A54SX08-TQG144

Overview

The A54SX08-TQG144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 12,000 system gates and 768 configurable logic blocks (CLBs). The device provides 113 user-programmable I/O pins and supports up to 2,012 dedicated flip-flops. It operates within a supply voltage range of 2.25 V to 5.25 V and supports mixed-voltage operation with 5 V input tolerance. The maximum operating frequency is 240 MHz, with an internal performance capability of 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and is housed in a TQFP-144 package.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic, user-controllable timing with unique in-system diagnostic capabilities via Silicon Explorer II.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• Integration of 66 MHz PCI compliant designs
• High-performance state machines and fast counters
• Data path logic requiring low propagation delays

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm availability status as distribution channels may list limited stock or obsolete status for older antifuse devices. Ensure the source document matches the exact part number to validate pinout and electrical specifications.

Selection Notes

Select this component when a nonvolatile single-chip FPGA solution with high-speed deterministic timing is required. Consider the 12,000 gate capacity and 113 I/O limit for moderate complexity designs. Verify that the TQFP-144 package fits the PCB footprint constraints and that the commercial temperature range meets the application environment.

Part Context

This device belongs to the Actel SX-A family of FPGAs, which are fabricated using metal-to-metal programmable antifuse technology. The family offers various gate densities ranging from 12,000 to 108,000 system gates. The SX-A architecture is designed for low-power, high-performance applications with support for multiple I/O standards.
