A54SX72A-PQG208I - 108K-Gate Antifuse FPGA 208-PQFP | Microchip
MPN： A54SX72A-PQG208I ✓ 啟用中A54SX72A-PQG208I 概覽
An antifuse FPGA is a field-programmable gate array in which programmable interconnects are one-time-programmable antifuse elements. Unlike SRAM-based FPGAs, antifuse devices retain their configuration permanently with no external boot configuration memory, which reduces bill-of-materials cost, shortens power-up time, and improves design security because the bitstream is never stored externally. In the programmable logic hierarchy, the A54SX72A sits within the FPGA class alongside one-time-programmable and reprogrammable fabric devices.
Key features include a 2.5V core supply with I/O supply support from 2.25V to 5.25V per distributor data, enabling direct interfacing with 3.3V and 5V legacy logic families. The segmented routing architecture delivers predictable interconnect delays, supporting the 217 MHz toggle capability reported by distributors. The non-volatile antifuse fabric also offers low static power consumption and inherent resistance to configuration readback attacks.
The device is fabricated on a 0.25 um process and organized into logic modules with multiplexer-based combinational cells and register cells, a structure suited to wide-decode, state-machine, and glue-logic integration. Quadrant clock inputs (A, B, C, D per the Microchip SX-A datasheet) support multiple low-skew clock domains.
Typical applications include industrial control and automation, communications line-card glue logic, aerospace and defense single-board computers where configuration volatility is unacceptable, and cost-reduction ASIC prototypes or bridge logic consolidating multiple ASSPs into one chip.
Design consideration: because antifuse FPGAs are one-time programmable, thoroughly complete simulation and timing verification in Libero SoC before programming, and budget the programming service or in-house programmer into your production flow.

典型應用
A54SX72A-PQG208I 適用於 6 應用s: Industrial Control and Automation, Aerospace and Defense Single-Board Computing, Communications Line-Card Glue Logic, ASIC Prototyping and Bridging, Medical Instrumentation Control Logic, Secure Embedded Controllers.
Industrial Control and Automation
The A54SX72A-PQG208I fits industrial control systems that need deterministic glue logic, wide address decoding, and motor-interface state machines in one low-cost device. Its 108K system gates consolidate multiple CPLDs or ASSPs, and the 171 user I/Os with 2.25V to 5.25V supply tolerance interface directly with 3.3V and 5V PLC I/O standards without level shifters. The antifuse fabric powers up instantly with configuration resident in silicon, eliminating boot delays in safety-interlocked machinery. Because the programmed interconnect is permanent, field firmware corruption from configuration memory upsets is not a failure mode. Use Libero SoC to close timing at your clock rate and exploit quadrant clock inputs (A, B, C, D per the SX-A datasheet) for independent low-skew clock domains driving counters and communication sequencers.
推薦
Aerospace and Defense Single-Board Computing
Defense single-board computers and payload controllers favor the A54SX72A-PQG208I because the antifuse configuration cannot be read back, protecting proprietary or mission-critical logic from extraction. The device's instant-on behavior means bridge logic and bus interfaces are active before a host processor completes reset, simplifying power sequencing. The PQG208M military-grade variant of the same die supports programs needing the wider qualification range. With 108K system gates, the device implements PCI bridges, memory controllers, and custom bus interfaces; the 217 MHz capability from distributor data supports fast decode and FIFO timing. Designers should budget one-time programming into the production flow since respins require new devices, and should verify radiation and program-level requirements directly with Microchip for space-adjacent programs.
推薦
Communications Line-Card Glue Logic
Telecom and datacom line cards use the A54SX72A-PQG208I to consolidate address decoding, interrupt control, JTAG boundary access, and backplane interface state machines. The segmented antifuse routing gives predictable interconnect delay, which simplifies meeting backplane timing budgets at the 217 MHz class speeds the family supports. The 171 user I/Os in a 208-pin PQFP (28 x 28 mm) provide enough pins for a 32/64-bit local bus plus status LEDs and management signals. Because the configuration is non-volatile, line cards resume operation immediately after hot-swap or brown-out events without reconfiguration controllers or serial flash. Quantify static power savings versus an SRAM FPGA at the same density when the card must operate within a fixed slot power budget.
