A54SX16A-1TQG100M

The A54SX16A-1TQG100M is a military-grade SX-A family FPGA offering 24,000 system gates and 1,452 logic elements in a 100-pin LQFP package. It delivers a nonvolatile, single-chip FPGA architecture with configurable I/O and a broad supply range, designed for embedded systems requiring deterministic timing and rugged operating conditions.

Typical uses include embedded control and interface functions where secure in-system programmability, mixed-voltage I/O support, and extended temperature operation are required. The device combines mid-range logic capacity with series-level capabilities such as hot-swap compliant I/Os, JTAG boundary-scan, and secure programming features.

Key Features

• Logic Capacity — 24,000 system gates and 1,452 logic elements provide mid-range programmable logic resources for control, glue-logic and interface designs.
• I/O Density & Flexibility — 81 user I/Os with configurable I/O supporting 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling and individual output slew-rate control.
• Performance — Series-level performance indicators list up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• Power & Supply — Wide supply tolerance from 2.25 V to 5.25 V and power-up/down friendly behavior that does not require sequencing of supply rails.
• Robust Packaging & Temperature — 100-LQFP package (supplier notes 100-TQFP, 14×14) and military-grade temperature rating from −55 °C to +125 °C.
• System Reliability & Testability — IEEE 1149.1 boundary-scan (JTAG) support and in-system diagnostic and verification capability with Silicon Explorer II.
• Security — Actel Secure Programming Technology with FuseLock™ to protect designs against reverse engineering.
• Hot-Swap & PCI Support — Hot-swap compliant I/Os and 66 MHz PCI compliance for board-level hot-insert and legacy interface applications.

Typical Applications

• Military and Rugged Embedded Systems — Military-grade temperature range and durable packaging make this FPGA suitable for mission-critical control and signal-processing tasks in harsh environments.
• Interface and Glue Logic — Configurable I/O standards and 81 user I/Os support bridging and protocol adaptation between mixed-voltage domains.
• Secure Systems and IP Protection — FuseLock secure programming and in-system diagnostic features support designs that require anti-tamper and verification capabilities.
• PCI-Capable Boards — 66 MHz PCI compliance and hot-swap I/O suitability make the device useful for PCI interface logic and hot-pluggable board subsystems.

Unique Advantages

• Nonvolatile, Single-Chip Solution: Eliminates the need for external configuration memory, simplifying BOM and system integration.
• Wide Voltage and I/O Compatibility: Supports multiple I/O standards and a broad supply range (2.25 V–5.25 V) for flexible interfacing across legacy and modern domains.
• Rugged Temperature Rating: Military-grade operation from −55 °C to +125 °C supports deployment in extreme environments.
• Deterministic Timing and Diagnostics: Series features include deterministic, user-controllable timing and in-system diagnostic support for predictable system behavior and testability.
• Security-Oriented Programming: FuseLock programming technology reduces risk of IP theft and reverse engineering.
