A42MX16-1VQG100I

Overview

The A42MX16-1VQG100I is a field-programmable gate array (FPGA) from the Microchip MX family, housed in a 100-pin VQFP package. It provides 608 logic elements and 24,000 system gates with 83 user-programmable I/O pins. The device operates at supply voltages of 3.3 V or 5.0 V, with a minimum voltage of 4.5 V and maximum of 5.5 V for 5V operation. It supports an industrial temperature range from -40°C to +85°C. Key performance metrics include a 5.6 ns clock-to-output delay and up to 250 MHz performance.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, enabling compatibility with 3.3 V and 5.0 V systems.
• Features deterministic, user-controllable timing and up to 100% resource utilization with pin locking capabilities.
• Includes configurable dual-port SRAM for fast data access and wide-decode circuitry for address decoding applications.

Applications

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

Procurement Notes

Verify the specific suffix '1' indicates the correct speed grade and that the 'I' suffix confirms the industrial temperature rating. Confirm the 100-VQFP package dimensions match your PCB footprint requirements. Check current RoHS compliance status as manufacturing sites may change over time.

Selection Notes

Select this model when a single-chip ASIC alternative is needed for designs requiring 24,000 system gates. Ensure the design utilizes the available 83 I/O pins effectively. Consider the 5.6 ns delay if high-frequency signal processing is required within the specified voltage ranges.

Part Context

This component belongs to the A42MX16 series, which offers high capacity and performance for complex logic consolidation. It serves as a drop-in replacement for multiple PALs, CPLDs, and FPGAs, reducing board space and simplifying development cycles for embedded logic applications.

Replacement Considerations

Compatible variants within the same package include A42MX16-PQG100I and A42MX16-VQG100A, though speed grades and temperature ratings must be verified against datasheet specifications before substitution.
