A54SX08A-TQ100I

Overview

The A54SX08A-TQ100I is an industrial-grade FPGA from the SX-A family, featuring 12,000 system gates and a 100-pin Thin Quad Flat Pack (TQFP) package. It operates within a voltage range of 2.25V to 5.25V and supports up to 81 user I/Os. The device provides 768 logic modules, including 512 dedicated flip-flops, and includes three global clock networks. It utilizes 0.22μm/0.25μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements
• Configurable I/O support for mixed-voltage operation including 3.3V/5V PCI, 5V TTL, and 2.5V LVCMOS2
• Deterministic timing with unique local routing resources DirectConnect and FastConnect

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Industrial applications necessitating -40°C to +85°C operating temperature ranges

Procurement Notes

Verify the specific ordering suffix 'TQ100I' against official Microchip documentation to confirm the 100-pin TQFP package and Industrial temperature grade. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture before procurement.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed internal performance up to 350 MHz is required. Consider the 12,000 gate capacity and 81 available I/Os for moderate complexity designs. Verify that the 100-pin TQFP footprint fits the target PCB layout constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated on 0.22μm/0.25μm CMOS process technology. The family offers various gate counts and package options, with the A54SX08A representing the entry-level density option in the series.

Replacement Considerations

Check for other speed grades within the A54SX08A series or alternative packages like PQ208 if pin count allows. Verify functional equivalence with A54SX16A devices if additional logic resources are needed later.
