A42MX16-TQG176I

Overview

The A42MX16-TQG176I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features approximately 24,000 system gates and 608 Logic Elements within a 176-pin TQFP package. The device supports mixed-voltage operation with core supplies ranging from 3V to 3.6V and I/O supplies from 4.5V to 5.5V. It offers up to 140 user-programmable I/O pins and includes configurable dual-port SRAM for data storage. Operating temperatures extend from -40°C to +85°C for industrial applications.

Feature Summary

• Provides high-density programmable logic with fast wide-decode circuitry for complex address decoding and control functions.
• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5V components on the same board.
• Includes configurable dual-port SRAM to facilitate high-speed FIFO operations and data buffering.
• Enables deterministic timing through 100% pin locking and resource utilization capabilities.

Applications

• High-speed controllers and peripheral bus interfaces
• Address decoding and logic consolidation replacing multiple PALs or CPLDs
• DSP and co-processor functions in embedded systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm voltage ranges and temperature grades. Ensure the ordering part number matches the required package type and speed grade. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement to meet manufacturing standards.

Selection Notes

Select this component when designing systems requiring significant logic density in a surface-mount package. Consider the mixed-voltage capability if interfacing with legacy 5V peripherals. Verify that the 176-pin footprint fits the PCB layout constraints and that the thermal performance meets the operational environment requirements.

Part Context

This device belongs to the A42MX family, which serves as a cost-effective solution for consolidating logic previously implemented in multiple discrete devices. The MX series is known for shortening design cycles by integrating high-performance logic and memory on a single chip, suitable for replacing older programmable logic technologies.

Replacement Considerations

Check for updated suffixes such as 'A' or 'M' which may indicate different speed grades or environmental certifications. Review Product Change Notices (PCN) for any packaging or material updates that might affect compatibility with existing assembly processes.
