A54SX16A-1TQG100

Overview

The A54SX16A-1TQG100 is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 configurable logic blocks. It operates at a maximum frequency of 263 MHz with a supply voltage range of 2.25 V to 2.75 V. The device utilizes a 100-pin Thin Quad Flat Pack (TQFP) package and supports up to 81 user-programmable I/O pins. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Configurable I/O standards supporting mixed-voltage operation including 3.3V, 5V PCI, and TTL levels
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1 for diagnostic verification

Applications

• Industrial control systems requiring deterministic timing and high reliability
• Communication interfaces utilizing 66 MHz PCI compliance
• Embedded logic integration in aerospace or defense environments due to industrial temperature grading
• Prototyping complex digital designs using single-chip nonvolatile FPGA solutions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Ensure compatibility with Actel Designer software versions for programming. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm lead-free packaging availability for modern manufacturing processes.

Selection Notes

Select this model when 24,000 system gates and 100-pin form factor are required. The -1 speed grade offers approximately 15% faster performance than the standard grade. Choose the Industrial temperature grade (-I) for environments ranging from -40°C to +85°C. Consider pin count limitations of 81 I/Os relative to design complexity before committing to the TQFP-100 package.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were later acquired by Microchip Technology. The SX-A series is characterized by its metal-to-metal antifuse technology, offering instant-on capabilities and high security against reverse engineering. It serves as a bridge between CPLDs and larger SRAM-based FPGAs in terms of capacity and performance.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other devices from the A54SX16A series with different speed grades or temperature ratings, such as A54SX16A-2TQG100I. Verify logical resource equivalence and timing requirements when substituting speed grades.
