A54SX72A-PQG208A

Overview

The A54SX72A-PQG208A 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 6,036 logic array blocks. The device supports up to 360 user-programmable I/Os and includes dedicated flip-flops for sequential logic. It operates within an extended temperature range of -40°C to +125°C and utilizes a 0.22µ CMOS process technology. The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix 'A' confirms the automotive temperature grade (-40°C to 125°C). Confirm the 'G' suffix indicates RoHS-compliant packaging if required. Check current availability status as automotive FPGA lines may undergo discontinuation notices. Ensure the PQFP-208 package matches the target PCB footprint constraints.

Selection Notes

Select this model when high gate density (108,000 system gates) and automotive reliability are required. The PQFP-208 package is suitable for surface-mount assembly where leaded quad flat pack compatibility is needed. Consider the 250 MHz internal performance capability for complex state machines. Verify that the 3.3V PCI and 2.5V LVCMOS2 I/O configurations meet interface requirements.

Part Context

This component belongs to the SX-A Automotive Family FPGAs, which utilize a nonvolatile antifuse architecture. The A54SX72A represents the highest capacity device in this specific series, offering 108,000 system gates. It is designed to replace multiple CPLDs or gate arrays in automotive environments requiring deterministic timing and robust security features.
