• Nonvolatile Single-Chip Architecture — SX-A family nonvolatile single-chip solution simplifies system start-up and configuration management.
• Configurable Multi-Voltage I/O — Family-level support for 2.5 V, 3.3 V and 5 V mixed-voltage operation, including support described for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; devices support 5 V input tolerance and 5 V drive strength.
• Power and I/O Robustness — Hot-swap compliant I/Os and power-up/down friendly behavior (no sequencing required for supply voltages) simplify system power management.
• Voltage and Temperature Range — Operates from 2.25 V to 5.25 V and specified for industrial temperature range of −40 °C to 85 °C.
• Package and Mounting — 100-pin LQFP package case with surface-mount mounting type (supplier package listed as 100-TQFP, 14×14 mm).
• Design for Test and Security — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and family-level secure programming technology (FuseLock) to protect designs.
• Standards and Performance (Family) — SX-A family datasheet documents up to 250 MHz system performance and internal performance claims; family-level features include 66 MHz PCI compliance where applicable.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Deterministic programmable logic and industrial temperature rating make this FPGA suitable for control logic, signal conditioning and I/O consolidation in industrial automation equipment.
• Interface Bridging — Use the device to implement protocol conversion, bus bridging or custom interface glue logic where mixed-voltage I/O and 81 available I/Os are required.
• Embedded System Glue Logic — Integrate peripheral control, timing logic and custom state machines in compact embedded platforms using the device’s logic elements and nonvolatile configuration.
• PCI-Compatible Subsystems — Family-level 66 MHz PCI compliance supports legacy PCI interface implementations where stated by the system design.

Unique Advantages

• Nonvolatile Configuration: Eliminates external configuration memory and simplifies system start-up and maintenance.
• Mixed-Voltage Flexibility: I/O configurability across common voltage standards reduces the need for level shifters and minimizes BOM complexity.
