A54SX32A-CQ256M

The A54SX32A-CQ256M is a HiRel SX-A family field programmable gate array (FPGA) offered in a 256-pin ceramic CQFP package with tie bar. It delivers a military‑grade FPGA option with up to 48,000 system gates, 2,880 logic elements, and up to 228 user‑programmable I/O pins for space‑constrained, reliability‑focused embedded systems.

Designed for high‑reliability and military temperature environments, this device supports a wide supply range and deterministic timing characteristics to serve mission‑critical applications that require robust performance across −55°C to +125°C.

Key Features

• Core Capacity  Approximately 48,000 system gates and about 2,880 logic elements provide mid‑range FPGA logic density suitable for consolidation of control and processing functions.
• I/O and Packaging  Up to 228 user‑programmable I/O pins in a 256‑pin BFCQFP ceramic package with tie bar; supplier device package listed as 256‑CQFP (75×75 mm).
• Performance  Documented family performance includes system operation to 215 MHz (military temperature) and 5.3 ns clock‑to‑out pin‑to‑pin timing in the SX‑A family.
• Supply Voltage Flexibility  Operates across a broad supply range from 2.25 V to 5.25 V, enabling mixed‑voltage interfacing options where required by system design.
• Thermal and Environmental Rating  Qualified for military ambient operation with full testing across −55°C to +125°C and Class B level device flow as described for the family.
• On‑Chip Memory  No embedded RAM on the device (Total RAM Bits: 0), appropriate for designs that use external memory or require predictable, RAM‑free logic implementation.
• Mounting and Compliance  Surface mount device; RoHS compliant to meet environmental regulations.
• HiRel Family Features  Family features include secure programming options, in‑system diagnostic capability, and deterministic, user‑controllable timing (as described for the SX‑A series).

Typical Applications

• Military and Defense Systems  Suited for mission‑critical control and signal processing where military temperature qualification and ceramic packaging are required.
• Aerospace Avionics  Use in avionics subsystems that demand deterministic timing and a wide operating temperature range for reliable airborne operation.
• Secure Embedded Controllers  Applicable for secure, tamper‑resistant designs leveraging the SX‑A family’s secure programming features for intellectual property protection.
• High‑Reliability Instrumentation  Integration into test, measurement, and instrumentation equipment that requires QML/Class B production flow and full temperature testing.

Unique Advantages

• Military‑Grade Qualification: Built and tested for −55°C to +125°C operation and Class B device flows, supporting deployment in harsh environments.
• Deterministic Timing: SX‑A family timing characteristics (including low clock‑to‑out latency) help designers implement predictable, time‑critical logic functions.
• Flexible Voltage Operation: Wide supply range from 2.25 V to 5.25 V provides design flexibility for mixed‑voltage systems and legacy I/O interfacing.
• Ceramic CQFP Packaging: 256‑pin ceramic CQFP (with tie bar) offers a hermetic packaging option for reliability‑sensitive applications.
• High I/O Density: Up to 228 user‑programmable I/O pins enable rich peripheral and bus interfacing without board‑level multiplexing.
• RoHS Compliant: Meets environmental compliance requirements while maintaining HiRel characteristics.
