A54SX16P-TQG144 概述
An antifuse FPGA is a field-programmable gate array whose interconnect elements are permanently programmed at power-up by an on-chip circuit that blows selected antifuse links. Unlike SRAM-based FPGAs from Xilinx or Altera, antifuse devices retain their configuration without any external boot memory, and their interconnect resistance and capacitance are lower, which historically gave the Actel SX family class-leading routing speed and security against design extraction.
Key features include the sea-of-modules architecture with two module types (combinatorial C-modules and sequential S-modules), 16K system gates, and a guaranteed 240 MHz toggle-rate-class performance that suits state machines, glue logic integration, and high-speed control paths. The 113 available I/O in the TQFP-144 footprint provides generous pin-out flexibility for bus interfaces.
Technically, the SX family uses a sea-of-modules fabric in which every module is surrounded by routing channels, simplifying place-and-route and shortening critical paths. The dual 3.3V/5V supply scheme allows direct interfacing with legacy 5V TTL systems while keeping core power low. Because configuration is stored in antifuse elements, startup is essentially immediate with no configuration download, improving system reliability and boot time versus SRAM FPGAs.
Typical applications include industrial control and automation, bridge and interface logic in telecom and networking equipment, 5V legacy system integration, aerospace and defense control electronics, and medical instrumentation where one-time programmability and instant-on behavior are valued.
When designing with this device, verify both supply rails meet the specified 3V to 3.6V and 4.75V to 5.25V windows, and confirm the commercial (0C to +70C, non-I suffix) temperature grade matches your environment; the -I suffix parts extend to industrial range. Remember the device is one-time programmable, so functional simulation in Libero/Designer software is essential before programming.

典型应用
A54SX16P-TQG144 适用于 6 应用s: Industrial Control and Automation, 5V Legacy System Integration and Glue Logic, Telecom and Networking Interface Logic, Aerospace and Defense Control Electronics, Medical Instrumentation, Test and Measurement Equipment.
Industrial Control and Automation
The A54SX16P-TQG144 fits industrial control systems that need deterministic, instant-on logic with 5V tolerance for legacy sensors and actuators. Its 240 MHz performance class handles high-speed state machines and sequencing, while 113 user I/O in the 144-TQFP consolidates PLC I/O interfaces, encoder counters, and interlock logic into one device. Because the antifuse configuration is non-volatile, the FPGA is functional immediately at power-up with no boot delay or configuration memory failure mode, improving machine availability. Designers should allocate margin on the 3.3V and 5V rails and use the industrial -I grade (A54SX16P-TQG144I) for factory-floor ambient temperatures.
推荐
5V Legacy System Integration and Glue Logic
Many telecom, instrumentation, and military-heritage boards still run 5V TTL buses. The A54SX16P-TQG144's dual supply (3.0V-3.6V core rail plus 4.75V-5.25V I/O rail) allows direct connection to 5V signals without level translators, cutting BOM cost and board space versus a modern FPGA plus shift-register solution. Its 16K gates replace dozens of 74-series devices for bus bridging, address decoding, and wait-state generation, and the antifuse fabric adds no configuration-download risk during brownouts. Verify each I/O standard's drive and tolerance in the SX family datasheet before connecting 5V rails to all banks.
推荐
Telecom and Networking Interface Logic
Line cards and backplane controllers in telecom equipment benefit from the A54SX16P-TQG144's combination of 240 MHz-class routing, low interconnect capacitance inherent to antifuse technology, and secure one-time programming that resists bitstream extraction. The 924 logic modules implement framing, elapse counters, and protocol handshaking, while 113 I/O map cleanly to TDM buses and PHY control interfaces in the compact 20x20 mm TQFP. Because there is no external configuration flash to read at startup, hot-swappable cards regain function immediately on insertion. Design teams should simulate worst-case timing in Libero/Designer before committing antifuse programming.
推荐
Aerospace and Defense Control Electronics
Defense subsystems value the A54SX16P-TQG144's one-time-programmable antifuse fabric, which is immune to configuration upsets that affect SRAM FPGAs and carries no external boot memory to corrupt in high-vibration environments. The 16K-gate capacity implements sensor Interfaces, safety interlocks, and watchdog logic; the instant-on behavior matters in systems with strict power-on-to-ready timing budgets. Microchip's continued support of the Actel/Microsemi antifuse line (including RTAX radiation-tolerant derivatives for space) provides a growth path. Select the industrial -I suffix for extended temperature and follow datasheet power-sequencing guidance on the dual 3.3V/5V rails.
推荐
Medical Instrumentation
Benchtop medical analyzers and imaging peripherals use the A54SX16P-TQG144 for deterministic control-plane logic, front-end timing generation, and interface consolidation. The 113 user I/O in a 20x20 mm TQFP connects ADCs, motor drivers, and panel interfaces without an external configuration device, simplifying regulatory documentation of the boot path, and the 240 MHz performance class covers high-rate acquisition sequencing. One-time programming also protects proprietary algorithms embedded in the logic from casual readback. Use the industrial-grade A54SX16P-TQG144I where the instrument must meet broader environmental qualification, and budget rail decoupling per the family datasheet.
推荐
Test and Measurement Equipment
The A54SX16P-TQG144 serves as timing-controller and glue-logic fabric in oscilloscope front ends, signal generators, and automated test fixtures where deterministic, instant-on behavior shortens instrument startup. Its sea-of-modules architecture delivers the 240 MHz-class internal routing needed for trigger state machines and counter/timer blocks, and 113 I/O accommodate measurement muxes, relay drivers, and backplane handshaking. The antifuse one-time-programmable fabric eliminates bitstream-loading jitter between power cycles, improving measurement repeatability. For designs outgrowing 16K gates, pin-similar density upgrades within the SX family and the TQFP-176 variants provide a migration route without board redesign of the control section.

设计说明
The A54SX16P-TQG144 requires two independent supply rails: 3.0V-3.6V and 4.75V-5.25V. Decouple each rail with bulk capacitance (10 uF-22 uF) plus local 0.1 uF ceramics at the package corners, placed within a few millimeters of the VDD/VSS pin pairs. Check the SX family datasheet for mandatory power-up sequencing between rails; violating sequencing can stress the 0.35 um I/O structures. Verify total current against your design's switching activity using the Microchip power estimation tools before finalizing the regulator selection.
This is an antifuse, one-time-programmable device: a design error cannot be re-flashed like an SRAM FPGA. Complete full functional and worst-case timing simulation in Microchip Libero/Designer software, and review the post-layout timing report, before committing any units to programming. Budget spare programmed units for engineering changes, since each replacement die must be reprogrammed. Also confirm the speed-grade suffix purchased (-1, standard) matches the timing model used in your design sign-off.
The 144-TQFP (20x20 mm, 0.5 mm pitch) requires fine-pitch layout practice: use 0.2 mm-0.25 mm wide traces with solder-mask-defined pads per IPC-recommended TQFP land patterns, and keep fan-out stubs short to preserve signal integrity on 240 MHz-class nets. Provide a solid ground plane under the device. Select the temperature grade deliberately: use the A54SX16P-TQG144I (-I) for environments beyond commercial range, as the commercial-grade TQG144 is not rated for extended-temperature enclosures.
