• User I/O  Up to 203 user I/O pins in the 256-FPBGA package, with configurable I/O standards and individual output slew-rate control.
• Package and Mounting  256-pin fine-pitch BGA (256-FPBGA, 17×17) optimized for surface-mount assembly in space-constrained boards.
• Voltage Supply  Supports a device supply range from 2.25 V to 5.25 V, enabling 2.5 V, 3.3 V and 5 V mixed-voltage operation where supported by the family.
• Performance  Family-level performance includes up to 250 MHz system performance and 350 MHz internal performance for timing-critical designs.
• Nonvolatile Single-Chip Configuration  Single-chip, nonvolatile configuration eliminates the need for external configuration memory and simplifies board-level design.
• Security and Test  Family features include Actel Secure Programming Technology with FuseLock™ to protect design IP and IEEE 1149.1 (JTAG) boundary-scan testing support.
• Diagnostics  In-system diagnostic and verification capability is supported through Silicon Explorer II for design validation and field diagnostics.
• Operating Range & Compliance  Commercial-grade device with an operating temperature range of 0 °C to 70 °C and RoHS-compliant packaging.

Typical Applications

• PCI and Bus Interface Designs  Family support for 3.3 V / 5 V PCI and mixed-voltage I/O makes the device suitable for implementing PCI-compliant interfaces and other bus bridging functions.
• Secure Embedded Systems  Nonvolatile configuration and FuseLock™ programming support designs that require on-chip IP protection and secure boot capability.
• Compact, High-Density Products  The 256-FPBGA package and high logic density enable compact board layouts for commercial electronics and compact system designs.
• In-System Verification and Diagnostics  Use the device’s in-system diagnostic features for field verification and debugging during development and maintenance.

Unique Advantages
