A54SX32-1CQ208 - 48K Gate SX FPGA, 208-CQFP | Microchip
MPN： A54SX32-1CQ208 ✗ 停產A54SX32-1CQ208 概覽
An FPGA is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable interconnects, allowing designers to implement custom digital circuits after manufacturing. FPGAs sit within the broader hierarchy of programmable logic ICs, sitting above CPLDs in density and below ASICs in volume cost, and are a cornerstone of modern digital system design.
Key features of the A54SX32-1CQ208 include 2880 configurable logic modules in a sea-of-modules architecture, a 0.35 um CMOS process, and pin-to-pin family migration options across the SX and SX-A families. The sea-of-modules architecture simplifies design timing closure, reduces design cost and power consumption, and shortens time-to-market for performance-intensive applications.
Architecturally, the SX family uses a two-module fabric (sequential and combinational modules) that yields high gate utilization and predictable routing delays. The ceramic CQFP package with tie bar provides excellent mechanical reliability and thermal performance, making it suitable for harsh-environment and long-lifecycle systems.
Typical applications include aerospace and defense control logic, industrial automation controllers, communications infrastructure glue logic and protocol bridging, and test and measurement equipment where one-time-programmable antifuse reliability is valued.
Design consideration: this part is a legacy one-time-programmable (antifuse) FPGA and is RoHS non-compliant (contains lead per the ceramic package construction), so verify regulatory exemptions or consider newer family members for new designs.

典型應用
A54SX32-1CQ208 適用於 6 應用s: Aerospace and Defense Control Logic, Industrial Automation Controllers, Communications Infrastructure, Test and Measurement Equipment, Avionics and Legacy System Sustainment, Medical Device Control Electronics.
Aerospace and Defense Control Logic
The A54SX32-1CQ208 fits aerospace and defense control applications because its one-time-programmable antifuse fabric is immune to configuration upsets, and the ceramic 208-pin BFCQFP with tie bar provides hermetic, mechanically robust packaging suited to vibration and thermal cycling. With 48,000 gates, 2880 logic modules, and 174 user I/O, it implements sequencers, bus interfaces, and telemetry formatting at up to 240 MHz. Its dual-rail operation (3.3 V core, 5 V I/O) eases integration with legacy 5 V backplanes. The OTP nature also prevents bitstream extraction, an inherent security advantage over SRAM FPGAs in defense programs.
推薦
Industrial Automation Controllers
In industrial automation, the A54SX32-1CQ208 serves as deterministic glue logic, motor-control sequencers, and sensor-interface aggregation on PLC and drive boards. The 5 V-tolerant I/O bank (4.75 V to 5.25 V supply) connects directly to legacy industrial signaling, while the 3.3 V core keeps dynamic power manageable across 2880 logic modules. The one-time-programmable fabric removes configuration-storage failure modes common on factory-floor equipment, and the ceramic CQFP withstands the wider temperature swings of electrical cabinets. Its 240 MHz family performance ceiling comfortably covers counter, encoder, and interlock timing functions.
推薦
Communications Infrastructure
The A54SX32-1CQ208 integrates protocol bridging, backplane arbitration, and line-card glue logic in telecom and datacom equipment. With 48,000 system gates and up to 240 MHz operation in the 0.35 um CMOS process, it consolidates discrete PAL/GAL devices into one chip, reducing BOM cost and board area. The 174 user I/O support wide parallel data paths typical of T1/E1 and legacy backplane interfaces, and 5 V-compatible I/O eases mixing with older line-card circuitry. The sea-of-modules architecture delivers predictable routing delays, simplifying timing closure for synchronous framer interfaces.
推薦
Test and Measurement Equipment
Bench and automated test instruments use the A54SX32-1CQ208 for timing generators, pattern capture, and instrument bus interfacing. The antifuse fabric's deterministic delays support precisely timed stimulus generation, while 2880 logic modules and 174 I/O accommodate channel-dense pattern engines. The ceramic CQFP's thermal robustness handles continuous bench operation, and the dual 3.3 V core / 5 V I/O rails interface directly with TTL-level test fixtures. Because the configuration is burned in once, instruments power up instantly with no configuration load time - a measurable benefit for automated test throughput.
推薦
Avionics and Legacy System Sustainment
For avionics upgrades and legacy fleet sustainment, the A54SX32-1CQ208 lets engineers preserve proven, qualified RTL while replacing scarce or discontinued support components. Its one-time-programmable fabric eliminates configuration-device single points of failure in flight hardware, and the hermetic ceramic 208-pin CQFP with tie bar matches the package constructions commonly qualified in airborne systems. The dual-rail 3.3 V/5 V architecture integrates with both legacy 5 V avionics buses and modern 3.3 V processing sections. The CQ208M military-screened sibling extends operation across the full military temperature range.
推薦
Medical Device Control Electronics
Medical diagnostic and therapy equipment benefits from the A54SX32-1CQ208's fixed, verified logic: once programmed, the antifuse configuration cannot be corrupted by noise, software faults, or radiation-like events, supporting deterministic safety behavior in pump controllers and imaging subsystem sequencing. The 48,000-gate capacity handles interface logic, watchdog, and interlock functions, while 174 I/O connect to sensors, actuators, and front panels. The 5 V-tolerant I/O simplifies integration with established medical-bus transceivers. Designers should note the RoHS non-compliance and confirm applicable exemptions for legacy medical platforms.

主要差異化特點
- Hermetic ceramic CQFP package with tie bar (對比A54SX32-PQG208M)
- Commercial screening option within same footprint (對比A54SX32-1CQ208M)
- One-time-programmable antifuse security (對比SRAM-based competitor FPGAs)
設計說明
The A54SX32-1CQ208 requires two supply rails: 3.0 V to 3.6 V for the core and 4.75 V to 5.25 V for I/O buffers. Decouple each rail with bulk capacitance plus 0.1 uF ceramics placed at the package power pins. Estimated: with 2880 modules active at moderate utilization, core current is typically in the tens of mA range per the SX family datasheet power model - verify against your Libero/Designer power report rather than assuming. Ensure the 5 V I/O rail is present before applying 5 V-tolerant input signals to avoid latch-up stress.
This is a one-time-programmable antifuse FPGA: a design error after programming is unrecoverable on that device. Prototype on debug-friendly variants (or programming-service runs) before committing ceramic CQFP parts, which carry a significant unit cost. Also note the device is RoHS non-compliant (contains lead per distributor data) - confirm RoHS exemption 7 applicability for your market before production. Verify the exact screening suffix (commercial vs M) against program temperature requirements before substitution.
The 208-pin CQFP with tie bar has 0.5 mm lead pitch (per distributor Utmel listing) and requires careful solder-paste stencil design to prevent bridging on the fine-pitch perimeter leads. The tie bar must be soldered or mechanically anchored - leaving it floating creates a resonance point under vibration. Provide symmetrical fan-out around the package to minimize skew on wide parallel buses, and route the 5 V I/O bank with adequate spacing from the 3.3 V core domain to respect mixed-voltage creepage expectations.
合規資訊
Per digchip distributor data: RoHS Non-Compliant, Contains Lead - typical of legacy ceramic CQFP packaging. Verify RoHS lead-in-ceramic exemption applicability.
