A54SX72A-FG484A - 108K-Gate Antifuse FPGA, 360 I/O | Microchip
MPN: A54SX72A-FG484A ✓ Hoạt độngA54SX72A-FG484A Tóm tắt
An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing internal antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, immune to configuration readback, and require no external configuration ROM, placing them in the programmable logic hierarchy alongside flash-based and SRAM FPGAs as one-time-programmable (OTP) logic devices.
Key features of the A54SX72A-FG484A include a 0.25 um process technology, system-level performance up to 217 MHz for the -A speed grade, 4,024 logic cells, and 360 available user I/O in the 484-ball FBGA footprint. The SX-A architecture uses a sea-of-modules structure with C-cells for combinatorial logic and R-cells for registered logic, supported by multiple global clock networks including CLKA, CLKB, and quadrant clock (QCLK) resources for low-skew clock distribution.
The device integrates multiple functions into a low-cost, single-chip solution, delivering performance, security, and low power. Because the antifuse configuration is permanent and cannot be read back, the A54SX72A-FG484A offers inherent design security, a key differentiator versus SRAM FPGAs. Supply voltage tolerance of 2.25V to 5.25V simplifies mixed-voltage board design.
Typical applications include glue logic integration, bus interfacing, industrial control, communications equipment, and aerospace/defense systems requiring non-volatile, secure, single-chip programmable logic, where the SX-A family decreases the premium for performance.
Design consideration: antifuse FPGAs are one-time programmable - there is no design iteration on the same physical device, so verify timing and functionality thoroughly in simulation before programming production units.

Ứng dụng tiêu biểu
A54SX72A-FG484A phù hợp cho 6 Áp dụngs: Glue Logic Integration, Aerospace and Defense Systems, Industrial Automation and Control, Communications and Networking Equipment, Test and Measurement Instrumentation, Secure Embedded Controllers.
Glue Logic Integration
The A54SX72A-FG484A consolidates discrete PAL/GAL/ASSP glue logic into a single 108,000-gate antifuse device, reducing board area and BOM cost. Its 360 user I/O in the 484-FBGA package supports wide address/data buses, and immediate power-up operation from non-volatile antifuse configuration removes boot-time configuration delays. The 2.25V to 5.25V supply tolerance eases integration into mixed-voltage legacy backplanes, making it a cost-effective single-chip replacement for multi-chip TTL/PLD clusters in industrial controllers.
Được đề xuất
Aerospace and Defense Systems
Antifuse FPGAs are favored in aerospace and defense payloads because their one-time-programmed interconnect cannot be read back, upset by configuration errors, or altered in flight. The A54SX72A-FG484A provides 108K gates of secure, non-volatile logic with quadrant clock (QCLK) networks for deterministic timing across submodules. For space programs, Microchip offers the related RT54SX72S radiation-tolerant variant; for defense ground systems the industrial -I grade covers -40C to +85C with the same footprint.
Được đề xuất
Industrial Automation and Control
In factory automation, the A54SX72A-FG484A implements deterministic sequencers, encoder interfaces, and fieldbus glue logic with 217 MHz (-A grade) internal performance. The non-volatile antifuse configuration starts instantly on power-up with no configuration controller, improving system availability, and immunity to configuration readback protects proprietary control IP. The 2.25V to 5.25V operating range supports 5V and 3.3V industrial I/O standards common on PLC backplanes, and the 484-FBGA offers 360 I/O for dense sensor/actuator aggregation.
Được đề xuất
Communications and Networking Equipment
Line cards and telecom backplane adapters use the A54SX72A-FG484A for bus bridging, framer interfacing, and control-plane logic. Multiple global and quadrant clock resources (CLKA, CLKB, QCLK) support multi-domain designs, while the 0.25 um antifuse process delivers low static power compared with SRAM FPGAs of similar capacity. The wide 360-I/O count in 484-FBGA handles parallel PHY interfaces, and one-time programmability guarantees the firmware image is immutable in deployed network hardware.
Được đề xuất
Test and Measurement Instrumentation
Bench and automated test equipment integrates the A54SX72A-FG484A for timing generators, trigger logic, and instrument backplane arbitration. The -A speed grade supports up to 217 MHz internal operation for high-resolution timing functions, and 4,024 logic cells with 360 I/O accommodate pattern generators and capture engines. Non-volatile startup ensures instruments are operational immediately at power-on, and the secure antifuse fabric protects proprietary measurement algorithms from extraction.
Được đề xuất
Secure Embedded Controllers
Applications requiring intellectual-property protection use the A54SX72A-FG484A because antifuse bitstreams cannot be dumped or cloned, unlike SRAM FPGA configuration memories. The device implements secure state machines, authentication glue, and interface translation with zero configuration footprint on the PCB - no serial flash, no load sequencer. With 108K gates and immediate power-up behavior, it suits secure embedded controllers in payment terminals, access-control hardware, and proprietary industrial equipment.

Ghi chú thiết kế
The A54SX72A-FG484A operates from a 2.25V to 5.25V supply, but antifuse programming requires dedicated VPP/VM programming-voltage balls defined in the SX-A datasheet package tables. Provide clean, low-ESR bulk and 0.1 uF ceramic decoupling at every VCC ball of the 484-FBGA. Estimated: with 360 I/O, allocate decoupling at a ratio of at least one 0.1 uF capacitor per four supply balls to control di/dt ground bounce on wide bus switching.
Antifuse devices are one-time programmable - a design change requires a new physical device. Complete full post-place-and-route timing simulation and verify quadrant clock (QCLK) placement before submitting any unit to programming. Per the SX-A datasheet, A54SX72A quadrant clock usage differs from full-device global clocks (CLKA/CLKB); refer to Microchip's quadrant clocks application notes for the A54SX72A to avoid low-skew violations across clock domains.
The 484-FBGA requires a matched 484-ball land pattern per the SX-A datasheet footprint drawing; all alternatives on this page share the identical footprint, enabling a single PCB layout to source any A54SX72A 484-FBGA grade. Escape routing at 1.0 mm-plus ball pitch allows standard 4-mil trace/space; keep VPP/VM programming nets short and isolated from sensitive I/O to prevent programming-voltage coupling.
Operating temperature for the A grade is 0C to +70C; for environments outside this window select the FG484I (-40C to +85C) or FGG484M variants, which are pin-compatible. Estimated: at moderate gate utilization (under 40%) and low toggle rates typical of glue-logic designs, the 0.25 um antifuse fabric dissipates low static power, but verify with Microchip's power tools for your routed design rather than assuming headroom.
Thông tin tuân thủ
