A54SX08A-2TQ100I

The A54SX08A-2TQ100I is an SX-A family field programmable gate array (FPGA) provided in a 100-pin LQFP package and specified for industrial temperature operation. It delivers a nonvolatile, single-chip FPGA solution with 12,000 system gates and 768 logic elements, suitable for designs requiring mixed-voltage I/O, in-system programmability, and deterministic timing control.

Targeted at industrial embedded designs and mixed-voltage interface applications, this device combines configurable I/O flexibility with on-chip logic density and industry-grade temperature support to simplify board-level integration and IP protection.

Key Features

• Core Capacity — 12,000 system gates with 768 logic elements (logical cells) to implement medium-density combinatorial and sequential logic.
• User I/O and Mixed-Voltage Support — 81 user-programmable I/O pins with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 operation; supports mixed 2.5 V, 3.3 V, and 5 V operation with 5 V input tolerance and 5 V drive strength (series-level feature).
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (series-level figures).
• Nonvolatile Single-Chip Solution — integrates configuration storage on-chip to eliminate external configuration memory and simplify power-up behavior.
• Robust I/O Behavior — hot-swap compliant I/Os and power-up/down friendly operation that do not require strict supply sequencing (series-level features).
• Security and Test — supports Actel Secure Programming Technology (FuseLock™) for design protection and boundary-scan testing compliant with IEEE 1149.1 (JTAG) for board-level testability.
• Package and Supply — 100-LQFP package case; voltage supply range 2.25 V to 5.25 V and industrial operating temperature range of −40°C to +85°C.

Typical Applications

• Industrial control and interface logic — 768 logic elements and 81 user I/Os support glue logic, protocol conversion, and control functions in industrial systems operating across mixed-voltage domains.
• PCI and legacy bus interfacing — series-level 66 MHz PCI compliance and configurable I/O voltage support make the device suitable for PCI-compatible interface logic.
• In-system programmable designs — nonvolatile, single-chip configuration and in-system diagnostic capabilities enable field updates and on-board verification without external configuration memory.

Unique Advantages

• Nonvolatile single-chip configuration: Reduces BOM and simplifies board design by removing the need for external configuration memory.
• Mixed-voltage I/O flexibility: Configurable I/Os with 5 V tolerance and selectable standards reduce or eliminate the need for level-shifters between legacy and modern logic domains.
• Industrial temperature rating: Specified operation from −40°C to +85°C supports deployment in industrial environments.
• Secure programmable IP: FuseLock™ secure programming technology protects designs against reverse engineering and unauthorized duplication.
• Test and debug support: Boundary-scan (IEEE 1149.1) and in-system diagnostic capabilities enable streamlined manufacturing test and field diagnostics.
• Deterministic timing control: Series-level deterministic, user-controllable timing enables predictable performance for timing-sensitive logic.

Why Choose A54SX08A-2TQ100I?

The A54SX08A-2TQ100I positions itself as a compact, industrial-grade FPGA option for mid-density logic implementations requiring nonvolatile configuration and flexible, mixed-voltage I/O. With 12,000 system gates, 768 logic elements, and 81 user I/Os in a 100-pin LQFP package, it is well suited to embedded interface logic, PCI-related glue logic, and in-system programmable control functions where board-level simplicity and IP protection matter.

Its industrial temperature rating, broad supply voltage window (2.25 V to 5.25 V), and series-level features—such as hot-swap compliant I/Os, security programming, and boundary-scan—offer a reliable platform for long-term deployed systems that require predictable timing and flexible interfacing.
