A54SX72A-PQ208A

Overview

The A54SX72A-PQ208A is an automotive-grade Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 108,000 system gates and supports up to 360 user-programmable I/O pins. The device operates within a temperature range of -40°C to 125°C and utilizes a 0.22µ CMOS process technology. It includes dedicated flip-flops for sequential logic and offers internal performance capabilities up to 250 MHz. The PQFP-208 package provides surface-mount installation.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes boundary scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic and verification purposes.
• Features Actel’s FuseLock security technology to prevent reverse engineering and design theft.
• Provides individual output slew rate control and configurable weak-resistor pull-up or pull-down options at power-up.

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive embedded logic designs

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status as packaging suffixes may vary. Check for end-of-life notifications or discontinuance updates prior to finalizing procurement plans. Ensure storage conditions meet humidity sensitivity level requirements to prevent moisture damage during assembly.

Selection Notes

Select this model when high gate density and automotive temperature ratings are required. Consider the PQFP-208 package constraints regarding pin count and board space. Evaluate the need for quadrant clocks available only in the A54SX72A variant compared to smaller devices in the family. Verify I/O voltage compatibility with 3.3V PCI or LVTTL standards.

Part Context

This part belongs to the SX-A Automotive Family FPGAs, which are designed for harsh environments. The SX-A series uses antifuse technology for nonvolatile configuration. The A54SX72A represents the highest capacity device in this specific automotive grade lineup, offering superior routing resources and clock networks compared to lower-density counterparts like the A54SX08A or A54SX16A.

Replacement Considerations

Direct replacements within the same package and functionality include other A54SX72A variants with different speed grades or packages, such as A54SX72A-FGG256I. Cross-family migration to RT54SX72S requires architectural adaptation due to differences in clocking and I/O structures.
