A54SX72A-2FGG256I

The A54SX72A-2FGG256I is an SX-A family FPGA from Microchip Technology delivered in a 256-pin fine-pitch BGA package. This industrial-grade, surface-mount device provides 108,000 system gates and 6,036 logic elements with up to 203 user-programmable I/Os for mid-to-high density programmable logic implementations.

Designed for mixed-voltage embedded designs, the device supports a 2.25 V to 5.25 V supply range and operates across an industrial temperature window of −40°C to 85°C. As a member of the SX-A family, it offers nonvolatile single-chip operation and a suite of series-level features aimed at reliable in-system deployment.

Key Features

• Logic Capacity — 108,000 system gates and 6,036 logic elements provide substantial programmable logic resources for complex glue logic, protocol handling, and control tasks.
• User I/O — 203 user-programmable 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 mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance — SX-A family specifications include up to 250 MHz system performance and up to 350 MHz internal performance; the –2 speed grade denotes approximately 25% faster performance than the standard grade per the family speed-grade definitions.
• Package — 256-pin fine-pitch BGA (256-FPBGA, 17×17) in a surface-mount form factor for compact board integration.
• Voltage and Temperature — Wide supply range of 2.25 V to 5.25 V and industrial operating temperature rating from −40°C to 85°C.
• Nonvolatile, Single-Chip Solution — Series-level nonvolatile architecture removes the need for external configuration memory for field-upgradable systems.
• Design and Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic capability with Silicon Explorer II as described for the SX-A family.
• Security — Includes Actel Secure Programming Technology (FuseLock™) as documented for the SX-A family to help protect bitstream confidentiality.
• I/O Robustness — Hot-swap compliant I/Os and configurable weak pull-up/pull-down on power-up for board-level reliability in complex power environments.
• Mounting Type — Surface mount design suitable for automated PCB assembly processes.

Typical Applications

• Industrial Control — Implement control logic, protocol translation, and I/O aggregation in factory automation and industrial instrumentation using industrial temperature-rated operation.
• PCI-Based Add-on Cards — 66 MHz PCI compliance and multi-voltage I/O support enable use on PCI or mixed-voltage expansion cards and interface bridges.
• Communications and Networking — Use the device for mid-density packet handling, timing-critical logic, and in-system diagnostics in communication equipment.
• Embedded Systems — Deploy as the programmable logic element for embedded controllers, protocol adaptors, and feature-rich peripherals where nonvolatile configuration is required.

Unique Advantages

• High Logic Density: 108,000 system gates and 6,036 logic elements reduce the need for multiple discrete devices in mid-density designs.
• Mixed-Voltage Flexibility: On-package support for 2.5 V, 3.3 V and 5 V operation with 5 V tolerance simplifies level-shifting and mixed-supply board design.
• Industrial Qualification: Specified for −40°C to 85°C operation, making it suitable for temperature-challenging environments.
• Nonvolatile Operation: Single-chip nonvolatile architecture eliminates external configuration memory and streamlines system power-up behavior.
• Built-in Security and Test: FuseLock™ programming technology and IEEE 1149.1 boundary-scan support protect IP and ease manufacturing test.
• In-System Diagnostics: Family-level support for Silicon Explorer II offers diagnostic and verification capabilities for in-field troubleshooting and validation.
