A42MX16-1TQG176I

Overview

The A42MX16-1TQG176I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 24,000 system gates and supports up to 140 user-programmable I/O pins within a 176-LQFP package. The device operates with dual voltage supplies: 3V to 3.6V for the core and 4.5V to 5.5V for I/Os. It includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry. The industrial temperature grade ensures reliable operation across a range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation allowing independent control of core and I/O supply voltages.
• Provides deterministic timing with user-controllable delays and pin locking capabilities.
• Integrates configurable dual-port SRAM for flexible memory management.

Applications

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

Procurement Notes

Verify the specific suffix '1' indicates the industrial temperature grade (-40°C to +85°C) distinct from commercial variants. Confirm the 176-TQFP package dimensions match the design footprint. Check for RoHS compliance status and ensure the ordering quantity aligns with manufacturer tray specifications.

Selection Notes

Select this model when an industrial temperature rating is required alongside high I/O density. Compare against the A42MX16-2TQG176I if extended temperature ranges or different speed grades are needed. Ensure the 176-pin LQFP form factor fits the PCB constraints before finalizing the component choice.

Part Context

This part belongs to the Microchip A42MX16 family, which consolidates logic previously implemented in multiple PALs, CPLDs, and FPGAs. The MX series is known for providing cost-effective solutions with high performance, enabling shorter system design cycles while maintaining compatibility with legacy designs.

Replacement Considerations

The A42MX16-2TQG176I is a verified substitute offering similar functionality but potentially differing in speed grade or temperature classification. Verify pinout compatibility and electrical characteristics before swapping components in existing hardware designs.
