A54SX16P-1PQG208M Visão geral
A field-programmable gate array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks and interconnects that designers program to implement custom digital circuits. Within the programmable logic hierarchy, the FPGA sits above CPLDs in gate density and below ASSPs in integration; the SX family uses Actel's patented antifuse technology, which is one-time programmable (OTP) rather than SRAM-based, so the configuration is non-volatile, inherently secure, and immune to configuration readback or radiation-induced configuration upsets.
Key differentiating features of the A54SX16P include 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup time, and 0.25 ns clock skew, enabling full 66 MHz PCI single-chip solutions with 100% resource utilization and 100% pin locking. The 'P' suffix denotes the enhanced-performance speed grade family with 5V-tolerant I/O.
Architecturally, the SX family's sea-of-modules structure combines C-cells (combinational) and R-cells (sequential/register) in a fine-grained cluster, routed by an antifuse interconnect matrix. This fine-grained architecture simplifies timing closure because routing delays are short and predictable, and it supports dramatic power and cost reductions for performance-intensive applications compared with coarse-grained alternatives.
Typical applications include glue logic consolidation and CPLD/FPGA single-chip integration, 66 MHz PCI interface bridging, industrial control and instrumentation, military/aerospace legacy designs requiring non-volatile OTP fabric, and communications line cards where configuration security matters.
Design consideration: antifuse FPGAs are one-time programmable - verify your design thoroughly in simulation before programming parts, and budget for spare programmed devices since a design change requires a new device.

Aplicações típicas
A54SX16P-1PQG208M é adequado para 6 aplicaçãos: 66 MHz PCI Interface and Bridge Logic, CPLD and FPGA Single-Chip Consolidation, Industrial Control and Automation, High-Reliability and Legacy Defense Systems, Communications Line Cards, Test and Measurement Instrumentation.
66 MHz PCI Interface and Bridge Logic
The A54SX16P-1PQG208M is explicitly rated for 66 MHz PCI single-chip integration, with 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup time, and 0.25 ns clock skew per the 54SX family datasheet. These figures allow the fabric to meet PCI setup/hold budgets at full 66 MHz while running at 100% resource utilization with 100% pin locking - a rare combination that lets designers lock the pinout early and still close timing. In a typical bridge design, the FPGA sits between a host PCI bus and local peripheral buses, absorbing CPLD-style glue functions into the same die. Because the antifuse fabric is non-volatile, the bridge is active at power-up with zero configuration latency, which is essential for PCI enumeration. 5V-tolerant I/O further simplifies interfacing with legacy 5V PCI signaling environments.

