A54SX32A-1CQ256B

The A54SX32A-1CQ256B is a military-grade FPGA from the HiRel SX-A family by Microchip Technology, delivered in a 256‑lead ceramic CQFP package with tie bar for surface-mount assembly. It provides a deterministic, secure programmable logic solution optimized for mission-critical and high-reliability embedded designs.

Built around 48,000 system gates and approximately 2,880 logic elements, this device targets applications that require high-speed system performance, robust I/O flexibility and proven military temperature qualification.

Key Features

• Core Performance 48,000 system gates and 2,880 logic elements provide deterministic logic capacity. Specified family performance includes up to 215 MHz system performance and 5.3 ns clock‑to‑out at military temperature.
• Logic & Flip‑Flop Resources Dedicated flip‑flop resources referenced in the SX‑A family enable consistent, user‑controllable timing for synchronous designs.
• I/O and Interface Flexibility 203 user I/O pins (surface mount) with hot‑swap compliant I/Os and configurable I/O support for 3.3 V / 5 V PCI, LVTTL and TTL signaling modes as defined by the SX‑A family.
• Voltage and Power Wide supply range from 2.25 V to 5.25 V and power‑up/power‑down friendly operation (no sequencing required for supply voltages), enabling mixed‑voltage system integration.
• Package and Mounting 256‑BFCQFP with tie bar (supplier device package: 256‑CQFP, 75 × 75) in a surface‑mount form factor suitable for high‑reliability assemblies.
• Military Qualification & Temperature Range Military grade device with operating range −55 °C to +125 °C and family-level QML and MIL‑STD‑883 process flow and testing described in the datasheet.
• Security & Testability Actel Secure Programming Technology with FuseLock to protect against reverse engineering and design theft; boundary‑scan (IEEE 1149.1 JTAG) support for in‑system test and debug.
• Memory Device listing shows zero on‑chip RAM bits, focusing the device on dedicated logic and flip‑flop implementations.

Typical Applications

• Military & Aerospace Systems Deployed where MIL temperature performance and QML/MIL‑STD‑883 testing support are required for mission‑critical logic functions.
• PCI‑Based Subsystems Suitable for implementing PCI interface logic and bridge functions with 3.3 V / 5 V PCI support and 5 V input tolerance documented at the family level.
• Secure, Embedded Control Used for secure programmable logic blocks where FuseLock programming and deterministic timing are important for protecting IP and ensuring predictable behavior.
• High‑Reliability Instrumentation Ideal for control, timing, and glue‑logic in instrumentation that requires ceramic packaging, wide supply range and extended temperature operation.

Unique Advantages

• Military‑grade qualification: The device is specified for −55 °C to +125 °C operation and follows MIL‑STD‑883 product flow and testing, supporting high‑reliability deployments.
• Deterministic timing: Family-level timing metrics such as 5.3 ns clock‑to‑out and predictable internal timing simplify timing closure for synchronous designs.
• Secure programming: FuseLock secure programming capability helps protect design IP from reverse engineering and unauthorized access.
• Flexible I/O and voltage tolerance: Wide supply range (2.25 V–5.25 V) and configurable I/O modes support mixed‑voltage system integration and PCI signaling needs.
• Proven ceramic packaging: 256‑lead ceramic CQFP with tie bar offers a rugged form factor suited to harsh environment assemblies and board‑level reliability.
• Power sequencing immunity: Power‑up/power‑down friendly operation reduces constraints during system power transitions and simplifies board power design.
