A54SX16A-2FGG144I

Overview

The A54SX16A-2FGG144I is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates at a maximum clock frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package and is rated for industrial temperature grades ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through user-controllable output slew rates and configurable weak-resistor pull-ups or pull-downs during power-up.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions.
• Systems requiring 66 MHz PCI compliance and mixed-voltage interface support.
• Applications necessitating secure programming with protection against reverse engineering.

Procurement Notes

Verify the specific ordering suffixes to confirm the package type, speed grade, and temperature range match the design requirements. Ensure that the FBGA144 footprint corresponds to the 1.0 mm pitch specification defined in the datasheet. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when 24,000 system gates and 1,452 logic modules are sufficient for the design complexity. The -2 speed grade offers approximately 25% faster performance than the standard grade. Consider the FBGA144 package if high pin density and compact board space are critical constraints for the application.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The SX-A series provides a cost-effective platform for low-power, high-performance designs. The A54SX16A variant specifically targets applications needing moderate logic capacity with robust I/O flexibility and security features inherent to the antifuse architecture.

Replacement Considerations

Direct replacements within the same family include other A54SX16A variants with different speed grades or packages, such as A54SX16A-1FGG144I or A54SX16A-TQG144I. Verify compatibility regarding pinout and electrical characteristics before substitution.
