Key Features

• Core Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance, with 48,000 system gates and 2,880 logic elements for mid-range logic integration.
• I/O Flexibility — 249 user I/Os with configurable support for multiple I/O standards and 5 V input tolerance and drive strength. Family-level I/O features include hot-swap compliant I/Os and configurable weak pull-up/pull-down at power-up.
• Nonvolatile Single-Chip Architecture — Nonvolatile configuration stores design on-chip, removing the need for external configuration memory.
• Voltage and Power — Device supply range is 2.25 V to 5.25 V and is power-up/power-down friendly without sequencing requirements for supply voltages.
• Security and Test — Family features include Actel Secure Programming Technology (FuseLock™) to protect IP, boundary-scan testing compliant with IEEE 1149.1 (JTAG), and in-system diagnostic capability via Silicon Explorer II.
• Package and Mounting — 484-ball FBGA package (484-FPBGA, 27 × 27) in a surface-mount form factor suitable for compact board designs.
• Commercial Temperature Grade — Rated for operation from 0 °C to 70 °C and supplied as a commercial-grade device.
• Standards and Interfaces — Family-level support includes 66 MHz PCI compliance and configurable I/O for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.

Typical Applications

• Embedded Control and Interface Bridging — High I/O count and mixed-voltage support enable bridging between different logic domains and peripheral interfaces in commercial embedded designs.
• PCI-Based Systems — 66 MHz PCI compliance and configurable I/O make this device suitable for commercial systems requiring PCI interfacing.
• Instrumentation and Test Equipment — Nonvolatile configuration, JTAG boundary-scan, and in-system diagnostics support development and verification workflows in commercial measurement products.
• Prototyping and In-System Verification — In-system diagnostic features and deterministic timing make the device useful for iterative design validation and prototyping of commercial electronic systems.

Unique Advantages

• High I/O Density: 249 user I/Os provide extensive external connectivity for complex system interfaces and sensor/converter arrays.
• Mixed-Voltage Flexibility: Supports a broad voltage range (2.25 V–5.25 V) and multiple I/O standards, simplifying integration with diverse peripherals.
• Nonvolatile Configuration: Single-chip nonvolatile architecture removes the need for external configuration memory and simplifies board-level BOM.
• Secure Programming and Testability: FuseLock™ secure programming, IEEE 1149.1 boundary-scan, and Silicon Explorer II diagnostics help protect IP and streamline production test.
• Compact Package: 484-ball fine-pitch BGA in a surface-mount package balances high pin count with a compact PCB footprint.
• RoHS Compliant: Device is RoHS compliant, supporting environmentally conscious designs.
