A54SX08A-1TQG144 개요
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable routing, allowing engineers to implement custom digital circuits after manufacturing. Within the programmable logic hierarchy, the A54SX08A sits in the low-to-mid density one-time-programmable (OTP) FPGA class, positioned below SRAM-based FPGAs but offering instant-on startup, no external configuration PROM, and inherent design security because the antifuse bitstream cannot be read back.
Key features include 768 configurable logic cells (approximately 12,000 equivalent system gates, of which roughly 8,000 are typically usable), 113 available user I/O, and a supply range of 2.25 V to 5.25 V tolerance on the listed variant data with a nominal 2.5 V core. The SX-A architecture delivers deterministic, high-speed routing suitable for glue logic consolidation, state machines, and bus interface bridging at 100+ MHz.
Technically, the device uses Microsemi/Microchip antifuse interconnect elements that permanently set routing at programming time, eliminating configuration time and single-event configuration-upset concerns in space- and security-sensitive systems. Speed grade -1 devices support system-level clocks up to 278 MHz on critical paths, and the 0.25 um process balances cost against performance.
Typical applications include industrial control sequencing, telecommunications line-card glue logic, embedded system bus translation (PCI, VME companion logic), and defense electronics requiring instant-on, tamper-resistant programmable logic.
Design consideration: because this is an OTP antifuse device, functional errors cannot be re-programmed in place; verify your design thoroughly in simulation and, ideally, with a development device before committing production units.

일반적인 애플리케이션
A54SX08A-1TQG144 적합 용도: 6 애플리케이션s: Industrial Control and Automation, Defense and Secure Electronics, Glue Logic Consolidation, Telecommunications Line Cards, Bus Interface Bridging, Aerospace Avionics Companion Logic.
Industrial Control and Automation
In factory automation and industrial controllers, the A54SX08A-1TQG144 consolidates address decoding, sequencer state machines, and I/O handshaking that would otherwise occupy several PAL/GAL devices. Its 12,000-gate capacity and 113 user I/Os cover typical PLC companion-logic needs, while the 278 MHz maximum toggle frequency far exceeds the 10-50 MHz timing demands of industrial buses. Because the antifuse configuration is permanent, the FPGA starts functioning within microseconds of power application - critical for machinery requiring deterministic startup - and cannot be corrupted by power glitches or configuration-memory upset, improving uptime in electrically noisy motor-drive environments.
추천
Defense and Secure Electronics
The A54SX08A-1TQG144 fits defense electronics where design security and instant-on behavior matter. Antifuse programming means the bitstream cannot be read back, protecting proprietary or mission-critical IP, and there is no SRAM configuration memory vulnerable to single-event or malicious upset. The device implements encryption key handling logic, sensor preprocessing, and bus interface bridges with deterministic 2.5 V core timing up to 278 MHz. Its permanent configuration also eliminates boot-time attack windows present in SRAM FPGAs. For programs requiring extended temperature screening, the -I and screened suffix variants in the same 144-TQFP footprint qualify without PCB redesign.
추천
Glue Logic Consolidation
A primary use of the A54SX08A-1TQG144 is replacing dozens of 74-series logic devices, PALs, and GALs with one chip. With 768 logic cells and 113 I/Os, a single device absorbs address decoders, bus transceivers with parity, wait-state generators, and interrupt controllers, cutting BOM count, board area, and assembly cost. The SX-A family was explicitly positioned by Microchip for low-cost single-chip integration savings. Unlike CPLDs with fixed macrocell structures, the FPGA routing flexibly accommodates irregular logic, and the 0.25 um antifuse process provides cost-effective density for mid-complexity consolidation projects.
추천
Telecommunications Line Cards
In telecom line-card designs, the A54SX08A-1TQG144 implements framer glue logic, backplane interface translation, and supervisory state machines between PHY devices and system processors. The 278 MHz toggle capability supports OC-3 class auxiliary clocking, and the permanent antifuse configuration ensures the card is operational the moment slots are powered - valuable in redundant, hot-swappable architectures. Its low NRE cost (no mask charges) makes it economical for mid-volume line cards, and the 144-TQFP with 0.50 mm pitch fits the dense card geometries typical of ATCA and legacy CompactPCI form factors.
추천
Bus Interface Bridging
The A54SX08A-1TQG144 serves as a bridge between legacy system buses (VME, ISA, PC/104, PCI companion logic) and modern processors or ASICs. With 113 user I/Os, wide data paths up to 32 bits plus full address and control signaling route through one device, and the -1 speed grade's 278 MHz maximum toggle frequency covers 33 MHz PCI-class timing with margin. The one-time-programmable architecture guarantees fixed protocol timing behavior with no reconfiguration latency, which simplifies system certification. Designs that later outgrow 12,000 gates migrate to A54SX16A-1TQG144 on the identical PCB footprint without layout rework.
추천
Aerospace Avionics Companion Logic
In avionics subsystems, the A54SX08A-1TQG144 provides ARINC 429 companion logic, discrete-to-digital conversion, and voter/comparator functions where deterministic, radiation-robust configuration is required. The antifuse fabric has no configuration bitstream to upset, giving inherent tolerance to configuration-corruption mechanisms compared with SRAM FPGAs, and instant power-up meets avionics BIT (built-in-test) timing budgets. The 2.5 V core keeps dynamic power low for constrained platforms, while 12,000 gates accommodate moderate protocol and monitoring logic. Temperature-screened -I and A-suffix variants in the same 144-TQFP support program qualification flows.

설계 노트
The A54SX08A-1TQG144 is a one-time-programmable antifuse FPGA: once programmed, errors cannot be corrected in the field. Complete gate-level timing simulation of the routed netlist in Libero before programming production units, and validate the design on an engineering-lot device first. Budget for scrap/rework in yield calculations, and keep an unprogrammed spare-quantity buffer because a single mis-programmed device is unrecoverable.
The 2.5 V core supply must be clean and within tolerance at all times, including during programming. Provide local decoupling (100 nF ceramic per power pin group plus bulk 10 uF) and ensure the programming power supply can source required current. I/O bank voltage requirements depend on the selected I/O standard; consult the SX-A datasheet tables before assigning 3.3 V or 5 V tolerant standards to the 113 user I/Os.
The 144-TQFP has a 0.50 mm pin pitch - fine-pitch but hand-assemblable with care. Design land patterns per the Microchip recommended footprint in the family datasheet, and route I/O with controlled impedance where timing-critical buses exceed a few inches. The TQFP thermal pad is the package body; a modest 2x2 inch copper pour keeps junction temperatures safe at the low switching activity typical of glue-logic duty cycles. Estimated thermal performance: at ~0.25 W dissipation and roughly 60-90 C/W theta_JA typical for 144-TQFP, junction rise is only about 15-25 C above ambient.
For clocks near the 278 MHz toggle limit, use short, direct routes from the clock source to the dedicated clock-entry pins identified in the datasheet pin tables. Avoid daisy-chaining clock signals across I/O; SX-A clock resources provide low-skew global routing. Series-terminate (22-33 ohm) drive pins on long lines to reduce reflections and EMI with the 0.25 um output edge rates.
규정 준수 정보
