A54SX08A-TQG100I

Overview

The A54SX08A-TQG100I is a Field Programmable Gate Array (FPGA) from the Microchip SX-A family, featuring 12,000 system gates and 768 logic modules. It provides 81 user-programmable I/Os within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates at an industrial temperature range of -40°C to +85°C and utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. It supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance.

Feature Summary

• Supports hot-swappable I/O configurations for safe insertion into active systems without power sequencing requirements.
• Features nonvolatile single-chip architecture that eliminates configuration bitstreams and prevents reverse engineering via FuseLock technology.
• Includes deterministic timing capabilities with DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• Industrial control systems requiring deterministic performance and robust I/O standards
• Embedded processing applications utilizing the high-performance internal clock networks
• Secure hardware designs necessitating protection against unauthorized design access

Procurement Notes

Verify the specific ordering suffix 'G' if RoHS compliant packaging is required, as standard packaging may differ. Confirm the lead count matches the 100-pin TQFP specification. Ensure the temperature grade corresponds to the Industrial (-40°C to +85°C) requirement for the target environment. Cross-reference the datasheet revision to confirm current availability status.

Selection Notes

Select this model for designs requiring approximately 12,000 system gates with 81 available I/O pins. The Industrial temperature grade ensures reliable operation in harsh environments. Consider the 0.22 μm process technology for low-power consumption. Verify that the 100-pin TQFP package fits the PCB footprint constraints and thermal management requirements of the application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect elements. The family offers various capacity options ranging from 12,000 to 108,000 system gates. The SX-A architecture is designed for high-speed applications with up to 350 MHz internal performance and supports multiple voltage levels for flexible I/O integration.

Replacement Considerations

Compatible alternatives within the same family include the A54SX08A-1PQ208I, which offers the same gate count but in a 208-pin PQFP package. Other speed grades such as A54SX08A-2TQG100I provide faster performance. For higher capacity needs, the A54SX16A series serves as a scalable option with increased logic resources.
