A54SX16P-PQG208I 개요
An FPGA (field programmable gate array) is a reprogrammable semiconductor device that implements digital logic through a matrix of configurable logic blocks and programmable interconnects. Within the programmable logic hierarchy, the FPGA sits above SPLDs and CPLDs, offering higher gate counts and register-rich architectures suitable for glue logic integration, bus interfacing, and state-machine control in embedded systems.
The SX family uses a sea-of-modules architecture built on a 0.35 um CMOS process. This register-dense fabric allows 100% resource utilization with 100% pin locking, simplifying timing closure and PCB design. The A54SX16P operates from a single 3.3V supply with 5V-tolerant I/O, easing integration into legacy 5V bus systems such as PCI-compliant designs.
Technically, the device provides fast pin-to-clock performance with low clock skew, enabling single-chip integration of functions that previously required multiple CPLDs or ASSPs. The 'P' variant of the SX family offers enhanced I/O capabilities, and the PQG208 industrial-grade suffix (I) guarantees operation across -40C to +85C, critical for industrial and communications equipment exposed to wide ambient swings.
Typical applications include industrial automation controllers, telecommunications line cards, test and measurement instrumentation, and military/aerospace legacy system sustainment, where the anti-fuse-class reliability of the SX architecture and 5V-tolerant I/O are decisive selection factors.
A key design consideration: as an antifuse/one-time-programmable class FPGA family, the SX series is programmed at programming stations rather than reconfigured in-system, so design iteration requires new programmed devices. Verify programming file compatibility with your programmer before procurement.

일반적인 애플리케이션
A54SX16P-PQG208I 적합 용도: 6 애플리케이션s: Industrial Automation Controllers, Telecommunications Line Cards, Test and Measurement Instrumentation, Aerospace and Defense Legacy Sustainment, Embedded Glue Logic and Bus Bridging, Security and Surveillance Control Logic.
Industrial Automation Controllers
The A54SX16P-PQG208I fits industrial PLC and motor-control supervisory logic because its industrial temperature grade (-40C to +85C) and 175 user I/O cover the many discrete and encoder interfaces typical of factory equipment. Operating at up to 240 MHz internal performance with 16K gates and 924 cells, it consolidates glue logic, interrupt controllers, and state machines that previously occupied multiple CPLDs, cutting BOM count and board area. The 5V-tolerant 3.3V I/O connects directly to legacy 24V-buffered, 5V-logic sensor front ends common in brownfield installations. As a one-time-programmable class device it also resists configuration corruption from noisy industrial power events, an advantage over SRAM FPGAs in electrically harsh environments.

Telecommunications Line Cards
Telecom line-card designs benefit from the A54SX16P-PQG208I's register-rich sea-of-modules architecture and 240 MHz internal speed, which support framing, timing, and backplane handshake logic at T1/E1-class rates. The 208-pin PQFP offers fine-pitch surface-mount assembly compatible with legacy telecom manufacturing flows, while 5V-tolerant I/O bridges older 5V backplane signaling with 3.3V core logic. With 100% pin locking, designers can fix card-to-card interface pinouts early and iterate internal logic without PCB respins - a decisive cost saver in long-lived telecom platforms requiring decade-scale sustainment.
추천
Test and Measurement Instrumentation
Bench and automated test instruments use the A54SX16P-PQG208I as a control FPGA for trigger sequencing, counter/timer channels, and instrument bus interfacing. The 175 user I/O drives front-panel indicators, relay arrays, and digitizer handshakes, while the 0.35 um CMOS SX fabric delivers deterministic, register-dense timing with low clock skew (sub-nanosecond class per family data). One-time programmability guarantees the instrument always powers up in a known configuration - valuable for calibration integrity. Its 3.3V supply with 5V tolerance simplifies mixed-voltage designs interfacing GPIB-era and modern logic simultaneously on one board.
추천
Aerospace and Defense Legacy Sustainment
Defense and avionics programs that standardized on Microsemi SX FPGAs in the 1990s and 2000s rely on the A54SX16P-PQG208I for obsolescence-mitigation builds. The industrial -40C to +85C grade and one-time-programmable, configuration-storage-free fabric eliminate configuration-readout concerns valued in high-reliability platforms. Because the RTAX radiation-tolerant family extends the same design methodology, teams can migrate designs forward when radiation tolerance is later required. Microchip's continued support of the SX line through Libero design tools and licensed programming stations sustains depot-level repair for fielded systems without board redesign.

Embedded Glue Logic and Bus Bridging
As a general glue-logic FPGA, the A54SX16P-PQG208I replaces dozens of 5V and 3.3V TTL/CMOS ASSPs: address decoders, wait-state generators, bus arbiters, and interrupts controllers. Nine hundred twenty-four cells with full pin locking let designers map microprocessor buses to peripherals at fixed pins, simplifying layout and signal integrity on two-to-four-layer boards. The 3.3V core with 5V-tolerant inputs directly bridges legacy 5V microprocessor systems to modern 3.3V peripherals without level shifters, reducing component count. At 240 MHz capability, even fast 66 MHz PCI-class timing targets referenced in family documentation are achievable single-chip.
추천
Security and Surveillance Control Logic
Video-surveillance and access-control equipment uses the A54SX16P-PQG208I to coordinate sensor polling, relay actuation, and camera-control protocol timing. Its 16K-gate capacity comfortably hosts UART/SPI aggregation, watchdog logic, and tamper-detection state machines, while 175 I/O connects alarm loops and lock drivers. The industrial temperature range suits outdoor cabinets and unconditioned enclosures, and one-time-programmable configuration ensures the controller resumes correct operation after power interruption - important for security uptime guarantees. Deterministic, processor-free logic also avoids software-vulnerability surfaces in hardened installations.

설계 노트
The A54SX16P runs from a single 3.3V rail. Decouple the 208-pin PQFP power pins with at least one 0.1 uF ceramic capacitor per pair of VDD pins placed within 3 mm of the pin, plus 10 uF bulk capacitance per supply domain. Because 5V-tolerant inputs still draw clamp-related current when driven above 3.3V, series-limit the 5V-sourced lines if source impedance is very low. Verify total supply current from your post-layout simulation, since SX static and dynamic current depends heavily on toggle rates in the 924-cell fabric.
At up to 240 MHz internal performance and fast pin-to-pin output timing on the SX16P, treat all outputs above roughly 50 MHz as controlled-impedance nets. Keep PQG208 fanout traces short, reference a solid ground plane, and use series termination (22-33 ohm) on long lines to control overshoot - the 0.35 um I/O has fast edges even at low toggle rates. Reserve ground pins adjacent to high-switching I/O banks and avoid routing clocks on the package periphery adjacent to noisy I/O groups.
SX devices are one-time-programmable class FPGAs: they cannot be reconfigured in-system like SRAM FPGAs. Budget for programmed-device lead time in production, and lock your pin assignments early (the family supports 100% utilization with 100% pin locking) because later pin changes force reprogramming all devices. Also confirm the exact speed-grade ordering code (-1/-2 vs standard) matches your timing sign-off - a base-grade part substituted for a -1 build will fail static timing at 320 MHz-class clocks.
Estimated: the 208-PQFP theta_JA is on the order of 40-60 C/W with a solid ground-plane copper pour (per typical PQFP-208 thermal data - confirm in the manufacturer datasheet package section). At a conservative 0.5 W internal dissipation in the 16K-gate fabric, junction rise above ambient is roughly 20-30 C, comfortably within the -40C to +85C industrial range for Ta up to about +55C. Compute your actual power from Libero power estimation before finalizing enclosure cooling.
