A54SX16-TQG176 개요
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements digital logic through a fabric of configurable logic blocks and interconnects programmed by the user rather than fixed at the fab. The SX family uses a sea-of-modules antifuse architecture: one-time programmable interconnects set permanently at programming time, which removes the configuration storage (SRAM cells or flash) required by reprogrammable FPGAs. This places the SX family in the wider hierarchy of FPGA -> programmable logic -> programmable SoC/system logic, and the antifuse approach gives it instant-on behavior, low static power, and inherent resistance to configuration bitstream capture.
Key features include a dual supply rail of 3V to 3.6V core/I-O plus a 4.75V to 5.25V programming/5V-tolerant supply, 1452 LABs/CLBs, commercial-grade operation from 0C to +70C, and RoHS3-compliant lead-free construction. The 0.35 um process supports system speeds up to roughly 240-320 MHz depending on speed grade, and the antifuse fabric delivers deterministic, low-jitter routing well suited to glue logic consolidation.
Technically, the sea-of-modules architecture shortens interconnect paths versus channel-based FPGA architectures, which simplifies timing closure and reduces design cost. The 176-TQFP (24x24) gull-wing package supports straightforward reflow assembly and inspection on standard SMT lines.
Typical applications include industrial control glue logic, telecommunications line-card interface logic, legacy ASIC redesigns, and avionics-adjacent commercial systems where one-time programming and instant power-up are required.
A key design consideration: because antifuse devices are one-time programmable, verify the netlist thoroughly in simulation and, where possible, on the pin-compatible SX-A (A54SX16A) prototyping device before committing production units.

일반적인 애플리케이션
A54SX16-TQG176 적합 용도: 6 애플리케이션s: Industrial Control Glue Logic, Telecommunications Line Cards, Legacy ASIC Redesign and Bridging, Test and Measurement Equipment, Avionics-Adjacent Commercial Systems, Security and Surveillance System Controllers.
Industrial Control Glue Logic
The A54SX16-TQG176 consolidates address decoders, bus transceivers, state machines, and interface adapters that would otherwise occupy multiple 74-series devices in PLCs, motor controllers, and factory automation boards. Its 24000 system gates and 147 user I/O provide ample capacity for mixed 5V and 3.3V interfaces via the dual 3V~3.6V and 4.75V~5.25V supply scheme. The antifuse fabric powers up instantly with no configuration latency, which matters for safety interlocks and machine-reset sequences that must assert correct logic levels immediately. Because the design is permanently programmed, field firmware updates are impossible - reserve this part for logic that is stable and validated.

Telecommunications Line Cards
In telecom line-card designs, the A54SX16-TQG176 implements framing logic, backplane interface multiplexing, and board-level glue functions between physical-layer devices and backplane controllers. The SX family sea-of-modules architecture gives deterministic routing delays, simplifying timing closure on synchronous backplane interfaces that run at hundreds of megahertz equivalent internal rates (family speeds of 240-320 MHz by speed grade). 5V-tolerant I/O eases integration with legacy 5V backplane signaling, and the 176-TQFP (24x24) package fits standard card assembly processes. Instant-on antifuse configuration avoids the link-down window that SRAM FPGAs incur while loading configuration from flash.
추천
Legacy ASIC Redesign and Bridging
The A54SX16-TQG176 is widely used to re-create discontinued ASICs or gate-array functions as a single-chip bridge on existing PCBs. Its 16000 gates and 924 cells approximate mid-1990s ASIC densities, and the one-time-programmable antifuse structure supports immediate power-up with no configuration device - matching the behavior of the original hard-wired ASIC. The dual 3.3V/5V supply interface reproduces legacy I-O signaling levels directly, and the 176-TQFP footprint can be laid out to match the replaced device. Designers should verify final timing with the Microchip Libero/Designer timing reports for the chosen speed grade before committing production programming.
추천
Test and Measurement Equipment
Bench instruments and automated test fixtures use the A54SX16-TQG176 for trigger generation, counter/timer logic, bus interfacing (GPIB-style parallel handshake logic), and control sequencers. The antifuse fabric's low static power and instant-on configuration let the instrument be measurement-ready within milliseconds of power application, and deterministic routing avoids run-to-run timing variation in trigger paths. The commercial 0C to +70C operating range covers typical bench and lab environments. With 147 I/O in the 176-TQFP (24x24) package, wide parallel stimulus buses to the device-under-test are easily accommodated without external fanout logic.
추천
Avionics-Adjacent Commercial Systems
Ground-support equipment and commercial subsystems for aerospace programs use the A54SX16-TQG176 where antifuse FPGAs are preferred for their immunity to configuration upset and no boot-time dependency. The one-time-programmable fabric cannot be corrupted in flight or on power cycling, and there is no configuration bitstream to capture - a security and reliability advantage over SRAM FPGAs. The standard commercial grade (0C to +70C) suits ground-based and sheltered equipment; for flight-temperature environments, migrate to the industrial-grade A54SX16P-2TQG176I, which shares the identical 176-TQFP footprint so the PCB design carries over unchanged.
추천
Security and Surveillance System Controllers
Video matrix switches, access-control panels, and DVR controller boards use the A54SX16-TQG176 for camera-interface multiplexing, keypad scan logic, and host bus bridging. The device's one-time programming means deployed units cannot be reconfigured by an attacker loading a malicious bitstream - unlike SRAM FPGAs that reload configuration at every power-up. 5V-compatible I/O directly drives legacy alarm-loop and relay-driver circuitry from the 4.75V~5.25V rail, while core logic runs at 3.3V. The 176-TQFP (24x24) package supports cost-effective, reworkable assembly in medium-volume security product manufacturing.

설계 노트
The A54SX16-TQG176 is one-time programmable: once antifuses are blown, the configuration cannot be changed or read back for correction. Validate the complete design in simulation and, where practical, prototype on the pin-compatible SX-A family (A54SX16A) before programming production units. Always archive the programmed fusemap and use a checksum verification step after in-system or pre-reflow programming to detect incomplete programming operations.
The device requires two supply rails: 3V to 3.6V for core and I/O operation, and 4.75V to 5.25V for programming and 5V-interface functions. Sequence the 3.3V rail before or with the 5V rail and decouple each rail with at least 0.1uF ceramic per power pin plus bulk 10uF capacitance. Estimated: with antifuse fabric the static current is very low, so thermal design is dominated by I/O switching current - compute dynamic power as P = C x V^2 x f x toggling-rate for large 5V-tolerant buses.
The 176-TQFP (24x24 mm) has 0.5 mm pitch gull-wing leads. Use a standard solder-mask-defined TQFP-176 land pattern with 0.25-0.3 mm trace widths at the device, and add thermal vias under the center of the footprint tied to ground for heat spreading and signal reference. Keep length-matched routing on clock pins and read back the Microchip SX family datasheet pin table for dedicated programming pins that must remain accessible on the PCB.
