A54SX32-2BGG329I

The A54SX32-2BGG329I is a nonvolatile SX-A family FPGA from Microchip Technology, delivered in a 329-ball BGA package with surface-mount construction and industrial temperature rating (‑40 °C to 85 °C). It provides a mid-range logic capacity and high I/O density for system designs that require configurable logic, deterministic timing and mixed-voltage I/O support.

Built for applications that demand a combination of integration and reliable operation, this device combines approximately 48,000 system gates with 2,880 logic elements and 249 user-programmable I/O pins in a RoHS-compliant package.

Key Features

• Core performance: System performance up to 250 MHz and internal performance up to 350 MHz as specified for the SX-A family, supporting responsive logic operation.
• Logic capacity: Approximately 48,000 system gates and 2,880 logic elements, providing mid-range programmable logic density for control, glue-logic and interface functions.
• I/O density and flexibility: 249 user I/O pins with configurable I/O support for multiple voltage standards and mixed-voltage operation (2.5 V, 3.3 V, 5 V); device-level supply support from 3 V to 5.5 V.
• Nonvolatile single-chip configuration: Single-chip, nonvolatile architecture eliminates the need for external configuration memory and enables immediate functional availability after power-up.
• Power and system friendliness: Hot-swap compliant I/Os and power-up/power-down friendly operation with no sequencing required for supply voltages, simplifying system power management.
• System interfaces and standards: SX-A family support for 66 MHz PCI and IEEE 1149.1 boundary-scan (JTAG) testing provides protocol and testability options for system integration.
• Security and diagnostics: Secure programming technology with FuseLock™ protection and in-system diagnostic/verification capability (Silicon Explorer II) as provided in SX-A family documentation.
• Package and environmental: 329-ball BBGA package (supplier package: 329-PBGA, 31×31), surface mount, RoHS compliant, and industrial temperature grade (‑40 °C to 85 °C).

Typical Applications

• Industrial control and automation: High I/O count and industrial temperature rating support sensor interfacing, I/O aggregation and real-time control logic in factory and process equipment.
• Mixed-voltage interface bridging: Configurable I/O with 2.5 V/3.3 V/5 V support enables board-level protocol conversion and signal translation without extensive level-shifter circuitry.
• PCI-based systems and legacy interfaces: Family-level support for 66 MHz PCI makes the device suitable for designs that require legacy PCI connectivity and related glue logic.
• Embedded systems with immediate availability: Nonvolatile single-chip configuration eliminates external configuration storage, simplifying boot behavior in embedded products.

Unique Advantages

• Nonvolatile integration: On-chip nonvolatile configuration removes the need for external configuration PROMs, reducing BOM and board complexity.
• High I/O per package: 249 user I/Os in a 329-ball BGA provides dense I/O routing capability for complex interfacing without increasing package count.
• Mixed-voltage I/O support: Native support for 2.5 V, 3.3 V and 5 V interfaces reduces the need for external level-shifting and simplifies multi-voltage board designs.
• Industrial temperature grade: Qualified for operation from ‑40 °C to 85 °C, enabling deployment in industrial environments and equipment.
• Built-in test and security: JTAG boundary-scan and FuseLock secure programming provide testability and design protection options for production and field service.
• Power-up friendly I/Os: Hot-swap compliance and no required supply sequencing reduce power-management constraints during system integration.
