A54SX08-PLG84

Overview

The Microsemi A54SX08-PLG84 is an SX-A series Field Programmable Gate Array (FPGA) utilizing antifuse technology. It provides 12,000 system gates and 768 logic modules, comprising 512 combinatorial cells and 256 dedicated flip-flops. The device supports up to 69 user-programmable I/O pins within a 84-pin PLCC package. It operates with mixed-voltage support for 2.5 V, 3.3 V, and 5 V I/Os, featuring 5 V input tolerance. Internal performance reaches 350 MHz, while system performance is rated at 250 MHz.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without supply voltage sequencing requirements.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Includes Boundary-Scan Testing compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• Low-power, high-performance designs requiring single-chip integration
• Systems requiring deterministic timing and user-controllable delays
• Applications needing mixed-voltage I/O interfacing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm current availability status as legacy components may have limited production runs or discontinuation notices. Ensure the selected variant matches the required environmental operating range for the target application.

Selection Notes

Select this component when antifuse nonvolatility and security are prioritized over reprogrammability. Evaluate the 768 CLB capacity against design complexity requirements. Consider the 84-pin PLCC package constraints for PCB layout and thermal management during the initial design phase.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers various gate counts and package options, positioning the A54SX08A as a mid-range solution for cost-effective, secure logic integration compared to larger devices like the A54SX32A.

Replacement Considerations

Direct pin-compatible replacements within the same package type are not explicitly documented in the provided datasheet. Verify if other speed grades or temperature variants of the A54SX08A series meet functional requirements before considering alternative manufacturers.
