A54SX16P-TQG144M

Overview

The A54SX16P-TQG144M 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 contains 1,452 logic modules (combinatorial cells). The device supports up to 350 MHz internal performance with 250 MHz system performance. It features 113 user-programmable I/O pins and up to 990 dedicated flip-flops within a 144-pin Thin Quad Flat Pack (TQFP) package. The 'M' suffix indicates a military temperature grade operating range of -55°C to +125°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with hot-swap compliant capabilities.
• Features deterministic timing through unique local routing resources such as DirectConnect and FastConnect.
• Includes IEEE 1149.1 (JTAG) boundary-scan testing compliance and FuseLock security technology.

Applications

• High-performance digital signal processing requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Military applications necessitating extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm the exact temperature grade and packaging specifications. Ensure compatibility with existing design tools and verify that the military grade requirements align with project specifications before procurement.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed internal clocking is required. Consider the 144-pin TQFP package constraints and the specific I/O voltage requirements. Verify that the 24,000 gate capacity meets the design complexity needs compared to other SX-A family members.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance designs. The family utilizes antifuse technology, distinguishing it from volatile SRAM-based FPGAs. The SX-A series offers various gate counts and package options to suit different application scales.

FAQ

What is the maximum internal clock frequency supported by the A54SX16P-TQG144M?

The device supports an internal clock frequency of up to 350 MHz.

How does the SX-A architecture ensure secure programming?

It uses Actel Secure Programming Technology with FuseLock, which prevents reverse engineering and unauthorized reading of the antifuse configuration.

Can the I/Os be powered up or down in any order?

Yes, the device is power-up/down friendly, meaning VCCA and VCCI do not have to be stable during power-up/down and can be powered in any order.
