A54SX08A-2TQ100

Overview

The A54SX08A-2TQ100 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 12,000 system gates and 81 user I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide a nonvolatile, single-chip solution. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance logic integration requiring low-power consumption
• Systems demanding hot-swappable interface capabilities
• Applications requiring secure, nonvolatile programmable logic solutions

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 board layouts regarding the TQFP-100 footprint and pin assignments. Confirm that the selected speed grade meets the required system clock frequencies for the intended application.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices. Consider the SX-A family for designs requiring mixed-voltage I/O standards including 5V TTL and PCI compliance. Evaluate the available global and quadrant clock resources if complex timing synchronization is necessary for the design.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal antifuse interconnect technology. The family offers various gate counts and package options, ranging from small-scale logic modules to high-density arrays. The SX-A series is designed for applications needing robust security features and deterministic performance characteristics.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX08A series, such as the standard or faster variants. Cross-family migration may require significant schematic and layout changes due to architectural differences between antifuse and SRAM-based FPGAs.

FAQ

What is the maximum internal clock frequency supported by the SX-A family?

The SX-A family devices support internal clock frequencies up to 350 MHz.

How does the SX-A family handle power-up and down sequences?

The I/Os are configured to be hot-swappable, allowing VCCA and VCCI to be powered up or down in any order without causing damage to the host system.

Is Boundary Scan Testing supported on this device?

Yes, all SX-A devices are IEEE 1149.1 compliant and offer Boundary Scan Testing (BST) capabilities via JTAG pins.