推薦
ASIC Prototyping and Bridging
The A54SX72A-PQG208I serves as a bridge device while a companion ASIC is developed, implementing bus translation, clock-domain crossing logic, and test interfaces on the same board that later hosts the ASIC. The 108K system gate capacity and 6,036 logic modules absorb moderate RTL blocks, and the antifuse fabric delivers timing closer to a masked ASIC than SRAM FPGA prototypes because there is no configuration-cell loading on routing. Distributor-reported 217 MHz operation supports common peripheral clock rates. Using the 208-pin PQFP simplifies prototype rework with standard SMT assembly compared with fine-pitch BGAs. Plan the programming service lead time into the prototype schedule, since each silicon iteration requires fresh antifuse devices and a fixed design freeze point in Libero SoC.
推薦
Medical Instrumentation Control Logic
Medical diagnostic instruments use the A54SX72A-PQG208I for sensor-interface sequencing, motor and valve control, and safety interlock logic where deterministic power-up matters. The non-volatile antifuse configuration ensures the control fabric is functional the moment power is applied, supporting self-test routines that must run before an operating system loads. With 171 user I/Os tolerant across the 2.25V to 5.25V supply range per distributor data, the device connects legacy 5V sensor heads and modern 3.3V microcontroller subsystems without extra translation ICs, reducing board area in portable instruments. The one-time-programmed logic also simplifies design-change control for regulatory documentation: the shipped configuration is bitstream-final and auditable. Verify the industrial temperature grade matches your instrument's specified operating range.
推薦
Secure Embedded Controllers
Security-focused embedded controllers adopt the A54SX72A-PQG208I where the configuration must be physically immune to readback. Unlike SRAM FPGAs that store bitstreams in external flash susceptible to interception, the antifuse interconnect exists only in silicon, and Microchip positions the SX-A family on security as well as low power. The 108K system gates implement authentication state machines, tamper-response sequencing, and secure boot supervision alongside general glue logic, while 171 user I/Os cover sensor, keypad, and communication interfaces. Instant-on behavior lets the security fabric monitor power rails before a host processor starts. Designers should pair the device with Microchip's secure authentication ICs and validate the full threat model, since antifuse security addresses configuration extraction, not runtime side-channel attacks.

設計說明
The SX72A die operates from a 2.5V core supply; per distributor data the supply range spans 2.25V to 5.25V, so design your power tree around the SX-A datasheet per-bank rules for the 171 user I/Os. Estimated: at 108K gates of moderate utilization, expect static power far below an equivalent SRAM FPGA since there is no configuration bit-cell leakage, but confirm with Libero SoC power analysis for your netlist rather than relying on family averages. Decouple VCC and VCCA with bulk plus 0.1 uF ceramic caps at each supply pin group.
The device is one-time programmable: after antifuse programming there is no way to correct logic errors without scrapping the silicon. Complete functional simulation, post-layout timing simulation, and formal equivalence checks in Microchip Libero SoC before releasing the programming file. Reserve spare I/Os in your pin assignment for future debug access, and lock your pinout early because the 208-PQFP pinout cannot be changed after the PCB is fabricated.
The 208-PQFP (28 x 28 mm) gull-wing package requires careful footprint design per IPC-compatible land patterns: verify lead pitch against the Microchip package drawing before ordering the PCB. Use the quadrant clock inputs A, B, C, D (bottom-left, bottom-right, top-left, top-right per the SX-A datasheet) for low-skew clock distribution; route each clock source to the nearest quadrant pin and keep clock traces short with series termination to limit ringing at 217 MHz class edge rates.
