A54SX08A-2PQG208I

Overview

The A54SX08A-2PQG208I is an antifuse-based FPGA from the Microsemi SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25V to 5.25V and supports up to 130 user I/Os in a 208-pin PQFP package. The device provides 250 MHz system performance with 350 MHz internal clock speeds. It includes three global clocks and complies with IEEE 1149.1 boundary-scan testing standards.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing.
• Utilizes metal-to-metal programmable antifuse technology for nonvolatile, single-chip configuration.

Applications

• High-performance digital logic integration
• PCI-compliant interface designs
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix 'G' indicates RoHS compliant packaging if required by environmental regulations. Confirm the temperature grade 'I' matches industrial specifications (-40°C to +85°C). Ensure the lead-free status aligns with assembly process requirements.

Selection Notes

Select this part for applications requiring deterministic timing and high pin-locking capabilities. The -2 speed grade offers approximately 25% faster performance than standard grades. Consider the 208-pin PQFP package dimensions for PCB layout constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their low-power consumption and high reliability. The SX-A series utilizes a sea-of-modules architecture optimized for register and logic mix flexibility.

Replacement Considerations

Compatible alternatives within the same family include the A54SX08A-1PQG208I (standard speed) or A54SX08A-PQG208I (blank speed). Higher capacity devices like the A54SX16A may be considered if additional logic resources are needed.

FAQ

What is the maximum internal clock frequency supported?

The device supports internal clock frequencies up to 350 MHz.

How does the device handle power-up sequences?

The I/Os are configured to be hot-swappable, meaning VCCA and VCCI do not need to be stable during power-up and can be powered in any order.

Is boundary-scan testing supported?

Yes, all SX-A devices are IEEE 1149.1 compliant and support Boundary-Scan Testing via JTAG pins.
