Key Features

• Core Performance  250 MHz system performance and 350 MHz internal performance as defined by the SX-A family architecture for responsive logic and control paths.
• Logic Capacity  Approximately 48,000 system gates and 2,880 logic elements to implement mid-range programmable logic functions.
• I/O Density  249 user-programmable I/Os to support complex interface requirements and multiple peripheral connections.
• Mixed-Voltage Support  Configurable I/O support for 5 V TTL, 3.3 V LVTTL, 2.5 V LVCMOS2 and mixed 2.5 V/3.3 V/5 V operation with 5 V input tolerance and 5 V drive strength.
• PCI Compatibility  66 MHz PCI-compliant I/O options and configurable I/O settings suitable for PCI-based designs.
• Power and Reliability  Power-up/power-down friendly design requiring no sequencing of supply voltages and hot-swap compliant I/Os to ease system integration.
• Security and Testability  Actel Secure Programming Technology with FuseLock™ prevents reverse engineering; IEEE 1149.1 boundary-scan (JTAG) is supported for board-level testing.
• Package and Mounting  329-ball PBGA (31 × 31) package, surface-mount mounting type—RoHS-compliant.
• Supply and Temperature  Operates from 3 V to 5.25 V with a commercial operating temperature range of 0 °C to 70 °C.

Typical Applications

• PCI and expansion interfaces  Implement PCI-compliant logic and bridging functions using the device’s 66 MHz PCI support and configurable 3.3 V/5 V I/O.
• Mixed-voltage system I/O  Bridge and interface subsystems that require 2.5 V, 3.3 V, and 5 V signaling with 5 V input tolerance and drive capability.
• In-system configurable control  Use the nonvolatile single-chip FPGA for field-configurable control logic, leveraging 249 user I/Os and on-chip diagnostic capability.
• Secure IP protection  Deploy designs requiring anti-reverse-engineering protection using the built-in FuseLock secure programming technology.

Unique Advantages

• Nonvolatile single-chip solution: Eliminates external configuration memory, simplifying board design and boot-up behavior.
