A42MX16-PQ100M

Overview

The A42MX16-PQ100M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 2,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V, ensuring PCI-compliant compatibility. Key performance metrics include a maximum clock frequency of 48.24 MHz and a CLB delay of 3.72 ns. It offers up to 2.5 kbits of configurable dual-port SRAM and supports up to 100 user-programmable I/O pins in a PQFP-100 package.

Feature Summary

• Provides deterministic, user-controllable timing for precise design implementation.
• Supports up to 100% resource utilization and complete pin locking capabilities.
• Enables unique in-system diagnostic and verification through Silicon Explorer II.
• Facilitates mixed-voltage operation with PCI-compliant I/O standards.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces and DSP functions
• Co-processor implementations and ASIC prototyping

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm military-grade temperature ratings and qualification status. Ensure the ordering part number matches the required package variant and voltage specifications. Cross-reference the manufacturer's latest datasheet for any recent product change notices affecting this component.

Selection Notes

Select this model when a cost-effective FPGA solution with mixed-voltage support is required. It serves as a direct replacement for multiple PALs, CPLDs, and FPGAs. Consider the 2.5 kbits of embedded SRAM for data buffering needs. Verify that the 100-pin QFP package fits the target board layout constraints.
