A54SX16P-1PQG208I 概述
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks (CLBs) and programmable interconnects that engineers configure in the field to implement custom digital logic. Within the programmable logic hierarchy, the device sits as FPGA -> programmable logic device -> digital IC, occupying the mid-density slot of the SX family below the SX32 and above the SX08.
Key features include a sea-of-modules architecture enabling 100% resource utilization with 100% pin locking, 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup time, and 0.25 ns clock skew. The device supports 66 MHz PCI single-chip integration and operates from a 3.3V supply with 5.0V-tolerant I/O (P version), simplifying interfacing with legacy 5V logic.
Technically, the antifuse programming technology is one-time programmable (OTP): configuration is permanent, power-on instant, and inherently resistant to configuration bit-stream corruption - a major reliability advantage over SRAM FPGAs in harsh environments, at the cost of no re-programmability. The sister A54SX16P-P1PQG208I variant is documented with 1452 CLBs, 3.0V to 3.6V supply, and 0.8 ns combinatorial CLB delay.
Typical applications include glueless PCI bus interfaces, industrial control and automation logic, aerospace/defense trusted logic (antifuse), communications line cards, and migration of multi-chip CPLD/gate-array designs into a single chip.
Design consideration: because the part is OTP, fully verify your design in simulation before committing hardware; pin locking is guaranteed at full resource utilization, but there is no design-change latitude after programming.

典型应用
A54SX16P-1PQG208I 适用于 6 应用s: 66 MHz PCI Bus Interface, Industrial Control and Automation, Aerospace and Defense Trusted Logic, Gate Array and Multi-CPLD Design Migration, Communications Line Cards and Backplane Logic, Test and Measurement Instrumentation.
66 MHz PCI Bus Interface
The SX family explicitly targets 66 MHz PCI, CPLD and FPGA integration as a single-chip solution. The A54SX16P-1PQG208I meets PCI timing with 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup, and 0.25 ns clock skew, allowing the entire PCI state machine and target/initiator logic to fit in one antifuse device with 100% pin locking. The 5.0V-tolerant I/O of the P version interfaces directly with 5V PCI signaling environments without external level shifting, reducing BOM cost. Because configuration is non-volatile antifuse, the PCI interface is active within microseconds of power-up - a requirement of some PCI specification timeout windows that SRAM FPGAs struggle to meet without a configuration PROM.
推荐
Industrial Control and Automation
In factory automation, motor control sequencing, and PLC I/O subsystems, the A54SX16P-1PQG208I consolidates dispersed 22V10-class CPLDs and gate arrays into a single 24K-gate device, cutting board area and power consumption. The industrial -40C to +85C rating of the I-suffix part covers unconditioned control cabinets, while 3.3V operation with 5.0V-tolerant I/O bridges mixed 5V sensor/relay logic with modern 3.3V controllers. Antifuse one-time programming eliminates configuration corruption from noisy industrial power events, and 175 user I/O absorbs large parallel signal counts typical of backplane and field-wiring interfaces.
推荐
Aerospace and Defense Trusted Logic
Actel antifuse FPGAs have a long heritage in defense electronics because the one-time-programmable fabric leaves no configuration bitstream in memory to corrupt under radiation or attack, and the metal-to-metal antifuse interconnect is inherently more SEU-tolerant than SRAM configuration cells. The A54SX16P-1PQG208I implements mission glue logic, bus bridges, and trusted interface functions at up to 320 MHz internal performance. For programs extending beyond the SX family EOL, Microchip's RTAX radiation-t hardened family (e.g., RTAX1000SL, RTAX2000S) continues this architecture lineage with the same design methodology in Libero.
推荐
Gate Array and Multi-CPLD Design Migration
The SX sea-of-modules architecture was designed to simplify migration of gate-array prototypes and multi-chip CPLD clusters into one programmable device, dramatically reducing design cost, power, and time to market. With 100% resource utilization guaranteed at 100% pin locking, engineers can route late pin changes without re-spinning the board - a key advantage over hard gate arrays that require mask changes. The 16,000 usable gates and 1452 CLBs of the SX16P absorb counters, state machines, address decoders, and bus logic that previously occupied several CPLDs, shrinking inventory and improving reliability through reduced interconnect.
推荐
Communications Line Cards and Backplane Logic
Telecom and datacom line cards historically used the SX16P for backplane address decoding, framing glue logic, and 5V-tolerant legacy bus interfacing. The 320 MHz internal performance and sub-ns setup times support high-throughput datapaths, while 175 user I/O handles the wide parallel buses of CompactPCI, VME, and proprietary backplanes. Instant-on antifuse configuration ensures the card participates in backplane arbitration immediately at power-up. Mixed 3.3V core / 5V-tolerant I/O removes level-shifter networks between legacy line-card ASICs and newer 3.3V processors.
推荐
Test and Measurement Instrumentation
Bench instruments and ATE modules use the A54SX16P-1PQG208I for timing generators, trigger logic, and measurement sequencers where the 0.25 ns clock skew and 320 MHz fabric support precise event timing. Antifuse determinism gives repeatable timing behavior unit-to-unit - valuable in calibrated instruments - and the one-time-programmed configuration cannot be altered in the field, protecting instrument firmware integrity. Instant-on operation lets the instrument be measurement-ready within microseconds of power application, and the industrial temperature range supports rack-level thermal environments.

设计说明
The A54SX16P-1PQG208I is one-time programmable antifuse silicon - there is no erase or rework path. Complete full functional simulation, timing closure in Microchip Designer (formerly Actel Designer), and a board-level bring-up plan before submitting the device to programming. Verify your design against the -1 speed grade timing files at worst-case industrial corners (-40C to +85C, 3.0V), not just typical conditions. Last-minute pin changes are survivable thanks to 100% pin locking, but logic changes are not.
The device operates from a single 3.3V rail (3.0V to 3.6V). Decouple each of the VDD/VSS pin pairs on the 208-pin PQFP with 0.1 uF ceramic capacitors placed within 3 mm of the pins, plus bulk 10 uF at the board level. Note that antifuse FPGAs draw a small static programming-related leakage at power-up but no configuration current from an external PROM - total supply budgeting is simpler than SRAM FPGAs. Confirm per-pin current allocation using the SX family datasheet I/O DC characteristics before driving heavy external loads.
The 208-pin PQFP has 0.5 mm pitch gull-wing leads; use the JEDEC-style footprint from the Microchip package outline drawing and a no-clean or water-wash soldering profile compatible with PQFP lead coplanarity. Route 66 MHz PCI traces with controlled impedance (approx. 50-65 ohm single-ended) and length-match within 1.5 ns group delay per the PCI specification. Because the part is EOL, consider laying out a slightly larger footprint that also accepts a daughter-card adapter for a future flash-FPGA migration path.
Estimated: at 24K gates with moderate toggle rates, typical core power for an SX16P is on the order of hundreds of milliwatts; verify against the SX family power calculator using your actual toggle-rate data. The exposed 208-lead PQFP relies on PCB copper for heat spreading - a 2 oz copper ground plane provides adequate theta-JA for industrial ambient up to +85C at expected power levels. No heatsink is normally required; confirm with a thermal simulation for high-utilization, high-frequency designs.
