A54SX16P-PQG208

The A54SX16P-PQG208 is a nonvolatile SX-A family FPGA presented in a 208-pin BFQFP package, offering 24,000 system gates and 1,452 logic elements for mid-density programmable logic designs. With 175 user I/O pins and mixed-voltage I/O support, it is designed for applications requiring flexible interfacing across 3.3 V and 5 V domains.

This device targets embedded control, I/O bridging and interface-intensive designs where deterministic timing, secure configuration and broad I/O compatibility are important. It combines single-chip nonvolatile configuration and configurable I/O to simplify board-level integration.

Key Features

• Logic Capacity — 1,452 logic elements (combinatorial cells) and approximately 24,000 system gates to implement mid-density logic functions and state machines.
• User I/O — 175 user-programmable I/O pins supporting configurable I/O standards and 5 V input tolerance for legacy and mixed-voltage interfacing.
• Nonvolatile Single-Chip Configuration — SX-A family nonvolatile architecture provides single-chip configuration without external memory.
• Performance — Family-level published performance targets include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Mixed-Voltage Operation — Supports 2.5 V, 3.3 V and 5 V mixed-voltage operation with configurable I/O drive and input tolerance, enabling flexible board-level interfacing.
• Package and Mounting — Surface-mount 208-pin BFQFP (supplier 208-PQFP, 28 × 28 mm footprint) for compact PCB integration.
• Power and Supply — Wide voltage supply range from 3.0 V to 5.25 V to match system power rails.
• System Diagnostics and Test — Boundary-scan (IEEE 1149.1/JTAG) support and in-system diagnostic capabilities as provided by the SX-A family.
• Security — Family-level secure programming technology (FuseLock™) to protect configuration and prevent reverse engineering.
• Compliance — RoHS compliant and specified for commercial temperature operation (0 °C to 70 °C).

Typical Applications

• Interface Bridging and Bus Glue Logic — Use the device’s 175 I/Os and mixed-voltage support to translate and glue together legacy 5 V logic and modern 3.3 V peripherals.
• Embedded Control and State Machines — Deploy the 1,452 logic elements and deterministic timing for control logic, protocol handling and custom sequencers.
• PCI and Peripheral Interfaces — Family-level 66 MHz PCI compliance and configurable I/O make it suitable for mid-speed peripheral interfacing and legacy PCI bridging.
• In-System Programmable Prototyping — Nonvolatile, single-chip configuration and boundary-scan support facilitate iterative development and board-level testing.

Unique Advantages

• Single-Chip Nonvolatile Design: Eliminates the need for external configuration memory, reducing BOM and simplifying power-up behavior.
• Flexible I/O Compatibility: Configurable I/O standards and 5 V tolerance enable direct interfacing with a wide range of legacy and modern signals.
• Secure Configuration: FuseLock™ technology protects the programmed design against unauthorized readout and reverse engineering.
• Deterministic Performance: Published family performance (up to 250 MHz system, up to 350 MHz internal) supports timing-sensitive logic implementations.
• Comprehensive Testability: Boundary-scan (IEEE 1149.1) and in-system diagnostics simplify manufacturing test and field verification.
• RoHS-Compliant Packaging: Environmentally compliant package suited to commercial electronics production.
