A54SX72A-1FG484M

Overview

The A54SX72A-1FG484M is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 6036 Configurable Logic Blocks (CLBs) and 108,000 system gates. The device operates with a maximum internal clock frequency of 350 MHz and supports up to 360 user-programmable I/O pins. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and is housed in a 484-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. The 'M' suffix indicates a military temperature grade ranging from -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 hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes dedicated quadrant clock networks capable of driving individual chip quadrants or grouped sections.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 via JTAG interface.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Military applications necessitating extended temperature range operation

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture before procurement.

Selection Notes

Select this component when high gate density and fast internal performance are required within a nonvolatile FPGA framework. Consider the 484-pin FBGA package constraints for PCB layout and verify that the military temperature grade meets the environmental specifications of the target application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their sea-of-modules architecture and patented antifuse technology. The family ranges from 12,000 to 108,000 system gates, offering various package options and temperature grades to suit diverse industrial and military design needs.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A series, such as A54SX72A-2FG484M or A54SX72A-FG484M, provided the timing requirements align with the new speed grade specifications.

FAQ

What is the function of the Quadrant Clocks in the A54SX72A?

The A54SX72A provides four quadrant clocks (QCLKA, QCLKB, QCLKC, and QCLKD) that can individually drive an entire quadrant of the chip or be grouped together to drive multiple quadrants.

How does the SX-A architecture handle reverse engineering?

Reverse engineering is difficult because it is hard to distinguish between programmed and unprogrammed antifuses. Additionally, FuseLock technology prevents unauthorized reading of the device contents.

Are the I/Os hot-swappable on all voltage standards?

Most I/Os are hot-swappable, but 3.3 V PCI I/Os are not hot-swappable according to the device specifications.
