A54SX32A-2TQG100I

The A54SX32A-2TQG100I is a member of the SX-A family of nonvolatile, single-chip FPGAs. It delivers 48,000 system gates and 2,880 logic elements in a 100-pin thin quad flat pack (TQFP) package optimized for surface-mount assembly.

Designed for industrial applications, this device supports 81 user I/Os, a wide supply-voltage operating range from 2.25 V to 5.25 V, and an operating temperature range of −40 °C to 85 °C. The SX-A architecture provides features useful for system integration, in-system diagnostics and secure programming.

Key Features

• Core & Capacity — 48,000 system gates and 2,880 logic elements provide programmable logic density for medium-complexity designs.
• Performance — SX-A family performance targets are specified in the series datasheet as 250 MHz system performance and up to 350 MHz internal performance.
• I/O — 81 user-programmable I/Os in the 100-pin TQFP; I/O architecture in the SX-A family supports configurable voltage domains and hot-swap–friendly behavior.
• Voltage & Power — Operates across a 2.25 V to 5.25 V supply range, enabling mixed-voltage system integration and flexibility at the board level.
• Memory — No on-chip RAM (Total RAM Bits: 0); suitable for designs that use external memory or rely on flip-flop resources.
• Package & Mounting — 100-LQFP (TQFP 14×14) surface-mount package for standard SMT assembly processes and compact board footprints.
• Temperature Grade — Industrial-grade operation from −40 °C to 85 °C for deployment in industrial environments.
• System & Reliability Features — Nonvolatile single-chip configuration, boundary-scan (IEEE 1149.1) support, and in-system diagnostic/verification with Silicon Explorer II as described in the SX-A documentation.
• Security — Includes Actel Secure Programming Technology with FuseLock™ to protect bitstream and prevent reverse engineering, as documented for the SX-A family.

Typical Applications

• Industrial Control — Implement control logic, glue logic, or protocol bridging in industrial automation systems where industrial-temperature components and reliable nonvolatile configuration are required.
• PCI and Bus Interfaces — SX-A family devices document 66 MHz PCI compliance and configurable I/O levels, making this device suitable for bus interface, logic adaptation, and PCI-related glue logic.
• Field-Upgradeable Logic — Nonvolatile, single-chip configuration with in-system diagnostics enables field updates and verification without external configuration memory.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates the need for external configuration memory, simplifying board design and BOO/T sequences.
• Wide Supply Range: 2.25 V to 5.25 V operation supports mixed-voltage systems and 5 V tolerance where required by system I/O standards.
• Industrial Temperature Rating: Specified operation from −40 °C to 85 °C for deployment in industrial environments.
• Configurable, Hot-Swap Friendly I/Os: I/O features in the SX-A family allow configurable pull-ups/pull-downs and hot-swap–compliant behavior to ease board-level integration.
• Diagnostics and Security: In-system diagnostic capability with Silicon Explorer II and FuseLock secure programming provide verification and design protection options.
• Compact SMT Package: 100-pin TQFP (14×14) delivers a compact footprint for space-constrained designs while maintaining ample I/O count.
