A54SX32-PQG208I

The A54SX32-PQG208I is a member of the SX-A FPGA family offering a nonvolatile, single-chip FPGA solution optimized for industrial applications. It provides deterministic timing control and a mix of system-level features designed for mixed-voltage designs and in-system verification.

Built for embedded and system-level designs, this device targets applications that require up to 48,000 system gates, 2,880 logic elements and 174 user I/Os while operating over an industrial temperature range and a 3 V to 5.5 V supply window.

Key Features

• Core performance — Family-level performance indicators include up to 250 MHz system performance and 350 MHz internal performance for time-critical logic.
• Logic capacity — 48,000 system gates and 2,880 logic elements suitable for mid-density glue logic, control and interface functions.
• I/O and voltage support — 174 user 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; devices support mixed-voltage operation and 5 V input tolerance with 5 V drive strength.
• Nonvolatile single-chip solution — Device stores configuration on-chip for simplified system design and field deployment.
• Power and reliability — Hot-swap compliant I/Os and power-up/power-down friendly operation that requires no special sequencing of supply voltages.
• System integration and test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and support for in-system diagnostics and verification with Silicon Explorer II.
• Security and protection — Actel Secure Programming Technology with FuseLock to protect designs from reverse engineering.
• Packaging and environmental — Surface-mount 208-BFQFP package (supplier package: 208-PQFP, 28×28); RoHS compliant and rated for industrial temperature operation (−40 °C to 85 °C).
• Supply range — Operates from 3 V to 5.5 V to accommodate a wide set of system power rails.

Typical Applications

• PCI-based peripherals — Use in PCI-compliant interface logic and bridging applications leveraging the family’s 66 MHz PCI compliance and mixed-voltage I/O support.
• Industrial control — Industrial-grade temperature support (−40 °C to 85 °C) and hot-swap I/Os make the device suitable for control, monitoring and automation subsystems.
• Mixed-voltage glue logic — Ideal for board-level interface translation and glue logic where multiple I/O standards and 5 V tolerance are required.
• In-system programmable logic — Nonvolatile single-chip configuration and in-system diagnostics/verification enable field updates and on-board validation during development and deployment.

Unique Advantages

• Highly integrated mid-density FPGA: 48,000 system gates and 2,880 logic elements provide substantial implementation density for control, interface and signal-processing glue logic while reducing external component count.
• Flexible I/O for mixed-voltage systems: Configurable I/O standards and 5 V tolerance simplify integration with legacy and modern bus standards without external level shifters.
• Nonvolatile, field-ready configuration: Single-chip nonvolatile architecture eliminates external configuration memory and enables reliable start-up and in-field reprogramming.
• Design protection and testability: FuseLock secure programming and IEEE 1149.1 boundary-scan support help protect IP and streamline manufacturing test.
• Deterministic timing and full utilization: User-controllable timing and support for up to 100% resource utilization and pin locking aid predictable timing closure and efficient use of logic resources.
• Industrial temperature rating: Specified operation from −40 °C to 85 °C for deployment in industrial environments.
