A42MX16-2TQG176I

Overview

The A42MX16-2TQG176I is a field-programmable gate array from the Microchip MX series, housed in a 176-LQFP package. It provides 24,000 system gates and supports up to 140 I/O pins. The device operates on dual voltage supplies: 3V to 3.6V for the core and 4.5V to 5.5V for I/Os. It functions within an industrial temperature range of -40°C to +85°C. Key specifications include 608 logic elements and zero embedded memory bits.

Feature Summary

• Supports mixed-voltage operation with independent core and I/O power domains
• Provides deterministic timing through user-controllable constraints
• Enables high resource utilization with full pin locking capabilities

Applications

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

Procurement Notes

Verify the suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the 176-LQFP package dimensions match the design footprint. Check for RoHS compliance status and ensure the component is not subject to end-of-life notifications or recent manufacturing changes documented by the manufacturer.

Selection Notes

Select this model when 24K system gates and 140 I/Os are required in a 176-pin form factor. Ensure the design accommodates the separate 3V core and 5V I/O supply rails. Verify that the industrial temperature rating meets environmental requirements. Consider the lack of embedded memory if complex data buffering is needed.

Part Context

This part belongs to the Microchip MX FPGA family, which serves as a single-chip ASIC alternative. The series consolidates logic previously implemented in multiple PALs, CPLDs, and FPGAs. It offers high performance with fast wide-decode circuitry and configurable dual-port SRAM resources for flexible system integration.

Replacement Considerations

The A42MX16-2TQG176A is a commercial grade variant with identical electrical characteristics but a different temperature range (0°C to +70°C). Other packages in the A42MX16 series, such as PQG100 or CQ100, offer fewer I/Os and require retargeting.
