A42MX16-3VQG100I

Overview

The A42MX16-3VQG100I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 24,000 system gates and 608 Logic Elements within a 100-pin VQFP package. The device supports mixed-voltage operation with core voltages of 3.3V or 5.0V and includes up to 2.5 kbits of configurable dual-port SRAM. It offers 83 user-programmable I/O pins, deterministic timing, and operates across industrial temperature ranges.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, ensuring PCI compliance.

Applications

• High-speed controllers
• Address decoding
• Peripheral bus interfaces

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm voltage range and temperature grade, as standard variants typically use '2'. Confirm RoHS status and MSL rating before ordering. Check for active production status and lead times directly with Microchip Technology distributors.

Selection Notes

Select this component for designs requiring deterministic timing and pin locking capabilities. Ensure the 100-pin VQFP package fits the PCB layout constraints. Verify that the 24K gate count and 2.5 kbit SRAM meet the logic density requirements compared to lower-density CPLDs.

Part Context

This part belongs to the A42MX16 series, which provides a cost-effective solution for replacing multiple PALs, CPLDs, and FPGAs. The MX family is known for its fast wide-decode circuitry and high performance, suitable for consolidating complex logic functions into a single chip.

Replacement Considerations

Direct substitutes include other A42MX16 variants with different suffixes for package or temperature, such as A42MX16-2VQG100I. Cross-family replacements may require logic restructuring due to differences in gate counts and SRAM availability.
