A54SX32A-1BG329I

The A54SX32A-1BG329I is a member of the SX-A family of nonvolatile FPGAs, offering 48,000 system gates and 2,880 logic elements in a 329-ball BGA package. It supports up to 249 user I/Os and is supplied in an industrial temperature grade (–40 °C to 85 °C).

Designed for applications that require dense I/O, mixed‑voltage interfacing and nonvolatile single‑chip operation, this device combines configurable I/O flexibility, secure on-chip programming and a wide supply range (2.25 V to 5.25 V) to simplify system integration.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements provide high-density programmable logic for glue logic, protocol handling and control functions.
• I/O Density & Configurability — 249 user I/Os with configurable 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 selectable drive strength.
• Nonvolatile Single‑Chip Architecture — SX-A family nonvolatile configuration eliminates the need for external configuration memory and provides power‑up/down friendly behavior.
• Performance Options — Part is a “–1” speed grade (approximately 15% faster than standard) as defined for the SX-A family; the family supports system performance listings up to 250 MHz and internal performance up to 350 MHz.
• Power & Voltage — Operates across a wide supply range from 2.25 V to 5.25 V, enabling integration into mixed‑voltage systems without complex supply sequencing.
• Security & In‑System Diagnostics — Actel Secure Programming Technology (FuseLock™) protects design IP; SX-A family includes in‑system diagnostic and verification capabilities.
• Standards & Testability — Hot‑swap compliant I/Os, power‑up/down friendly operation and IEEE‑1149.1 boundary‑scan (JTAG) support for board‑level test and debug.
• Package & Mounting — Surface-mount 329‑ball BGA (supplier package: 329‑PBGA, 31×31) suitable for high‑density PCBs; RoHS compliant.
• Embedded Memory — No embedded RAM (Total RAM Bits: 0), enabling deterministic logic resource allocation when on‑chip RAM is not required.

Typical Applications

• Interface and Glue Logic — Use the high I/O count and configurable voltage support to implement board-level protocol bridging, bus interfacing and signal adaptation.
• PCI and Legacy Bus Integration — SX-A family PCI‑compliant features make the device suitable for 66 MHz PCI interface functions and associated glue logic.
• Industrial Control and I/O Handling — Industrial temperature rating (–40 °C to 85 °C) and wide supply range support robust I/O aggregation and control functions in industrial equipment.
• Secure, Nonvolatile Logic — FuseLock programming and nonvolatile single‑chip configuration are useful where on‑board configuration security and simplified power sequencing are required.

Unique Advantages

• High I/O Count: 249 programmable I/Os enable complex signal routing and multiple peripheral interfaces without external multiplexers.
• Nonvolatile Single‑Chip Solution: Eliminates external configuration memory and simplifies system power sequencing and board design.
• Wide Voltage Flexibility: 2.25 V–5.25 V supply range and mixed‑voltage I/O support reduce the need for level‑shifters and additional power rails.
• Security Built In: FuseLock programming technology protects intellectual property with on‑chip secure programming.
• Industrial Temperature Grade: –40 °C to 85 °C rating supports deployment in temperature‑challenging environments common to industrial applications.
• Test and Debug Support: Boundary‑scan (IEEE‑1149.1) and in‑system diagnostic capability aid production test and field diagnostics.
