A42MX16-1VQ100

Overview

The A42MX16-1VQ100 is a field-programmable gate array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 608 logic elements and approximately 24,000 system gates within a 100-pin VQFP package. The device supports mixed-voltage operation with supply ranges of 3V to 3.6V for the core and 4.5V to 5.5V for I/Os. It operates at a maximum clock frequency of 135 MHz and functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports mixed-voltage operation allowing independent core and I/O power supplies.
• Provides high-density programmable logic suitable for ASIC replacement applications.
• Features deterministic timing with user-controllable constraints.

Applications

• High-capacity single-chip ASIC alternatives
• Industrial control systems requiring wide temperature tolerance
• Automotive electronics interfaces

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage and temperature grades. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for recent product change notifications regarding assembly sites or software updates.

Selection Notes

Compare logic element counts and I/O availability against design requirements. Ensure the selected package fits the PCB footprint constraints. Verify that the required operating temperature range matches the specific suffix designation for commercial or industrial use.

Part Context

This component belongs to the Actel/Microchip MX family of flash-based FPGAs. These devices are designed for low-power, high-reliability applications where non-volatile configuration is essential. The family offers a balance of performance and density for embedded logic control tasks.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the A42MX16 series with different speed grades or packages. Verify functional equivalence in terms of logic resources and I/O standards before substitution.
