A54SX32A-CQ84M

The A54SX32A-CQ84M is a military-grade SX‑A family FPGA from Microchip Technology, offered in an 84-pin ceramic CQFP with exposed pad and tie bar for surface-mount assembly. It delivers deterministic, user-configurable logic resources and I/O flexibility for systems that require high reliability across extreme temperature ranges.

With support for mixed 2.5 V / 3.3 V / 5 V operation and wide supply tolerance, this device is targeted at defense, aerospace and other high-reliability applications that demand secure programmable logic, QML-level qualification, and proven performance under MIL temperature conditions.

Key Features

• Logic Capacity – 48,000 system gates across approximately 2,880 logic elements, providing predictable resource allocation for medium-complexity designs.
• User I/O and Packaging – 69 user I/O pins in an 84‑pin CQFP (42×42) package with exposed pad and tie bar; surface-mount mounting for board-level integration.
• Performance – Up to 215 MHz system performance and 5.3 ns clock‑to‑out (pin‑to‑pin) at military temperature grades, with documented internal performance characteristics.
• Voltage Range – Flexible supply support from 2.25 V to 5.25 V enabling mixed-voltage system interfacing without complex voltage sequencing.
• Military‑Grade Reliability – Qualified for military temperature operation from −55 °C to +125 °C and offered in a QML/Class B flow with MIL-STD-883 screening.
• Secure Programming – Actel Secure Programming Technology (FuseLock) to help protect design IP and prevent reverse engineering.
• System and Test Support – Boundary-scan testing (IEEE 1149.1 / JTAG) and features such as hot‑swap compliant I/Os and power‑up/power‑down friendly behavior to simplify system bring-up and testing.
• Low-Power and Deterministic Timing – Designed for very low power consumption with user-controllable, deterministic timing suitable for time‑sensitive embedded systems.
• RoHS Compliant – Meets RoHS environmental requirements for lead‑free assembly processes.

Typical Applications

• Defense Electronics – Deploys in mission-critical subsystems requiring QML qualification and full military temperature operation for reliable field performance.
• Aerospace Systems – Useful for avionics and flight‑critical control logic where deterministic timing and wide temperature tolerance are essential.
• Secure Embedded Systems – Protects intellectual property and enables secure fielded designs with integrated FuseLock programming technology.
• System Integration and I/O Bridging – Implements custom interface logic and mixed-voltage I/O configurations in compact surface-mount packages.

Unique Advantages

• Military‑Grade Screening: Fabricated and delivered with MIL-STD-883 Class B screening and tested across −55 °C to +125 °C for predictable behavior in harsh environments.
• Secure Device Programming: Includes FuseLock secure programming to reduce risk of reverse engineering and protect design IP in deployed systems.
• Flexible Voltage Support: Operates across 2.25 V–5.25 V supplies and supports mixed 2.5 V/3.3 V/5 V interfacing, reducing the need for level‑shifters.
• Deterministic Performance: Documented clock‑to‑out and internal performance figures support designs that require tight timing control and predictable latency.
• Testability and Integration: Boundary‑scan (JTAG) support, hot‑swap compliant I/Os, and power‑up/down friendly behavior simplify manufacturing test and system integration.
• Compact, Surface‑Mount Ceramic Package: 84‑pin CQFP with exposed pad and tie bar (42×42) provides a compact footprint with robust thermal and mechanical features for high-reliability boards.
