Key Features

• Logic Capacity  Provides 2,880 logic elements (cells) and 48,000 system gates for mid-range logic integration.
• I/O Density & Flexibility  203 user-programmable I/Os with configurable support for multiple I/O standards and hot-swap compliant I/Os as described for the SX-A family.
• Performance  SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family specification).
• Nonvolatile Single-Chip Solution  Built as a nonvolatile FPGA for single-chip configuration storage and in-system programmability.
• Voltage Range & Mixed-Voltage Operation  Supports supply voltages from 2.25 V to 5.25 V and family-level configurable I/O support for multiple voltage standards and 5 V tolerance where specified.
• Package & Mounting  256-ball fine-pitch BGA (256-FPBGA, 17×17) in a surface-mount package optimized for PCB integration.
• Power-Up/Down Friendly  Family-level feature: no sequencing required for supply voltages, simplifying multi-rail system bring-up.
• Security & Test  Family features include Actel Secure Programming Technology with FuseLock and IEEE 1149.1 (JTAG) boundary-scan testing support.
• Operating Conditions  Commercial-grade device with an operating temperature range of 0 °C to 70 °C and RoHS-compliant status.
• On-Chip Memory  This device reports 0 total RAM bits (no embedded RAM reported in the product data).

Typical Applications

• PCI and Bus Interfaces  Family-level PCI-compliant I/O support enables implementation of PCI and similar peripheral interfaces where 3.3 V/5 V signaling is required.
• Protocol Bridging and Glue Logic  Mid-range logic capacity and abundant I/Os make the device suitable for protocol bridging, bus translation, and replacing discrete glue logic.
• In-System Programmable Logic  Nonvolatile single-chip architecture and in-system diagnostic capability support field-upgradable logic and verification workflows.
• Boundary-Scan Test Integration  IEEE 1149.1 boundary-scan (JTAG) support facilitates board-level test and manufacturing diagnostics.

Unique Advantages

• Balanced Logic and I/O Count:  2,880 logic elements paired with 203 I/Os provide a balance between compute resources and external connectivity for medium-density designs.
• Nonvolatile Configuration:  Single-chip nonvolatile configuration removes the need for external configuration memory, simplifying system design and reducing components.
• Flexible Voltage Support:  Wide supply range (2.25 V to 5.25 V) and family-level mixed-voltage I/O support reduce the need for level-shifting in multi-voltage systems.
• Production Test and Security:  Boundary-scan testing and secure programming technology support manufacturing testability and intellectual property protection.
• Power-Up/Down Robustness:  No supply sequencing required improves robustness during board power transitions and simplifies power-rail design.
• RoHS Compliance:  RoHS-compliant packaging supports regulatory and environmental requirements for commercial electronic products.
