• Nonvolatile Architecture  Nonvolatile single-chip FPGA architecture for instant-on and secure configuration retention.
• Power and I/O Robustness  Hot-swap compliant I/Os, power-up/power-down friendly behavior (no sequencing required for supply voltages), and configurable weak pull-up/pull-down on outputs at power-up.
• Package Options  Offered in a 144-pin thin quad flat pack (144-LQFP / listed supplier package 144-TQFP, 20×20) for board-level integration.
• Automotive Qualification & Temperature  Automotive-grade device with AEC-Q100 qualification and operating temperature range of -40 °C to 125 °C.
• System Test & Security  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and secure programming technology (FuseLock™) to help protect design IP.
• Timing & Control  Deterministic, user-controllable timing with individual output slew-rate control and in-system diagnostic/verification capability as provided by the SX-A family tools.
• Supply Voltage  Flexible supply range from 2.25 V to 5.25 V to accommodate mixed-voltage systems.

Typical Applications

• Automotive Control Systems  Use for vehicle electronic subsystems where AEC-Q100 qualification and –40 °C to 125 °C operation are required for reliable on-board logic and interface functions.
• PCI/Legacy Interface Bridging  Leverage the SX-A family’s 66 MHz PCI compliance and configurable I/O to implement on-board interface logic and bridging functions.
• System Test & Verification  Implement boundary-scan (IEEE 1149.1) and in-system diagnostics to improve manufacturing test coverage and field verification workflows.
• Hot-Swap or Multi-Supply Environments  Deploy where hot-swap capable I/Os and power-up/power-down friendly behavior simplify system power sequencing and board-level integration.

Unique Advantages

• Automotive-Grade Certification: AEC-Q100 qualification and wide operating temperature range support designs destined for demanding environments.
• Secure, Nonvolatile Configuration: Nonvolatile architecture combined with FuseLock™ secure programming protects IP and removes the need for external configuration memory.
• Flexible I/O and Voltage Range: Configurable I/O standards and a 2.25–5.25 V supply window enable easy integration into mixed-voltage systems.
• Deterministic Timing Control: User-controllable timing and individual slew-rate adjustment let designers tune performance and signal integrity for their topology.
• Board-Level Test and Diagnostics: Built-in boundary-scan and in-system diagnostic capabilities streamline production test and field validation efforts.
• Compact Package with Ample I/O: 113 user I/Os in a 144-pin TQFP/LQFP form factor balance integration density with routing simplicity on typical automotive and embedded PCBs.
