brand drop-in equivalent for A54SX16P-2VQG100 was found in the verified web data. The SX antifuse FPGA architecture is proprietary to Actel/Microsemi/Microchip, and competitor FPGAs (Xilinx, Intel/Altera, Lattice) do not offer pin-compatible 100-pin VQFP equivalents for this die. Functional replacements require PCB redesign and HDL porting; for true form-fit-function continuity, source within the A54SX16P family from Microchip or authorized brokers.
Where to download the A54SX16P-2VQG100 datasheet PDF?
The A54SX16P-2VQG100 datasheet PDF (488 KB, published 2006-07-14 per FindIC) can be downloaded from the Microchip product page at microchip.com/en-us/product/A54SX16P and from datasheet aggregators such as FindIC, EEWORLD, and digchip. Always prefer the official Microchip page, as it carries the current revision of the SX family datasheet covering pinouts, timing, and programming details.
Where can I find the A54SX16P-2VQG100 pinout?
The complete 100-pin VQFP pinout for A54SX16P-2VQG100 is documented in the SX family datasheet available on the Microchip product page. It defines power (VDD, GND), dedicated I/O, and core pins with pin 1 marked at the top-left of the package body. Because we could not verify each pin assignment against the current datasheet revision, XAIPART does not reproduce the full pin table on this page - consult the official PDF before layout.
Does A54SX16P-2VQG100 need an external configuration PROM?
No. The A54SX16P-2VQG100 uses Actel antifuse programming, which is one-time-programmable and non-volatile. Configuration data is permanently written into the device at programming time, so the FPGA powers up instantly functional without a serial configuration flash or microcontroller loader. The trade-off is that any design change requires a new physically programmed device, unlike SRAM-based FPGAs that can be reprogrammed in-system.
Is A54SX16P-2VQG100 RoHS compliant and lead free?
Yes. According to distributor datasheet listings (digchip, DigiKey), A54SX16P-2VQG100 is RoHS Compliant and Lead Free. The -G suffix in the part number denotes the green/RoHS package variant relative to the original non-green SX-A parts. REACH status and halogen-free details are not explicitly stated in the verified data, so confirm with Microchip's product environmental pages for formal compliance declarations.
Hey Google, what can replace A54SX16P-2VQG100 on my existing PCB?
On an existing PCB, replace A54SX16P-2VQG100 with another A54SX16P-family part in the 100-pin VQFP package: A54SX16P-2VQG100I (industrial temperature), A54SX16P-P2VQG100 (5V-class grade), or A54SX16P-2VQG100PP. All use the same footprint and 16K-gate SX16P die, so your HDL reprograms onto the replacement without board rework. Verify speed-grade timing and temperature grade against your design environment before ordering.
What tools are used to design with A54SX16P-2VQG100?
Designs for A54SX16P-2VQG100 are implemented with Microchip's Libero SoC design suite (successor to Actel Designer), which supports Synplify synthesis, place-and-route for the SX family, and programming file generation for antifuse programming hardware. Older SX-A designs may use legacy Actel toolchains or third-party simulators with SX library models. Obtain the appropriate Libero license level from Microchip for SX support.

Selection Guide

Choose A54SX16P-2VQG100 when you need a proven 16K-gate antifuse FPGA in a 100-pin VQFP with 3.3V/5V operation for commercial-temperature (0C to +70C) equipment, particularly for legacy design sustainment, instant-on configuration, and configuration-controlled products. Choose A54SX16P-2VQG100I when the same design must operate from -40C to +85C - it is the closest drop-in with identical die and footprint. Choose A54SX16P-P2VQG100 or A54SX16P-P2VQG100I when your qualification documents specify the P2 5V-class grade. Choose A54SX16P-2VQG100PP when the PP-grade variant matches your original bill of materials. Do not choose this family for new designs: the SX16P is discontinued, one-time programmable, and limited to 16K gates - for new development, consider Microchip PolarFire or IGLOO2, accepting that PCB and HDL redesign will be required. Trade-off summary: antifuse security and instant-on versus SRAM reprogrammability; commercial price advantage versus industrial temperature margin.

Key Differentiators

  • Extended industrial temperature range (vs A54SX16P-2VQG100I)
  • Lower cost at equal logic density (vs A54SX16P-P2VQG100)
  • Non-volatile antifuse instant-on configuration (vs Modern SRAM FPGAs (e.g., PolarFire, Artix))

Design Notes

The A54SX16P-2VQG100 supports dual 3.3V/5V operation in the SX16P family, with the -2 speed grade specified at 320 MHz. Decouple each VDD pin with 0.1 uF ceramic capacitors placed within 2 mm of the pin, plus one bulk 10 uF capacitor per power rail. Estimated: dynamic power scales with toggle activity, so a design clocked at 320 MHz with low switching activity consumes far less than worst-case figures - verify with Microchip's SX power calculator using your actual net toggle rates from Libero timing reports.

The 100-pin VQFP has a 0.5 mm terminal pitch, requiring fine-pitch soldering discipline: use solder-paste stencils of 0.12-0.15 mm thickness and inspect for bridging on the quad sides. Provide a quad copper keep-out matching the TQFP-100 land pattern per the SX family datasheet. Because the device is antifuse one-time programmable, include a programming access provision (programming socket or in-circuit programming header per Actel programming hardware) on production test fixtures, since failed logic changes cannot be reflashed in place.

The most common pitfalls with SX16P designs are: (1) assuming reprogrammability - antifuse devices are one-time programmable, so validate the design fully in simulation and timing analysis before programming; (2) mixing temperature grades - the commercial A54SX16P-2VQG100 (0C to +70C) must not be substituted where the industrial A54SX16P-2VQG100I (-40C to +85C) was qualified; (3) ignoring the EOL status - the SX16P family is discontinued, so plan lifetime buys and capture the design netlist and programming files for future remanufacture.

At up to 320 MHz internal toggle rates and 0.7 ns CLB delays, output edge rates on 5V-tolerant I/O can drive reflections on long traces. Estimated: with sub-2 ns edge times, traces longer than about 25 mm on FR-4 behave as transmission lines - add 22-33 ohm series termination on high-fan-out clock and bus outputs. Keep clock routing short and matched, and reference high-speed signals to a solid ground plane to control loop area and crosstalk between adjacent 0.5 mm-pitch pins.
