A54SX08-1TQ144I

Overview

The A54SX08-1TQ144I is an industrial-grade Field Programmable Gate Array from the SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25V to 5.25V and supports up to 113 user-programmable I/O pins in a 144-pin Thin Quad Flat Pack (TQFP) package. The device achieves a maximum system performance of 250 MHz with internal clock frequencies reaching 350 MHz. Designed for robust applications, it functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Includes nonvolatile antifuse technology that prevents reverse engineering and design theft
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect

Applications

• Industrial control systems requiring deterministic timing and high reliability
• Hot-swappable hardware configurations where system uptime is critical
• Secure embedded designs needing protection against intellectual property extraction

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the package type matches the 144-pin TQFP specification. Ensure the speed grade '1' aligns with the required system performance targets. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a balance of moderate logic density and high-speed performance is required. The SX-A architecture offers full pin-locking capabilities, which simplifies PCB layout by ensuring fixed signal paths. Consider the nonvolatile nature of the device to eliminate external configuration memory requirements in the system design.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse technology. The family provides a single-chip solution integrating logic, interconnect, and I/Os. The A54SX08 variant represents the entry-level capacity within the series, offering 12,000 typical system gates suitable for complex CPLD replacements or small-scale integration tasks.

Replacement Considerations

Direct functional equivalents are limited due to the proprietary antifuse architecture. Review the A54SX08A datasheet for alternative packages such as PQFP or PBGA if pin counts differ. Verify compatibility with existing programming tools, as newer Microchip devices may require updated Libero SoC software versions.
