This device is designed for applications that require deterministic logic resources and flexible mixed-voltage I/O. Key electrical and environmental parameters include a voltage supply range of 2.25 V to 5.25 V and a commercial operating temperature range of 0 °C to 70 °C. The device is RoHS compliant.

Key Features

• Logic Capacity  24,000 system gates and 1,452 logic elements provide a defined resource set for mid-density digital designs.
• I/O and Interface Flexibility  Up to 175 user I/Os with configurable support for mixed-voltage operation (2.5 V, 3.3 V, 5 V) and 5 V input tolerance and drive strength, simplifying interfacing with a range of peripheral devices and legacy buses.
• Nonvolatile, Single-Chip Configuration  On-chip, nonvolatile configuration removes the need for external configuration memory and supports power-up/power-down friendly behavior without supply-sequencing requirements.
• Performance Characteristics  SX-A family performance specifications include up to 250 MHz system performance and up to 350 MHz internal performance (family-level specification).
• Deterministic Timing & Debug  Deterministic, user-controllable timing and in-system diagnostic/verification capability (Silicon Explorer II) help with predictable timing closure and field diagnostics (family-level features).
• Test and Security  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering (family-level features).
• Package & Mounting  208-pin surface-mount quad-flat package (208-BFQFP / 208-PQFP, 28×28 mm footprint noted by supplier) for standard PCB assembly processes.
• Electrical & Environmental  Voltage supply range: 2.25 V to 5.25 V. Operating temperature: 0 °C to 70 °C. RoHS compliant.
• Embedded Memory  No on-chip RAM bits (Total RAM bits: 0), enabling designs that rely on logic and external memory resources.

Typical Applications

• Mixed-Voltage Interface Designs  Use the device to bridge or interface between 5 V and 3.3 V logic domains where 5 V tolerance and mixed-voltage support are required.
• PCI and Bus-Based Subsystems  Family-level PCI compliance and abundant I/Os make the device suitable for subsystem logic on boards implementing 66 MHz PCI-compatible interfaces.
• Embedded Control and Glue Logic  Mid-density gate count and plentiful I/Os enable integration of control functions, protocol translation, and glue logic to reduce external components.

Unique Advantages

• Highly Integrated Logic Resources: 24,000 system gates and 1,452 logic elements consolidate mid-density logic into a single package, reducing PCB area and BOM complexity.
• Nonvolatile Configuration: Built-in, single-chip nonvolatile configuration removes the need for external configuration PROMs, simplifying system power-up behavior.
• Flexible Mixed-Voltage I/O: Configurable I/O and 5 V tolerance enable direct interfacing with a wide range of peripherals and legacy interfaces without level shifters.
• Design Visibility and Test: Boundary-scan (IEEE 1149.1) and in-system diagnostics (Silicon Explorer II capability at the family level) help streamline manufacturing test and field troubleshooting.
• Security Options: FuseLock secure programming technology (family feature) provides a hardware-based option to protect intellectual property.
• Commercial Temperature and RoHS Compliance: Commercial-grade operating range (0 °C to 70 °C) and RoHS compliance support standard electronics production and regulatory requirements.
