A42MX16-2PQG100I

Overview

The A42MX16-2PQG100I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Actel. It features 24,000 system gates and 608 Logic Elements. The device provides 83 programmable I/O pins and operates within a supply voltage range of 3 V to 5.5 V. It supports a maximum operating temperature of +85°C and a minimum of -40°C. The component is housed in a PQFP-100 surface-mount package with a typical delay time of 2.1 ns.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Supports mixed-voltage operation for both core and I/Os, including PCI-compliant interfaces
• Enables up to 100% resource utilization and pin locking for deterministic timing
• Includes unique in-system diagnostic and verification capabilities via Silicon Explorer II

Applications

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

Procurement Notes

Verify the specific suffix '2' indicates the speed grade when sourcing replacements. Confirm RoHS compliance status through official Microchip documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the PQFP-100 package footprint matches the target PCB design. Validate that the industrial temperature range meets the operational environment specifications.

Selection Notes

Select this model for designs requiring a cost-effective solution at 5V with high performance. Consider the 24K gate capacity for consolidating complex logic functions. Evaluate the 83 I/O count against interface requirements. Compare the 2.1 ns delay against system timing constraints. Verify compatibility with existing development tools like Silicon Explorer II.

Part Context

This component belongs to the A42MX family, which offers single-chip solutions for high-performance applications. The MX series is designed to shorten system design cycles by replacing multiple discrete logic devices. It serves as a bridge between traditional PLDs and more complex FPGAs, offering flexibility for various industrial and commercial uses.

Replacement Considerations

Direct substitutes include other variants within the A42MX16 series with different packages or speed grades, such as A42MX16-PQG100I. Cross-reference pinouts and electrical characteristics carefully. Ensure the replacement maintains the same logic density and I/O configuration.
