A54SX16A-1FG144I

Overview

The A54SX16A-1FG144I is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules (CLBs). The device supports up to 111 user-programmable I/Os and features 3 global clocks. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes configurable weak-resistor pull-up or pull-down capabilities for I/O pins at power-up.
• Features deterministic, user-controllable timing with individual output slew rate control.

Applications

• High-performance designs requiring low power consumption
• Systems needing 66 MHz PCI compliance
• Applications requiring mixed-voltage operation with 5 V input tolerance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the FBGA-144 configuration. Confirm that the antifuse technology aligns with long-term availability requirements, as these devices are non-reprogrammable once configured.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate external configuration memory. The SX-A family offers high-speed internal performance suitable for complex logic integration. Consider the available I/O standards, including support for 3.3 V, 5 V PCI, and TTL levels, to ensure interface compatibility with system components.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, high-performance applications. The family includes devices ranging from 8,000 to 108,000 system gates. The A54SX16A variant specifically targets designs needing moderate logic density with robust I/O flexibility and security features like FuseLock™.
