Key Features

• Core performance — Series-level performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as specified for the SX-A family.
• Logic capacity — Approximately 24,000 system gates implemented across 1,452 logic elements, enabling medium-density logic integration on a single-chip FPGA.
• I/O density and flexibility — 175 user I/O pins (including clock buffers) with configurable I/O support for multiple voltage standards and 5 V input tolerance and drive characteristics as documented for the SX-A family.
• Power and voltage support — Operates from 3 V to 5.5 V supply rails and is power-up/power-down friendly with no sequencing required for supply voltages (series-level behavior).
• Security and testability — Includes Actel Secure Programming Technology (FuseLock™) and series-level support for boundary-scan (IEEE 1149.1/JTAG) and in-system diagnostic/verification capabilities.
• Package and mounting — 208-pin BFQFP package case; supplier device package listed as 208-PQFP (28×28). Surface mount mounting type.
• Industrial temperature grade — Rated for operation from −40 °C to +85 °C.
• RoHS compliant — Device meets RoHS requirements.
• Resource utilization and timing control — Series-level features include deterministic, user-controllable timing, individual output slew rate control, configurable weak pull-up/pull-down at power-up, and support for up to 100% resource utilization and 100% pin locking.

Typical Applications

• Industrial control — Industrial-grade temperature rating and wide supply voltage support make this device suitable for control logic, I/O aggregation and timing-critical tasks in industrial equipment.
• Mixed-voltage interface bridging — Configurable I/O voltage support and 5 V input tolerance enable the device to bridge and interface between 2.5 V, 3.3 V and 5 V logic domains.
• PCI and legacy bus systems — Series-level PCI compliance (66 MHz) supports implementation of interface logic for PCI-based subsystems.
• Secure, in-system programmable logic — Nonvolatile single-chip configuration and FuseLock™ secure programming support designs that require in-field programmability with protection against reverse engineering.

Unique Advantages

• Nonvolatile single-chip solution: Eliminates the need for external configuration memory by providing single-chip, nonvolatile configuration for simpler system design.
• Wide supply range: 3 V to 5.5 V operation lets the device be used in a broad set of mixed-voltage environments without extensive power-system changes.
• Industrial-grade operation: −40 °C to +85 °C rating supports deployment in industrial environments where temperature resilience is required.
• Flexible I/O and voltage compatibility: Configurable I/O standards and 5 V tolerance enable direct interfacing to diverse peripheral sets and legacy logic levels.
• Built-in test and security features: JTAG boundary-scan, in-system diagnostic capability and FuseLock™ protect design integrity and simplify validation and production testing.
• Compact, surface-mount package: 208-pin BFQFP/PQFP package provides a high pin count in a standard surface-mount form factor for space-constrained PCBs.
