A54SX16A-TQG100M

Overview

The A54SX16A-TQG100M is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 81 user-programmable I/O pins. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to deliver up to 250 MHz system performance and 350 MHz internal clock speeds. The device operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V supply. It is housed in a 100-pin Thin Quad Flat Pack (TQFP) package with a height of 1.40 mm. The component supports mixed-voltage operation including 3.3 V and 5 V standards.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Features power-up/down friendly design requiring no sequencing for supply voltages
• Includes individual output slew rate control and configurable weak-resistor pull-ups or pull-downs
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• PCI-compliant designs operating at 66 MHz
• Mixed-voltage interface applications supporting 3.3 V, 5 V, and 2.5 V standards
• High-performance logic integration requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging details. Confirm current production status as speed grades may be discontinued. Ensure compatibility with Actel Designer software versions for programming and verification.

Selection Notes

Select this model for designs requiring approximately 24,000 system gates with an 81-pin I/O count in a TQFP-100 package. Verify that the standard speed grade meets the 250 MHz system performance requirement. Check if the commercial temperature range is sufficient for the intended application environment.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are now manufactured by Microchip Technology. The SX-A series is characterized by its nonvolatile antifuse architecture, offering high performance and security through FuseLock technology. It serves as a single-chip solution for low-power, high-speed digital logic applications.

Replacement Considerations

Check for updated speed grades or packages within the A54SX16A series. Verify availability of industrial or automotive temperature variants if environmental conditions require them. Consult Microchip for any discontinued package options.
