Key Features

• Capacity and Logic — 48,000 system gates and approximately 2,880 logic elements provide substantive logic density for glue logic, control, and mid-complexity designs.
• I/O and Voltage Flexibility — 174 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 and 5 V input tolerance.
• Performance — Family-level specifications include up to 250 MHz system performance and up to 350 MHz internal performance for time-critical logic paths.
• Nonvolatile Single-Chip Configuration — On-chip nonvolatile configuration removes the need for external bitstream memory and simplifies system startup; power-up/down friendly with no supply sequencing required.
• Security and Test — Actel Secure Programming Technology (FuseLock™) for protection against reverse engineering, plus IEEE 1149.1 JTAG boundary-scan for board-level testing and diagnostics.
• In-System Diagnostics — Supports in-system diagnostic and verification capabilities (Silicon Explorer II) to streamline bring-up and debugging.
• Package and Mounting — 208-pin BFQFP package (supplier device package: 208-PQFP, 28 × 28) in a surface-mount form factor for compact PCB designs.
• Power and Temperature — Wide supply range of 3 V to 5.25 V and commercial operating temperature range of 0 °C to 70 °C.
• Regulatory — RoHS compliant.
• Speed Grade — The –2 speed grade indicates approximately 25% faster performance than the standard speed grade for the SX-A family.
• Embedded Memory — No on-chip RAM bits; suitable for applications that utilize external memory or are optimized for minimal embedded RAM usage.

Typical Applications

• Commercial Embedded Systems — Implement control logic, protocol handling, and interface glue in compact commercial products that require configurable I/O and moderate logic density.
• PCI and Bus Interfaces — Use the device’s configurable I/O and PCI-compatible signaling for 3.3 V / 5 V PCI interfacing and bus bridging tasks.
• Security-Conscious Designs — Apply FuseLock™ programming to protect IP in products where design confidentiality is required.
• Test & Measurement Equipment — Leverage deterministic timing and JTAG boundary-scan for reliable instrument control and board-level testability.

Unique Advantages

• Deterministic, User-Controllable Timing: SX family timing architecture provides predictable timing behavior for designs requiring repeatable performance characteristics.
• Single-Chip Nonvolatile Configuration: Eliminates external configuration memory and simplifies system BOM and startup sequencing.
• Flexible Mixed-Voltage I/O: Configurable I/O standards and 5 V tolerance reduce or remove the need for external level translators in mixed-voltage systems.
• Design Protection: FuseLock™ secure programming helps prevent reverse engineering and protects IP in the field.
• Built-In Test and Debug Support: JTAG boundary-scan plus Silicon Explorer II diagnostics streamline bring-up, in-system verification, and fault isolation.
• RoHS Compliant Commercial Option: Meets RoHS requirements and is targeted for commercial-temperature applications (0 °C to 70 °C).
