A54SX32-CQ208B

The A54SX32-CQ208B is a military-grade, surface-mount FPGA in a 208-pin ceramic CQFP package with tie bar. As a HiRel SX-A family device, it combines a fixed-architecture FPGA fabric with features tailored for high-reliability, military-temperature applications.

This device delivers 48,000 system gates across approximately 2,880 logic elements, 1,080 dedicated flip-flops and 174 user I/Os, supporting mixed-voltage operation and wide operating temperatures for harsh-environment embedded systems.

Key Features

• Core Capacity — Approximately 48,000 system gates implemented as about 2,880 logic elements and 1,080 dedicated flip-flops for deterministic, user-defined logic.
• I/O and Interface Flexibility — 174 user-programmable I/Os with configurable support for mixed-voltage operation; I/O architecture supports 3.3 V and 5 V signaling as described for the SX-A family.
• Performance (Family-Level) — HiRel SX-A family performance characteristics include up to 215 MHz system performance and 5.3 ns clock-to-out pin-to-pin timing at military temperature grades (family datasheet values).
• Power and Voltage — Operates from 3 V to 5.5 V supply range; family-level features include power-up/power-down friendliness with no required sequencing.
• No Embedded SRAM — Total on-chip RAM bits reported as 0, making this device suitable for control and glue-logic functions that rely on flip-flops and combinatorial resources.
• Package & Mounting — Ceramic 208-BFCQFP with tie bar (supplier package listed as 208-CQFP, 75×75 mm footprint), surface-mount mounting type for PCB assembly.
• Environment & Reliability — Military grade with operating temperature range −55 °C to +125 °C; QML/Class B process and family-level hermetic packaging and screening flows are reflected in the HiRel SX-A datasheet.
• Security & Test — Family-level features include Actel Secure Programming Technology (FuseLock) and boundary-scan testing compliant with IEEE 1149.1 (JTAG) for in-system testability and IP protection.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• Military & Aerospace Systems — Control, glue logic and interface functions in systems that require operation across −55 °C to +125 °C and QML/Class B screening.
• High-Reliability Embedded Control — Deterministic logic and I/O control for mission-critical subsystems where ceramic packaging and military-grade screening are required.
• PCI & Mixed-Voltage Interfaces — Implementing interface logic and protocol bridging for 3.3 V/5 V PCI and mixed-voltage environments (family-level PCI compliance noted in datasheet).
• Secure, In-System Programmable Logic — Applications that benefit from in-field programmability combined with FuseLock security and IEEE 1149.1 boundary-scan support for diagnostics and test.

Unique Advantages

• Military-Grade Screening: Designed and screened for −55 °C to +125 °C operation and Class B/MIL-STD-883 flows per the HiRel SX-A family documentation, supporting deployment in harsh environments.
• Deterministic, Fixed-Architecture Logic: Approximately 2,880 logic elements and dedicated flip-flops enable predictable timing and resource utilization for control and interface functions.
• Mixed-Voltage I/O Support: I/O architecture supports 3.3 V and 5 V signaling, enabling direct interfacing with a wide range of legacy and modern logic levels.
• Ceramic CQFP Packaging: 208-pin ceramic package with tie bar provides a hermetic-capable form factor suitable for high-reliability assemblies and established military PCB processes.
• Security & Testability: Family-level FuseLock programming and IEEE 1149.1 boundary-scan support simplify secure deployment and in-system diagnostics.
• Wide Supply Range: 3 V to 5.5 V operating range gives flexibility for integration into systems with different supply domains.
