Key Features

• Core Performance  Delivers 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 and 1,452 logic elements provide mid-level programmable logic resources for glue logic, control, and datapath functions.
• I/O Flexibility  81 user I/Os with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2; supports 5 V input tolerance and 5 V drive strength per SX-A family specifications.
• Mixed-Voltage Operation  Supports 2.5 V, 3.3 V, and 5 V mixed-voltage operation with power-up/power-down friendliness (no sequencing required for supply voltages).
• Nonvolatile Single-Chip Configuration  Single-chip, nonvolatile FPGA architecture eliminates the need for external configuration memory.
• Speed Grade  Part includes a “-2” speed grade, specified in the SX-A family as approximately 25% faster than the standard speed grade.
• Package & Mounting  100-TQFP surface-mount package (14 × 14 mm) provides compact board integration for space-constrained designs.
• Industrial Temperature Range  Rated for industrial operation from −40 °C to +85 °C.
• System Reliability & Test  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and family features for deterministic, user-controllable timing.
• Security & In-System Diagnostics  SX-A family security features such as Actel Secure Programming Technology (FuseLock™) and in-system diagnostic/verification capability (Silicon Explorer II) for IP protection and debug.
• Regulatory  RoHS compliant.

Typical Applications

• PCI and Bus Interfaces  66 MHz PCI compliance and configurable multi-voltage I/O make this device suitable for PCI-based interface logic and peripheral cards.
• Industrial Control  Industrial temperature rating and mixed-voltage support enable sensor interfacing, motor-control glue logic, and control-plane functions in industrial equipment.
• Embedded System Glue Logic  Nonvolatile single-chip configuration and deterministic timing simplify power-up behavior and reduce external components for embedded control and system integration tasks.
• Signal Conditioning & I/O Bridging  Configurable I/O standards and 5 V tolerance support mixed-voltage signal translation and I/O expansion between legacy and modern subsystem voltages.
