A54SX16P-2TQG176I - 16K Gate SX FPGA 320MHz TQFP-176 | Microchip
MPN: A54SX16P-2TQG176I ✓ Hoạt độngA54SX16P-2TQG176I Tóm tắt
An FPGA is a reconfigurable semiconductor device whose logic function is defined at design time rather than fixed at fabrication. Within the digital logic hierarchy, the FPGA sits above fixed-function ASICs and ASSPs: it belongs to the programmable logic family, alongside CPLDs and programmable SoCs, and is a core building block of embedded system and power management architectures.
Key features of the A54SX16P include the SX sea-of-modules architecture, which simplifies timing-driven design, reduces design cost and power consumption, and shortens time to market for performance-intensive applications. The device provides 1452 LABs/CLBs of configurable logic, 0.35 um CMOS process technology, and speed grade -2, balancing performance and cost. The P-suffix variant supports antifuse-based one-time programmability, delivering design security and radiation-tolerant behavior valued in industrial and aerospace-derived systems.
Technically, the SX family uses a sea-of-modules structure with dedicated registers and carry logic for arithmetic, achieving predictable interconnect delays. The 320 MHz maximum clock frequency and 147 programmable I/O make it suitable for glue logic consolidation, bus interfacing, protocol bridging, and control state machines in embedded systems. Industrial-grade (I) temperature rating supports extended-environment deployments.
Typical applications include industrial automation control, communications and networking interface bridging, and military/aerospace-derived or high-reliability industrial systems where one-time-programmable antifuse security matters.
A key design consideration: antifuse FPGAs are one-time programmable, so designers must fully validate the bitstream before programming production units, and Libero SoC design software from Microchip is required for synthesis and place-and-route.

Ứng dụng tiêu biểu
A54SX16P-2TQG176I phù hợp cho 6 Áp dụngs: Industrial Automation Control, Communications and Networking Interfaces, High-Reliability and Aerospace-Derived Systems, Test and Measurement Equipment, Embedded Control and Glue Logic Consolidation, Power Management and Sequencing Supervision.
Industrial Automation Control
The A54SX16P-2TQG176I fits industrial automation because its industrial temperature rating, 147 user I/O, and 320 MHz class logic cover PLC I/O scanning, motor control state machines, and sensor interfacing. The sea-of-modules architecture delivers deterministic interconnect delays, simplifying timing closure for fixed-cycle control loops. Used to consolidate glue logic, bus interfaces, and counters, it replaces dozens of discrete 74-series devices, reducing board area and power. Its one-time-programmable antifuse configuration cannot be corrupted by noise-induced single-event upsets of SRAM configuration memory, an important reliability benefit on electrically noisy factory floors near drives and contactors.
Được đề xuất
Communications and Networking Interfaces
In communications equipment, the A54SX16P-2TQG176I serves as a protocol bridge and line-card glue logic device. The -2 speed grade supports the 320 MHz toggle capability needed for parallel data framing, clock-domain crossing FIFOs, and serial shift logic, while 147 I/O pins accommodate wide parallel backplanes. The 3.3V core with 5V-tolerant I/O eases integration with legacy telecom line cards. Because the antifuse configuration is permanent, the design is immune to configuration-bit corruption and resists reverse engineering, a consideration for network equipment vendors protecting proprietary framing algorithms deployed in the field.

High-Reliability and Aerospace-Derived Systems
The A54SX16P antifuse family is a common choice in high-reliability industrial and aerospace-derived programs. One-time-programmable antifuse technology eliminates configuration storage devices, reducing BOM count and removing the most common SEU failure point of SRAM FPGAs. The I temperature suffix and mature 0.35 um CMOS process provide well-characterized behavior across temperature and over long mission durations. Designers typically use the device for telemetry formatting, redundancy voting logic, and power sequencing supervision, where the 16K gate capacity is sufficient and design data security after programming is mandatory for program qualification.

Test and Measurement Equipment
Bench and rack instrumentation uses the A54SX16P-2TQG176I for trigger generation, counter/timer functions, and bus interfacing (GPIB, RS-232/485 framing) behind the front-end. The 924 cells provide enough capacity for multi-channel edge detectors and timestamping logic, while the 320 MHz class performance supports high-resolution event timing. The 176-pin TQFP with 0.5 mm class lead pitch is hand-solderable for prototype rework, valuable in low-volume instruments. Deterministic antifuse interconnect means measured trigger latency is stable unit-to-unit, supporting instrument calibration repeatability across production runs.

Embedded Control and Glue Logic Consolidation
For embedded controllers, the A54SX16P-2TQG176I consolidates address decoding, wait-state generation, interrupt prioritization, and level-conversion bridges between a host CPU and peripherals. The 3.3V/5V tolerant I/O mix lets it interface legacy 5V buses directly, a frequent requirement when reviving mature platforms without a full redesign. The 16K gate capacity covers these functions plus DMA handshake logic with headroom. Because the configuration is permanent, firmware teams treat the FPGA as fixed hardware, simplifying configuration management: no boot-time bitstream download, no configuration flash to program or fail in the field.
Được đề xuất
Power Management and Sequencing Supervision
Multi-rail systems use the A54SX16P-2TQG176I as a sequencing and supervisor engine: its I/O monitor power-good signals, drive enable pins of regulators, and implement reset trees with programmable delay counters. The 3.0V to 3.6V supply range matches standard 3.3V rails, and the antifuse programming ensures the sequencing behavior is locked and auditable, which simplifies safety reviews. Deterministic logic delays support precise rail-to-rail delay windows, while the 147 I/O allow supervision of many independent rails on dense boards such as baseband cards and industrial drives, replacing several dedicated supervisor ICs.

Ghi chú thiết kế
Supply the A54SX16P-2TQG176I core from a clean 3.3V rail within the 3.0V to 3.6V range. Decouple each VCC/VCCA pin pair with 0.1 uF ceramic capacitors placed within 2 mm of the pin, plus bulk 10 uF per power domain. Power is design-dependent, so run Microchip Libero SoC power analysis with your actual toggle rates; do not assume worst-case datasheet numbers. Estimated: a mid-density design toggling at moderate rates typically draws a few tens of mA at 3.3V, but verify per design.
The 176-pin TQFP uses fine lead pitch, so specify a solder-mask-defined land pattern per the package mechanical drawing and inspect for bridging after reflow. Route unused I/O as inputs with internal pull-up/down assignment in Libero SoC, or tie to defined levels on the board. Keep high-speed clock traces short and referenced to a solid ground plane; the 320 MHz class toggle capability makes sloppy clock routing a real EMI risk. Use 0.5 mm-class pitch breakout via fanout only where unavoidable under the package.
This is a one-time-programmable antifuse FPGA: a bitstream cannot be corrected after programming. Complete full simulation and static timing analysis in Libero SoC, and program a pilot lot for functional verification before committing production quantity, because misprogrammed units are unrecoverable. Also, do not interchange the P and non-P variants blindly in certification-controlled programs - re-verify timing and programming qualification, and confirm the I temperature suffix matches your environmental requirement.
