• User I/O and Packaging — 81 user I/Os in a 100‑pin LQFP/TQFP (14×14) surface-mount package; package case listed as 100‑LQFP with supplier package 100‑TQFP (14×14).
• Voltage Flexibility — Operates from 2.25 V to 5.25 V and supports mixed-voltage I/O modes referenced in the SX-A family, enabling interfacing with 2.5 V, 3.3 V and 5 V logic domains.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as specified for the family.
• Industrial Temperature Grade — Rated for operation from −40 °C to +85 °C for industrial applications.
• System & Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capabilities available within the SX-A family.
• Secure Programming — Family-level secure programming (FuseLock) technology to protect designs from reverse engineering.
• RoHS Compliance — Device is RoHS compliant.

Typical Applications

• PCI and legacy interface systems — Suitable for PCI-compliant interfaces and mixed-voltage card-level logic where 3.3 V / 5 V I/O compatibility is required.
• Industrial control & automation — Industrial temperature rating and robust I/O options make this FPGA suitable for motor control interfaces, sensor aggregation, and machine control logic.
• Board bring-up and manufacturing test — Boundary-scan (IEEE 1149.1) support and in-system diagnostics assist board-level testing and bring-up workflows.
• Secure embedded systems — Devices requiring protection of intellectual property can leverage the family’s secure programming (FuseLock) capability.

Unique Advantages

• Nonvolatile single-chip solution: Eliminates the need for external configuration memory while preserving in-system programmability.
• Mixed-voltage interfacing: Wide supply and I/O flexibility (2.25 V–5.25 V) simplifies interfacing across 2.5 V, 3.3 V and 5 V domains and reduces level-shifting components.
• Industrial-grade operation: −40 °C to +85 °C rating supports deployment in temperature-challenging environments.
• Secure design protection: FuseLock secure programming helps safeguard designs against reverse engineering and unauthorized copying.
• Compact packaging with ample I/O: 100‑pin LQFP/TQFP surface-mount package balances board space and connectivity with 81 user I/Os.
• Testability and verification: Boundary-scan (JTAG) and in-system diagnostic capabilities streamline production test and field diagnostics.
