A54SX32A-1TQG100

Overview

The A54SX32A-1TQG100 is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 1,452 logic modules. It operates at a maximum frequency of 278 MHz with a 2.5 V supply voltage range of 2.25 V to 2.75 V. The device provides 81 user-programmable I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package. It utilizes 0.22 μm/0.25 μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)
• Provides deterministic timing with up to 100% resource utilization and pin locking

Applications

• 66 MHz PCI compliant single-chip solutions
• Low-power high-performance designs requiring nonvolatile configuration
• Systems requiring mixed-voltage I/O interfacing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Confirm availability status as product lifecycles may change.

Selection Notes

Select this model when 48,000 system gates and 81 I/Os are required in a compact 100-pin TQFP footprint. The -1 speed grade offers approximately 15% faster performance than standard speed. Verify that the commercial temperature range (0°C to +70°C) aligns with your application environment.

Part Context

This component belongs to the Actel SX-A FPGA family, which uses antifuse technology for permanent, nonvolatile programming. The SX-A series is designed to replace multiple CPLDs or gate arrays in high-performance applications, offering low power consumption and fast signal propagation through its unique metal-to-metal interconnect architecture.
