Key Features

• Logic Capacity — 24,000 system gates and 1,452 logic elements provide implementation capacity for medium-complexity control, glue-logic and interface functions.
• I/O and Packaging — 81 user I/Os in a 100-pin (TQFP) package; surface-mount mounting type suitable for compact board layouts.
• Nonvolatile, Single-Chip Architecture — SX-A family nonvolatile configuration removes external configuration memory requirements and simplifies power sequencing.
• Voltage Flexibility — Supported supply range from 2.25 V to 5.25 V and family-level configurable I/O options (including 5 V tolerance and mixed-voltage operation) for easy interfacing to varied logic families.
• Temperature and Qualification — Military-grade temperature rating with an operating range of -55 °C to +125 °C for demanding environments.
• System Performance and Timing — SX-A family performance metrics include up to 250 MHz system performance and deterministic, user-controllable timing for predictable system behavior.
• Test, Security and Diagnostics — Boundary-scan testing (IEEE 1149.1/JTAG) and family features such as secure programming (FuseLock™) and in-system diagnostic/verification capabilities.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Military & Aerospace Systems — Compact, military-temperature-rated FPGA for mission-critical control, signal routing and interface logic in rugged platforms.
• Industrial Controls — Deterministic timing and mixed-voltage I/O support for industrial automation, sensor aggregation and real-time control tasks.
• Secure Embedded Systems — Nonvolatile configuration and secure programming features suitable for applications that require in-field programmability with protection against reverse engineering.
• Interface and Bus Bridging — Flexible I/O voltage support and JTAG boundary-scan make the device well suited for implementing custom bus interfaces and protocol glue logic.

Unique Advantages
