A54SX32A-BGG329

The A54SX32A-BGG329 is a member of the SX-A family of nonvolatile FPGAs, delivered in a 329-ball BGA package. It provides a programmable logic solution with 48,000 system gates and 2,880 logic elements, supporting up to 249 user I/Os and mixed-voltage operation.

This device targets designs that require on-chip programmability, deterministic timing control, and a high I/O count within a commercial temperature range (0 °C to 70 °C). It supports a wide supply range (2.25 V to 5.25 V) and RoHS-compliant packaging.

Key Features

• Logic Capacity: 48,000 system gates and 2,880 logic elements (cells) to implement complex programmable logic functions.
• User I/O: Up to 249 user-programmable I/O pins, with configurable I/O standards for mixed-voltage operation and 5 V input tolerance.
• Performance: SX-A family performance levels include up to 250 MHz system performance and 350 MHz internal performance as documented for the family.
• Nonvolatile Single-Chip Solution: On-device nonvolatile configuration removes the need for external configuration memory.
• I/O and Bus Support: Hot-swap compliant I/Os and 66 MHz PCI compliance (family-level capability) for peripheral-interface designs.
• Security and Test: Actel Secure Programming Technology with FuseLock for design protection and IEEE 1149.1 (JTAG) boundary-scan testing support.
• Flip-Flops and Registers: Family documentation shows dedicated flip-flop resources; device-level flip-flop capacity supports deterministic, user-controllable timing.
• Package and Mounting: 329-ball plastic BGA (329-PBGA, 31 × 31 mm) surface-mount package suitable for compact board layouts.
• Power and Temperature: Supply range 2.25 V to 5.25 V and commercial operating temperature 0 °C to 70 °C.
• Compliance: RoHS-compliant packaging (G lead-free marking).

Typical Applications

• PCI-compliant peripheral logic: Implement programmable glue logic and interface logic on PCI-based boards using the family’s documented 66 MHz PCI compliance.
• Mixed-voltage system interfaces: Use the device’s configurable I/O and 5 V-tolerant inputs to bridge logic domains and interface legacy TTL/PCI signals.
• In-system diagnostic and verification: Take advantage of the SX-A family in-system diagnostic capabilities and boundary-scan support for board-level testing and verification.

Unique Advantages

• Nonvolatile configuration: Single-chip nonvolatile architecture eliminates external configuration memory and simplifies system power-up behavior.
• High I/O density: 249 user I/Os provide broad connectivity for peripheral interfaces, I/O expansion, and high-pin-count designs.
• Wide supply compatibility: 2.25 V to 5.25 V supply range enables flexible deployment across different logic-voltage domains.
• Security & testability: FuseLock programming technology and IEEE 1149.1 boundary-scan support help protect IP and simplify production test.
• Compact BGA package: 329-ball PBGA (31 × 31 mm) allows a high-pin-count footprint in a compact surface-mount form factor.
• RoHS-compliant: Lead-free packaging supports environmental compliance requirements.
