A54SX16A-PQG208A

Overview

The A54SX16A-PQG208A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 24,000 system gates and supports up to 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates on a 0.22µ CMOS process with a typical internal performance frequency of 250 MHz. It functions within an extended temperature range of -40°C to +125°C, ensuring reliability for in-cabin telematics and automobile interconnect applications.

Feature Summary

• Features a sea-of-modules architecture with DirectConnect and FastConnect routing for deterministic timing and high-speed signal propagation.
• Includes nonvolatile antifuse technology with FuseLock security to prevent reverse engineering and design theft.
• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Provides boundary scan testing compliance with IEEE Standard 1149.1 and internal probing capabilities via Silicon Explorer II.

Applications

• In-cabin automotive telematics systems
• Automobile interconnect applications
• Performance-intensive logic integration replacing multiple CPLDs

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status and packaging type (G suffix indicates lead-free). Ensure handling procedures account for moisture sensitivity levels specified in the datasheet. Request batch-specific documentation to verify automotive grade qualification and guard-banded testing parameters.

Selection Notes

Select this part when designing for automotive environments requiring operation up to 125°C. The PQFP-208 package offers 175 I/Os suitable for complex interconnect needs. Consider the 250 MHz internal clock speed for high-performance logic. Verify that the 3.3V PCI and LVTTL/LVCMOS2 I/O configurations match system voltage requirements.

Part Context

This component belongs to the Actel SX-A Automotive Family FPGAs, acquired by Microchip Technology. The SX-A series utilizes antifuse technology for permanent configuration. The A54SX16A variant specifically targets mid-range capacity needs within the automotive sector, balancing gate density with power efficiency and robust environmental tolerance.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to specific automotive grading. Evaluate other A54SX16A variants with different packages (e.g., TQFP, FBGA) if form factor changes are acceptable. Cross-reference with standard commercial SX-A devices only if temperature constraints can be relaxed below -40°C.
