A54SX08A-FTQ100

Overview

The A54SX08A-FTQ100 is an SX-A family Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It features 12,000 system gates and 768 logic modules. The device operates with a standard speed grade and supports up to 81 user-programmable I/Os within a 100-pin Thin Quad Flat Pack (TQFP) package. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration. The part number suffix 'F' indicates a speed grade approximately 40% slower than the standard grade.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Includes dedicated clock networks with hardwired HCLK and routed CLKA/CLKB resources
• Provides IEEE 1149.1 compliant Boundary-Scan Testing via JTAG interface

Applications

• Low-power, high-performance embedded logic designs
• Systems requiring deterministic timing and pin-locking capabilities
• Applications needing mixed-voltage I/O operation (2.5 V, 3.3 V, and 5 V)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature range, and speed grade compatibility. Ensure that the selected variant meets the required environmental operating conditions and electrical specifications for the target application before finalizing procurement.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate external configuration memory. Consider the -F speed grade if lower performance is acceptable for cost or power optimization. Verify that the 100-pin TQFP package fits the PCB footprint constraints and that the 81 available I/Os satisfy the interface requirements.

Part Context

This device belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse-based nonvolatile technology. The family offers various capacity options ranging from 12,000 to 108,000 system gates. The A54SX08A represents the entry-level capacity in this series, providing a compact solution for simpler logic applications while maintaining the high-speed routing features of the larger devices.

Replacement Considerations

Direct replacements must match the 100-pin TQFP package and 12,000 gate capacity. Check for equivalent speed grades and temperature ranges. Note that other speed grades within the same package may offer different performance characteristics.
