A54SX08A-2TQG144I 개요
A Field Programmable Gate Array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks (CLBs) and programmable interconnects that the designer wires together using a hardware description language such as Verilog or VHDL. Within the programmable logic hierarchy, the FPGA sits above CPLDs and PAL/GAL devices, providing higher gate counts and register-rich architecture suitable for full system-level digital integration, while antifuse FPGAs such as the SX-A family are one-time-programmable (OTP) devices.
Key features of the A54SX08A include its antifuse programming technology, which yields non-volatile, secure, single-chip operation with no external configuration PROM and very low static power. The -2 speed grade supports internal performance up to 313 MHz, and the 768-register-rich logic cells suit both combinatorial and sequential designs. The 113 available user I/Os enable glue-logic consolidation, bus interfacing, and control functions on a single low-cost device.
Architecturally, the SX-A family uses a sea-of-modules fabric built on CMOS antifuse technology. Because configuration data is hard-wired through antifuse links at programming time, the device is immune to configuration readback attacks and does not require configuration storage, improving system reliability at power-up and reducing bill-of-materials count.
Typical applications include industrial automation and control logic, military and aerospace systems requiring radiation-tolerant-adjacent, secure OTP logic, telecommunications line-card glue logic, and test and measurement instrumentation where instant-on behavior matters.
Designers should note that the A54SX08A-2TQG144I is one-time programmable: design changes require a new device, so functional simulation sign-off before programming is essential. Pricing on this page reflects distributor data as of 2026-09-03.

Industrial Automation and Control
The A54SX08A-2TQG144I fits industrial control because its industrial temperature grade, 113 user I/Os, and instant-on antifuse configuration address the core requirements of factory-floor logic: wide ambient tolerance, immediate availability at power-up, and no external configuration device that could fail. In a PLC I/O card, the 768 logic cells implement state machines, encoders/decoders, and bus interfaces between a microcontroller and field-side drivers, while the 313 MHz fabric ceiling comfortably covers typical 10-50 MHz control clock domains. Placed in the TQG144 footprint, it consolidates dozens of 74-series glue-logic packages into one chip, cutting BOM count and assembly cost. Design consideration: because the device is one-time programmable, freeze the RTL after simulation sign-off, since field firmware-style updates are impossible.
추천
Secure and Military-Grade Systems
Antifuse FPGAs are a mainstay in defense electronics because configuration is hard-wired and cannot be read back, cloned, or glitched through configuration paths - a property the SRAM-based competitors cannot match. The A54SX08A-2TQG144I provides 12,000 system gates of secure logic in a compact, solderable TQFP-144 with 113 I/Os, suited to radar interface boards, missile electronics glue logic, and secure communication line cards. Non-volatility eliminates the configuration PROM from the BOM, which removes an attack surface and improves reliability in high-shock environments. Performance is adequate for interface bridging at moderate clock rates within the 313 MHz fabric limit. Note that industrial (I) grading may not meet full MIL-temperature requirements; consult Microchip for military flow options where mandated.
추천
Telecommunications Line-Card Glue Logic
Telecom line cards historically filled with PALs, GALs, and 74-series logic; the A54SX08A-2TQG144I integrates that glue into one 12K-gate, 113-I/O device whose antifuse fabric runs comfortably above the T1/E1 and backplane clock domains in this class. Non-volatile configuration means the card enumerates and becomes active the moment power is applied - important in redundant carrier systems that must recover without a boot sequence. The TQG144 surface-mount package supports standard automated assembly, and the CMOS antifuse technology keeps static power low in always-on central-office equipment. Because one-time programming prevents post-deployment logic updates, carry spare pre-programmed devices as field-replacement units rather than attempting in-system reconfiguration.
추천
Test and Measurement Instrumentation
Bench and rack instrumentation benefits from the A54SX08A-2TQG144I's deterministic, instant-on behavior: the instrument is ready the moment power is applied because antifuse configuration requires no load cycle. The 768 logic cells implement trigger logic, counters, address decoders, and front-panel bus interfaces, while 113 user I/Os connect to ADCs, DACs, and display drivers across the TQG144 pin ring. The 313 MHz fabric capability supports fast timing measurement circuits at moderate complexity. Since measurement hardware is firmware-frozen at production and revisions occur at the board level rather than in the field, the one-time-programmable constraint is acceptable. For instruments needing more logic later, the same footprint accepts the pin-compatible A54SX32A TQG144 devices, protecting the PCB layout investment.

Legacy Design Re-Sourcing and Obsolescence Mitigation
Many mature designs were built on Actel SX-A devices and now face supply gaps; the A54SX08A-2TQG144I remains active and listed in stock at major distributors (DigiKey confirms ships-today availability as of 2026-09-03), making it a legitimate re-sourcing target for programs still using the original A54SX08A-2TQ144I-style parts. Because the SX-A family shares the TQG144 pinout across densities, buyers can also qualify A54SX32A-1TQG144I or A54SX32A-2TQG144I as second sources on the same PCB, requiring only a design recompile in Microchip Libero and reprogramming. When qualifying alternates, verify industrial temperature grading and speed grade (-1 vs -2) against timing closure, since the lower-cost A54SX08A-TQG144A differs in temperature range.
추천
Embedded Coprocessor and Bus Bridging
In embedded systems, the A54SX08A-2TQG144I works as a hardwired coprocessor bridging a host processor to peripherals whose buses the MCU cannot natively serve. The 12,000-gate fabric implements dual-port buffers, address generators, CRC units, and parallel-to-serial converters, while 113 user I/Os cover wide parallel buses plus control strobes. Because the antifuse configuration is non-volatile, the bridge is active during host boot, which simplifies power-on sequencing versus SRAM FPGAs that need a configuration controller. At 313 MHz maximum fabric speed, real-time protocol translation at tens of MHz is practical. Trade-off: OTP silicon means the bridge protocol cannot be patched; reserve this device for stable, verified interfaces and use the same-footprint A54SX32A devices when headroom is uncertain.

설계 노트
The A54SX08A-2TQG144I uses antifuse one-time-programmable technology: once programmed, the configuration is permanent and the device cannot be reprogrammed or erased. Freeze RTL after simulation and timing closure sign-off, and program a small pilot lot before committing a full production reel. Budget one extra programmed spare per system for field returns, since configuration fixes require a fresh device and a soldering operation rather than a field update.
The TQG144 TQFP has a 1.4 mm package height with fine-pitch leads - verify your land pattern against the SX-A family datasheet package section and use a 0.5 mm-pitch-compatible stencil design. Because the SX-A TQG144 pinout is shared across the A54SX08A/SX16A/SX32A family, lay out the board with the larger A54SX32A I/O assignments in mind if an in-place capacity upgrade is anticipated; unused I/O balls of smaller devices remain accessible on the same footprint.
The SX-A family operates from a low-voltage CMOS supply; confirm the exact core and I/O voltage rails in the SX-A datasheet power section before layout, and decouple each supply pin pair on the TQG144 ring with 0.1 uF ceramic capacitors placed within 2 mm of the pin, plus bulk capacitance near the package. Antifuse devices draw low static current, so thermal design is usually trivial - a solid ground plane under the package suffices at 12K-gate utilization levels.
With up to 313 MHz internal fabric capability, keep clock routing short and series-terminate long lines leaving the package at speed-grade-relevant frequencies. The 113 user I/Os share TQFP lead inductance with ground returns; assign switching-heavy outputs to pins adjacent to ground/power pins in your pinout file to reduce simultaneous-switching noise, which matters more on QFP packages than on flip-chip BGAs in the same family.
