A42MX16-VQ100A

Overview

The A42MX16-VQ100A is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 2,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of either 3.3V or 5.0V, ensuring PCI-compliant compatibility. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The component operates within a temperature range of -40°C to +125°C and utilizes a 100-pin VQFP package.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os at 3.3V or 5.0V levels
• Includes configurable dual-port SRAM for embedded memory applications
• Features deterministic, user-controllable timing with pin locking capabilities
• Provides unique in-system diagnostic and verification capability

Applications

• Single-chip ASIC replacement designs
• Mixed-voltage interface logic
• Industrial control systems
• Military-grade electronic assemblies

Procurement Notes

Verify the exact suffix against official Microchip documentation, as standard listings typically use VQG100A for this package type. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the specific revision matches your design requirements. Check for any recent Product Change Notifications regarding assembly sites or material updates.

Selection Notes

Select this model for designs requiring moderate logic density with robust I/O flexibility. The VQFP-100 package offers surface-mount convenience. Consider the 3.3V or 5.0V core options based on system power constraints. Verify that the 295 CLB count meets the complexity needs of the target application before finalizing the part number.

Part Context

This component belongs to the A42MX series, which provides high-density programmable logic in plastic packages. The series is known for supporting commercial, industrial, and military temperature ranges. It serves as a bridge between standard CPLDs and larger FPGAs, offering significant gate counts in compact footprints suitable for space-constrained boards.

Replacement Considerations

Direct substitutes include other variants within the A42MX16 family, such as the A42MX16-VQG100A, which shares identical electrical characteristics but may differ in package tolerance or testing standards. Cross-family replacements require careful evaluation of logic block counts and I/O configurations.
