A54SX16A-PQG208I

The A54SX16A-PQG208I is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It delivers 24,000 system gates with 1,452 logic elements and up to 175 user I/Os in a 208-pin package, providing reprogrammable logic and flexible I/O for embedded and industrial designs.

Designed for mixed-voltage systems and industrial-temperature operation, this surface-mount FPGA supports a wide supply range (2.25 V to 5.25 V) and operates from –40 °C to 85 °C, making it suitable for PCI-based systems, I/O-intensive controllers, and applications that require secure, in-system programmable logic.

Key Features

• Core Capacity  24,000 system gates and 1,452 logic elements provide programmable logic density for mid-range control, glue-logic, and interface functions.
• User I/O  Up to 175 user-programmable I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance  Family performance targets include system and internal operating frequencies suitable for timing-critical designs (family data lists 250 MHz system and 350 MHz internal performance).
• Nonvolatile Single-Chip Solution  Device retains configuration without external memory, simplifying board-level design and eliminating external configuration components.
• Power and I/O Robustness  Hot-swap compliant I/Os and power-up/power-down friendly behavior (no supply sequencing required) for reliable integration into live systems.
• Security and Test  Actel Secure Programming Technology with FuseLock™ prevents reverse engineering and supports boundary-scan testing compliant with IEEE 1149.1 (JTAG) for board-level testability.
• Package and Mounting  208-BFQFP package case; supplier device package listed as 208-PQFP (28×28). Surface-mount mounting type suitable for standard PCB assembly.
• Environmental and Supply  Voltage supply range 2.25 V to 5.25 V, operating temperature –40 °C to 85 °C, and RoHS compliant.
• Timing and Control  Deterministic, user-controllable timing features, individual output slew-rate control, and design diagnostic capability for predictable system behavior and in-system verification.

Typical Applications

• PCI and Interface Bridges  Use in 66 MHz PCI-compliant systems and I/O bridging where flexible, mixed-voltage I/O and PCI signaling support are required.
• Industrial Control and Automation  Reprogrammable logic for motor control, PLC interfacing, and real-time control tasks that benefit from nonvolatile configuration and industrial temperature range.
• System Glue Logic and Protocol Conversion  Mid-density logic integration for consolidating discrete components, implementing protocol translation, or adding custom logic functions.
• In-System Diagnostics and Verification  Built-in diagnostic capabilities and JTAG boundary-scan support for in-system verification and fault isolation during development and production test.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates the need for external configuration memory and simplifies board design.
• Wide supply and mixed-voltage I/O: 2.25 V–5.25 V supply range and multi-standard I/O support reduce the need for level translators and simplify integration with legacy and modern interfaces.
• Industrial temperature rating: Specified operation from –40 °C to 85 °C for reliable field deployment in industrial environments.
• Secure programming and testability: FuseLock security and IEEE 1149.1 boundary-scan support help protect IP and streamline production test.
• Predictable timing control: Deterministic timing features and individual slew-rate control aid in meeting tight system timing and signal integrity requirements.
