A42MX16-VQG100I

Overview

The A42MX16-VQG100I is a field-programmable gate array from the Microchip MX family, housed in a 100-pin VQFP package. It provides 608 logic elements and supports up to 83 user-programmable I/O pins. The device operates within a supply voltage range of 4.5 V to 5.5 V and functions reliably across an industrial temperature range of -40°C to +85°C. This FPGA serves as a high-capacity single-chip ASIC alternative with deterministic timing.

Feature Summary

• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Enables up to 100% resource utilization and pin locking for design flexibility
• Provides unique in-system diagnostic and verification capabilities via Silicon Explorer II

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix 'VQG100I' against official Microchip documentation to confirm the exact package type and industrial temperature rating. Ensure compatibility with existing PCB footprints for the 100-pin VQFP form factor before procurement.

Selection Notes

Select this component when a cost-effective single-chip solution is required to consolidate logic previously implemented in multiple PALs or CPLDs. Consider the MX family's high performance and wide-decode circuitry for applications demanding deterministic timing and mixed-voltage I/O support.

Part Context

This part belongs to the A42MX16 series within the broader MX FPGA family. It shares architectural features with other variants like the A42MX16-2VQG100I but differs in speed grade and operating temperature specifications defined by its suffix codes.

Replacement Considerations

Direct substitutes include other A42MX16 variants such as A42MX16-2VQG100I or A42MX16-VQG100A, provided the speed grade and temperature range requirements align with the application design constraints.
