A42MX16-WAFERLOT

Overview

The A42MX16-WAFERLOT is a wafer-level version of the MX series Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. This component provides 608 Logic Elements and approximately 24,000 system gates for custom ASIC replacement applications. It supports mixed-voltage operation with supply ranges of 3V to 3.6V or 4.5V to 5.5V. The device operates across an extended temperature range from -55°C to 125°C, suitable for commercial, industrial, automotive, and military environments.

Feature Summary

• Provides high-capacity single-chip ASIC alternative functionality using flash-based FPGA technology
• Supports mixed-voltage I/O operation compatible with both 5.0V and 3.3V standards
• Enables deterministic timing with user-controllable delay elements and pin locking capabilities

Applications

• Custom ASIC prototyping and low-volume production replacements
• Military and aerospace electronic systems requiring extended temperature tolerance
• Automotive embedded control applications
• Industrial automation logic implementation

Procurement Notes

Verify that the procurement channel supplies genuine Microchip Technology wafers rather than third-party substrates. Confirm that the specific lot number matches the required voltage and temperature grade specifications. Ensure handling procedures comply with electrostatic discharge protocols appropriate for bare die or wafer-level components during integration into final packaging.

Selection Notes

Select this variant when standard packaged FPGAs are unavailable or when custom assembly processes require wafer-level sourcing. Consider the need for external packaging and testing infrastructure. Evaluate if the 608 Logic Element capacity meets the design complexity requirements compared to higher-density MX family members.

Part Context

This part belongs to the Microchip A42MX16 family, which utilizes non-volatile flash technology for instant-on configuration. The family offers up to 54,000 system gates and includes configurable dual-port SRAM blocks. The WAFERLOT designation indicates the component is supplied as raw silicon wafers for specialized manufacturing integration.

Replacement Considerations

Public confirmed substitute part numbers are not available for this wafer-level variant. Standard packaged equivalents such as A42MX16-1TQG100A or A42MX16-PQG100I may serve as functional replacements if packaging differences are acceptable.
