A54SX16A-1TQ100

The A54SX16A-1TQ100 is a commercial-grade, nonvolatile FPGA from the SX-A family designed for embedded logic implementations requiring up to 24,000 system gates. The device integrates approximately 1,452 logic elements and 81 user-programmable I/O pins in a 100-pin surface-mount package, making it suitable for compact, single-chip programmable designs.

Built on the SX-A family architecture, the part delivers family-level performance characteristics and I/O flexibility that target control, interface and system-logic applications where nonvolatile configuration, mixed-voltage I/O and deterministic timing are important.

Key Features

• Core Capacity — Approximately 24,000 system gates and 1,452 logic elements provide the programmable resources for medium-complexity logic functions.
• Performance (SX-A family) — Family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance as published for the SX-A family.
• I/O Flexibility — 81 user I/Os with configurable support for multiple signaling standards on the SX-A family, including 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2.
• Voltage and Mixed-Voltage Operation — Device supply range 2.25 V to 5.25 V and documented family support for 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V input tolerance.
• Nonvolatile Single-Chip Configuration — SX-A family nonvolatile architecture eliminates the need for an external configuration memory device for single-chip deployment.
• System Reliability Features — Hot-swap compliant I/Os, power-up/power-down friendly operation (no sequencing required for supply voltages), and IEEE 1149.1 boundary-scan (JTAG) support from the SX-A family.
• Configurable I/O Options — Configurable weak-resistor pull-up or pull-down at power-up and individual output slew-rate control are supported at the family level.
• Diagnostics and Security — In-system diagnostic and verification capability with Silicon Explorer II and Actel Secure Programming Technology with FuseLock™ to protect designs (SX-A family features).
• Package and Mounting — 100-pin LQFP surface-mount package; supplier device package noted as 100-TQFP (14 × 14 mm).
• Environmental and Grade — Commercial temperature grade (0 °C to 70 °C) and RoHS compliant.

Typical Applications

• Embedded Control — Implement medium-complexity control logic and state machines with on-chip, nonvolatile configuration and deterministic timing.
• Interface Bridging — Create mixed-voltage interface logic and protocol glue between 2.5 V, 3.3 V and 5 V domains using the device’s configurable I/O support.
• PCI and Legacy Bus Support — Leverage the SX-A family’s documented 66 MHz PCI compliance for interfacing legacy bus systems where required.
• In-System Diagnostics — Use in-system verification and diagnostic features (Silicon Explorer II support) to validate logic and aid debugging during development.

Unique Advantages

• Single-Chip Nonvolatile Solution: Integrated nonvolatile configuration removes the need for external configuration memory in single-chip designs.
• Mixed-Voltage I/O Compatibility: Broad I/O signaling support and 5 V input tolerance allow flexible interfacing to legacy and modern logic families.
• Compact Surface-Mount Package: 100-pin LQFP/TQFP packaging provides a small footprint for space-constrained boards while keeping ample I/O available.
• Commercial Temperature Suitability: Rated for 0 °C to 70 °C operation to match commercial product requirements.
• Design Protection and Diagnostics: FuseLock secure programming and in-system diagnostic capability support IP protection and field verification.
• RoHS Compliant: Meets RoHS requirements for environmental compliance.
