A54SX16P-2TQG144 Présentation
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks (CLBs), programmable interconnect, and user-programmable I/O that designers configure after manufacturing. Within the programmable logic hierarchy, the SX family sits among antifuse-based, high-speed, one-time-programmable FPGAs positioned above simple CPLDs and below large scale-of-integration families such as RTAX, making it suited for performance-intensive glueless logic integration.
Key features include the sea-of-modules architecture that simplifies timing-driven design, dual 3.3V/5V supply operation for interfacing with 5V legacy systems, and deterministic antifuse interconnect that delivers predictable routing delays - a significant advantage over SRAM FPGAs where routing delay varies with placement. The 113 available user I/O within the 144-pin TQFP provides a strong I/O-to-logic ratio for bus-intensive designs.
Technically, the SX family uses a 0.35 um antifuse CMOS process whose proprietary metal-to-metal antifuse elements are programmed once at power-up configuration, making the device non-volatile, secure against readback, and immune to configuration-bit upsets - attributes valued in industrial and defense-adjacent systems.
Typical applications include industrial control and automation logic, telecommunications line-card glue logic, 5V-tolerant bus bridging, test and measurement instrumentation, and obsolescence-driven redesigns replacing multiple TTL/PLD devices.
When designing with this device, verify that the 5.25V maximum I/O rail tolerance and one-time-programmable (OTP) workflow fit your production model, since design changes require new devices rather than reconfiguration.

Applications typiques
A54SX16P-2TQG144 convient pour 6 applications: Industrial Control and Automation, 5V Legacy Bus Bridging, Telecommunications Line-Card Logic, Test and Measurement Instrumentation, Defense and High-Reliability Upgrades, Obsolescence-Driven Redesign.
Industrial Control and Automation
The A54SX16P-2TQG144 fits industrial control and factory automation designs that need deterministic, glueless integration of PLC I/O logic, encoders, and machine-state sequencers. Its 24,000 gates and 924 logic cells consolidate dozens of 74xx and PLD devices into one antifuse FPGA, while 113 user I/O directly interface 5V industrial sensors and actuators via the 4.75V-5.25V I/O rail. Because antifuse configuration is non-volatile and immune to configuration-bit upset, the FPGA is immediately active at power-up with no configuration device - valuable on factory floors with noisy power. Deterministic routing delays simplify meeting fixed-cycle timing budgets in motion-control state machines.
Recommandé
5V Legacy Bus Bridging
Legacy backplanes, VME-style racks, and older test fixtures still run 5V TTL signaling that modern FPGAs cannot tolerate. The A54SX16P-2TQG144 addresses this directly: its I/O supply is specified at 4.75V to 5.25V, allowing the 113 user I/O to drive and receive full 5V logic levels without level shifters or series resistors. Designers typically map the FPGA between the legacy 5V bus and a modern 3.3V processor section, using the 24,000 gates for bus arbitration, byte-swap glue, and interrupt aggregation. The one-time-programmable nature also prevents accidental reconfiguration of deployed bridge hardware, an advantage over SRAM FPGAs in long-life fielded systems.
Recommandé
Telecommunications Line-Card Logic
Telecom line cards in legacy CO equipment and transmission systems rely on fast, deterministic glue logic for framing, HDLC-lite aggregation, and backplane interfacing. The A54SX16P-2TQG144's SX architecture supports system speeds up to 320 MHz on a 0.35 um process, sufficient for high-speed counter chains and synchronous state machines, while the antifuse routing gives fixed delays that ease timing closure across board revisions. The dual 3.3V/5V supply matches the mixed-rail reality of telecom shelves: 3.3V core logic plus 5V-legacy backplane signaling. Its 113 user I/O in a compact 20x20 mm TQFP suits high-density card layouts where board area is constrained.
Recommandé
Test and Measurement Instrumentation
Bench and rack instrumentation frequently needs custom timing generators, event counters, and protocol-aware trigger logic between front-end circuitry and a processor. The A54SX16P-2TQG144 suits these roles with its 320 MHz capability, deterministic antifuse delays, and 113 5V-tolerant I/O that connects directly to legacy instrumentation front ends. Its 24,000-gate capacity comfortably hosts multi-channel trigger state machines and prescaler chains. The non-volatile antifuse configuration means instruments power into a known operational state with zero boot latency - important for instruments that must begin capturing immediately at power-on. Same-footprint SX32 parts provide an upgrade path when instrument features grow.

Defense and High-Reliability Upgrades
For defense-adjacent and high-reliability programs maintaining fielded hardware, the A54SX16P-2TQG144 and its M-grade sibling A54SX16P-1TQG144M extend the SX antifuse architecture into environments where configuration-upset immunity and readback security are mandatory. Antifuse devices hold their configuration through radiation-induced and power-cycling events that can corrupt SRAM configuration memory, and there is no bitstream to read back or intercept. The 144-TQFP (20x20 mm) package suits board upgrades of existing line-replaceable units, and the same-footprint family (SX08/SX16P/SX32) lets one PCB layout span multiple program variants with only a different programmed device installed.
Recommandé
Obsolescence-Driven Redesign
When EOL gate arrays, PLDs, or multi-chip TTL logic must be consolidated onto a single available device, the A54SX16P-2TQG144 offers a practical landing zone: still stocked by distributors as of 2026-09-03, with same-package family members (A54SX16P-2TQG144I, A54SX32-2TQG144) providing second sources within one footprint. Its 5V I/O rail absorbs legacy-interface requirements without level translation, while 24,000 gates swallow typical random glue logic, bus arbiters, and decoders from obsolete boards. Designers should perform a last-time-buy assessment early, because the SX family is EOL and long-term supply beyond current distributor stock is broker-dependent.

Principaux différenciateurs
- Fastest commercial speed grade in the 144-TQFP SX16P family (vs A54SX16P-1TQG144M)
- Native 5V I/O operation without level shifters (vs Modern SRAM FPGAs (e.g., Microchip PolarFire/SmartFusion))
- Configuration-upset immunity via antifuse OTP (vs A54SX16P-2TQG144I (comparison within family))
Notes de conception
The A54SX16P-2TQG144 requires two supply rails: 3V-3.6V for the core and 4.75V-5.25V for I/O. Sequence or decouple them independently - place 100 nF ceramic capacitors at each supply pin pair plus one bulk 10 uF per rail. In 5V bus designs, ensure the I/O rail never exceeds 5.25V including load transients, since the 0.35 um antifuse I/O structures have no modern overvoltage tolerance headroom. Estimated: at full logic toggle the SX16P core current is on the order of tens of milliamps; size the 3.3V regulator accordingly rather than assuming amp-level loads.
The 144-pin TQFP (20x20 mm) has 0.5 mm pitch leads requiring a well-defined solder stencil; use a 1:1 or slightly reduced aperture with paste at all 144 lands. Provide an exposed copper flood under the package center tied to ground for thermal relief and return paths. Route 5V-tolerant I/O traces with at least 0.2 mm clearance to adjacent 3.3V-domain signals. Keep unused I/O configured as inputs with pull resistors or drive them low in the design to avoid floating inputs on this OTP device - once programmed, I/O behavior is permanently fixed.
The most common SX-family pitfall is treating it like an SRAM FPGA: the antifuse device is one-time programmable, so any logic fix in production requires new physical parts and a reprogramming cycle. Freeze the netlist before ordering programmed production units and budget spares. Second pitfall: configuration programming requires specific programming voltage and socket procedures per the manufacturer programming tools - do not assume JTAG in-system programming. Third: verify the -2 speed grade timing at your operating temperature if moving to the I-grade variant, since derating applies across temperature grades.
