A42MX09-1VQG100M

Overview

The A42MX09-1VQG100M is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Actel. It features 336 Logic Elements and approximately 14,000 system gates within a VQFP-100 package. The device operates with a minimum supply voltage of 4.5 V and a maximum of 5.5 V, supporting mixed-voltage I/O configurations at 3.3 V or 5.0 V. It functions reliably across an extended industrial temperature range from -55°C to +125°C. Key specifications include up to 83 user-programmable I/O pins and a maximum clock frequency of 70.2 MHz.

Feature Summary

• Flash-based non-volatile architecture enabling instant power-up operation without external configuration memory.
• Supports mixed-voltage I/O operation compatible with both 3.3 V and 5.0 V standards.
• Provides deterministic timing through user-controllable delay chains and wide-decode circuitry.
• Offers high resource utilization capabilities with full pin locking for robust design implementation.

Applications

• Replacement for complex ASICs in low-to-medium volume production environments.
• Industrial control systems requiring extended temperature stability and deterministic performance.
• Automotive electronics applications utilizing mixed-voltage logic interfaces.
• Military and aerospace systems requiring radiation-tolerant or high-reliability programmable logic solutions.

Procurement Notes

Verify the specific suffix '1' indicates the industrial/military temperature grade (-55°C to +125°C) rather than commercial variants. Confirm RoHS compliance status and export control classifications prior to ordering. Check for active manufacturing status as some MX series components may face end-of-life transitions. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when instant-on capability and radiation tolerance are required. Compare against A42MX16 if higher gate counts are needed. Verify that the VQFP-100 package fits the PCB footprint constraints. Ensure the 70.2 MHz speed grade meets the target application's timing requirements. Consider the 336 LE capacity for logic density needs versus larger family members.

Part Context

This part belongs to the A42MX09 series, representing the lower-density tier of the Actel MX FPGA family. It shares architectural similarities with the A40MX and A54SX series but offers distinct Flash technology advantages. The VQG100 suffix denotes the 100-pin Very Thin Quad Flat Package variant optimized for surface-mount assembly.

Replacement Considerations

Direct substitutes include other A42MX09 variants with different packages such as FPQG100I. Cross-family replacements like A42MX16 offer increased resources but require design re-validation. Legacy Actel parts may be sourced through authorized distributors ensuring authenticity.