CPLD and FPGA Single-Chip Consolidation
Microchip positions the SX family as a CPLD and FPGA integration single-chip solution: the fine-grained C-cell/R-cell architecture replicates the predictable, fast pin-to-pin behavior of CPLDs while providing 24K system gates of FPGA capacity. For boards historically combining a CPLD for decode/state machines with an FPGA for datapath logic, the A54SX16P-1PQG208M merges both functions into one 208-pin PQFP, cutting BOM count, board area, and assembly cost. The 0.1 ns input setup and 3.7 ns clock-to-out figures mean address decode and handshaking logic behaves like a fast SPLD, while the 924 modules handle datapath tasks. Non-volatile antifuse configuration eliminates the boot CPLD/flash commonly needed beside SRAM FPGAs, removing another chip from the consolidation equation.
Recomendado
Industrial Control and Automation
In factory automation and industrial control backplanes, the A54SX16P-1PQG208M provides deterministic, instantly-active logic without configuration boot time, which shortens system power-up sequences on production lines. The 3.3 V core with 5V-tolerant inputs directly bridges legacy 5V industrial sensor and actuator signaling to modern 3.3V logic domains, eliminating level-shifting glue. For harsh-floor deployments, the same-die industrial variant A54SX16P-1PQG208I offers the extended -40C to +85C temperature range on the identical 208-pin PQFP footprint, letting one PCB layout serve both commercial and industrial builds. The antifuse fabric's immunity to configuration upset also suits electrically noisy motor-control environments where SRAM FPGA configuration corruption is a reliability concern.
Recomendado
High-Reliability and Legacy Defense Systems
Actel antifuse FPGAs such as the A54SX16P-1PQG208M are widely deployed in defense and aerospace legacy platforms precisely because the OTP fabric cannot be read back, providing design security, and is inherently resistant to configuration memory upset compared with SRAM FPGAs. Many fielded boards were designed around the 208-pin PQFP SX family, and sustaining those platforms requires continued sourcing of the exact footprint. The sea-of-modules architecture's predictable timing also simplifies certification documentation because delays do not shift with routing congestion between builds - an antifuse device programmed once exhibits fixed interconnect characteristics. For obsolescence mitigation, the same-die industrial and faster -2 grade variants listed on this page maintain pin and footprint continuity for long-life programs.
Recomendado
Communications Line Cards
Telecom and datacom line cards use the A54SX16P-1PQG208M for framing, glue, and interconnect logic where configuration security and instant-on behavior matter. The 320 MHz internal performance headroom supports high-rate state machines and multiplexing functions at T1/E1-through-STS-class rates, while 175 user I/O provides enough pins to terminate multiple serial links, LEDs, and backplane signals from a single 208-pin PQFP. Because antifuse configuration is immune to soft errors in the configuration store, the line card does not require configuration integrity monitoring or reload circuitry, reducing design complexity. The 0.25 ns clock skew specification simplifies source-synchronous interface timing closure across the board's clock distribution.
Recomendado
Test and Measurement Instrumentation
Bench and rack instrumentation designs employ the A54SX16P-1PQG208M for timing generators, bus interfaces, and control logic where deterministic delay is more valuable than reprogrammability. The 0.1 ns input setup and 0.25 ns clock skew enable precise, repeatable trigger timing across units - important for calibration stability, since an antifuse device's interconnect delays are permanently fixed after programming and cannot drift with temperature-induced SRAM reconfiguration variability. The 24K system gate capacity accommodates counters, decoders, and protocol engines, while 5V-tolerant inputs interface directly with legacy instrument I/O standards. Production lines benefit from instant power-up: instruments are ready before the operator's self-test completes.

Notas de projeto
Antifuse devices are one-time programmable: once programmed, the A54SX16P-1PQG208M cannot be erased or reprogrammed. Complete RTL simulation, static timing analysis at the -1 speed grade, and gate-level verification before submitting parts to the Silicon Sculptor programmer. Budget scrap - a design change invalidates every programmed unit. Order engineering lots accordingly and keep the source constrained in Libero so production place-and-route results match your verified run.
The A54SX16P operates from a 3.3 V supply with 5V-tolerant input structures; do not drive outputs above 3.3 V. Decouple VCC and the programming-related supply pins (VPP/VCI, per the 54SX datasheet power section) with low-ESR ceramics placed within a few millimeters of the PQFP pins. Because antifuse routing is fixed, static power is dominated by I/O loading - estimate dissipation from your actual toggle rates and output loads rather than worst-case family tables.
The 208-pin PQFP has a 0.5 mm pin pitch with leads on four sides; use an oxide-clean solder-mask-defined land pattern and inspect for solder bridging on the fine pitch. Assign unused I/O as inputs with pull-up or tri-state with weak pull-up in Libero to avoid floating-node contention. Maintain controlled-impedance routing on the 66 MHz PCI bus group and keep clock traces short and matched - the 0.25 ns clock skew spec assumes a clean clock distribution.
Informações de conformidade
Compliance status not explicitly stated in captured distributor data. The 'G' suffix in PQG208 conventionally indicates Microchip's green/lead-free package, but official RoHS/REACH certificates must be confirmed on the Microchip product page before production release.
