A54SX16P-PQ208I

The A54SX16P-PQ208I is a nonvolatile SX-A family FPGA in a 208-pin BFQFP package designed for industrial-temperature applications. It provides deterministic, user-controllable logic resources and configurable I/O suitable for mixed-voltage system interfaces.

With 1,452 logic elements and 24,000 system gates, this device targets embedded control, interface bridging and system-level logic functions where in-system programmability, I/O flexibility and industrial operating range are required.

Key Features

• Core Logic  1,452 logic elements and 24,000 system gates provide deterministic, user-controllable timing for glue logic, state machines and control functions.
• Performance  SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family specification).
• I/O Flexibility  175 user I/Os with configurable 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 (family-level features).
• Nonvolatile Single-Chip Configuration  Single-chip, nonvolatile architecture enables in-system configuration without external configuration memory (SX-A family characteristic).
• System and Test Support  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and unique in-system diagnostic/verification capability (Silicon Explorer II – family feature).
• Security  Actel FuseLock™ secure programming technology (family feature) prevents reverse engineering and protects design IP.
• Power and I/O Controls  Configurable weak pull-up or pull-down on I/O at power-up, and individual output slew-rate control for signal integrity management (family-level).
• Package and Environmental  208-BFQFP package case; supplier device package listed as 208-PQFP (28×28). RoHS compliant and rated for industrial temperature operation from -40 °C to +85 °C.
• Supply Voltage Range  Operates from 3 V to 5.5 V to accommodate a range of mixed-voltage system designs.
• Embedded Memory  Total RAM bits: 0 (no embedded RAM present in this device).

Typical Applications

• PCI and Interface Bridging  Implement bus interfacing, glue logic and protocol translation in systems using 3.3 V / 5 V PCI and related mixed-voltage interfaces.
• Industrial Control and Automation  Deterministic logic resources and industrial temperature rating make the device suitable for control, monitoring and I/O aggregation in industrial equipment.
• Field-Programmable System Functions  Nonvolatile single-chip configuration and in-system diagnostic capabilities support field-updatable logic for product feature updates and verification.
• Security-Sensitive Designs  FuseLock secure programming technology provides protection against reverse engineering for designs that require IP protection.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates the need for external configuration memory, simplifying BOM and board-level design.
• Mixed-voltage I/O with 5 V tolerance: Directly interfaces with 2.5 V, 3.3 V and 5 V domains, reducing level-shifter requirements in mixed-supply systems.
• Industrial temperature rating: Rated for -40 °C to +85 °C to meet typical industrial environmental requirements.
• Deterministic timing and high resource utilization: User-controllable timing and up to 100% resource utilization and pin locking (SX-A family capability) aid predictable system behavior and tight design packing.
• Integrated test and security features: IEEE 1149.1 boundary-scan and FuseLock technology provide production testability and design IP protection.
• RoHS compliant: Meets lead-free environmental requirements for modern electronics manufacturing.
