A54SX16A-TQ100

The A54SX16A-TQ100 is a member of the SX-A family of nonvolatile, single-chip FPGAs. It provides 1,452 logic elements (LEs) and 24,000 system gates in a 100-pin thin quad flat pack (TQFP) surface-mount package with 81 user I/Os, targeting commercial embedded designs that require configurable, mixed-voltage I/O and deterministic timing.

Family-level performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance. The device’s mix of configurable I/O, single-chip nonvolatile configuration and in-system diagnostic features make it suitable for designs that need flexible interfacing, secure programming and board-level testability.

Key Features

• Logic Capacity — 1,452 logic elements and approximately 24,000 system gates provide a compact programmable fabric for mid-range logic integration.
• User I/O — 81 user-programmable I/O pins with configurable I/O standards enabling mixed-voltage operation (2.5 V, 3.3 V, 5 V) and 5 V input tolerance.
• Nonvolatile Single-Chip Configuration — Single-chip, nonvolatile architecture simplifies system design by eliminating the need for external configuration memory.
• Voltage and Power — Wide supply range from 2.25 V to 5.25 V supports mixed-voltage systems and flexible board-level power architectures.
• No On-Chip RAM — Total on-chip RAM bits: 0, for designs that rely on flip-flops and external memory for state storage.
• Performance (Family) — SX-A family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance.
• I/O and System Control — Hot-swap compliant I/Os, configurable weak pull-up/pull-down on power-up, individual output slew rate control and support for PCI signaling options (3.3 V / 5 V PCI).
• Security and Test — Actel Secure Programming Technology with FuseLock™ for protection against reverse engineering and IEEE 1149.1 (JTAG) boundary-scan for board-level test and debug.
• Package and Mounting — 100-pin TQFP (14 × 14 mm) package, surface-mount mounting type, commercial temperature grade (0 °C to +70 °C).
• RoHS Compliance — Device is RoHS compliant for lead-free manufacturing processes.

Typical Applications

• Commercial Embedded Systems — Implement glue logic, custom peripherals and control functions where a compact, nonvolatile FPGA fabric and mixed-voltage I/O are required.
• Board-Level Interface and PCI Peripherals — Support for 3.3 V / 5 V PCI and configurable I/O makes the device suitable for implementing PCI-compliant interfaces and peripheral controllers.
• In-System Test and Diagnostics — JTAG boundary-scan and in-system diagnostic capabilities assist manufacturing test and field verification of board-level interconnects.
• Secure Logic Implementation — FuseLock secure programming technology is useful for designs requiring protection against IP extraction and reverse engineering.

Unique Advantages

• Compact, Mid-Range Integration: 1,452 logic elements and 24,000 system gates provide room for substantial logic consolidation while keeping board space and BOM complexity down.
• Single-Chip Nonvolatile Configuration: Eliminates the need for external configuration memories and simplifies power-up behavior and supply sequencing.
• Flexible Mixed-Voltage I/O: 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V tolerance enables direct interfacing to a wide range of legacy and modern peripherals.
• Design Security: FuseLock programming technology provides a hardware-level measure to help prevent reverse engineering of the programmed design.
• Manufacturing and Field Testability: IEEE 1149.1 boundary-scan and in-system diagnostic features support efficient board bring-up and fault isolation.
• Commercial Temperature and RoHS Compliance: Commercial temperature rating (0 °C to +70 °C) and RoHS compliance align the device with standard commercial production environments and regulations.
