Overview of A54SX32A-CQ256B – SX-A Field Programmable Gate Array (FPGA) IC 203 256-BFCQFP with Tie Bar
The A54SX32A-CQ256B is a HiRel SX-A family FPGA supplied in a 256-pin ceramic CQFP package with tie bar. It delivers a military-grade, single-chip programmable logic solution with 48,000 system gates and 2,880 logic elements, targeted at high-reliability embedded systems and defense applications.
Designed for environments that demand wide temperature and voltage tolerance, this device combines deterministic timing characteristics and on-board security features to support robust, secure system designs.
Key Features
- Core & capacity — 48,000 system gates and 2,880 logic elements (cells) with 1,080 dedicated flip-flops, providing a compact, deterministic logic resource for complex control and signal-processing functions.
- Performance (series-level) — Series documentation cites up to 215 MHz system performance at military temperature, 5.3 ns clock-to-out (pin-to-pin) and up to 240 MHz internal performance; suitable for timing-critical subsystems.
- I/O & package — 203 user-programmable I/O pins on this part; supplied in a 256-BFCQFP package with tie bar (supplier package: 256-CQFP, 75 × 75 mm), surface-mount mounting for compact board designs.
- Power & voltage — Operates from 2.25 V to 5.25 V supply rails. Series-level documentation supports mixed 2.5 V / 3.3 V / 5 V operation with 5 V input tolerance, enabling flexible interfacing with legacy and modern peripherals.
- On-chip memory — This device reports 0 total on-chip RAM bits, suitable for designs that rely on distributed logic or external memory.
- Reliability & qualification — Military-grade device classification with operating temperature range –55°C to +125°C and production flow consistent with MIL-STD-883 screening as documented for the series.
- Security & in-system capability — Series-level features include Actel Secure Programming Technology with FuseLock to prevent reverse engineering, boundary-scan (IEEE 1149.1 JTAG) support, and in-system diagnostics referenced in the product documentation.
- Compliance — RoHS compliant.
Typical Applications
- Military and aerospace systems — Rugged, temperature-hardened programmable logic for mission-critical control and data-processing subsystems.
- Defense electronics — Secure, QML-aligned production flow and secure programming capabilities for protected designs and classified hardware.
- High-reliability embedded control — Deterministic timing and wide voltage tolerance for deterministic motor, actuator, or sensor interface control in harsh environments.
- Secure communications and hardware security — FuseLock secure programming and boundary-scan support for secure design deployment and field diagnostics.
Unique Advantages
- Military-grade qualification: Built and documented for MIL-STD-883 production screening and 100% military temperature testing (–55°C to +125°C), supporting high-reliability program requirements.
- Deterministic, timing-focused architecture: Series performance metrics and clock-to-out figures support designs that require predictable timing behavior.
- Wide voltage flexibility: 2.25 V–5.25 V supply range and series-level mixed-voltage operation permit interfacing with a broad range of system I/O standards.
- Integrated security features: Series-level FuseLock secure programming reduces risk of reverse engineering and protects intellectual property in deployed systems.
- Compact, high-density logic: 48,000 system gates and 2,880 logic elements provide substantial logic capacity in a single-chip solution to reduce BOM and simplify system architectures.
- Rugged packaging options: 256-pin ceramic CQFP with tie bar and surface-mount mounting suited to rugged, board-level integration.
