A42MX09-PQ144M

Overview

The A42MX09-PQ144M is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 336 Configurable Logic Blocks (CLBs), equivalent to 14,000 system gates, and provides 95 user-programmable I/O pins. The device operates with a core voltage of 4.75V to 5.25V and supports mixed-voltage I/O operation at 3.3V or 5.0V. It utilizes a 144-pin PQFP package and offers up to 2.5 kbits of configurable dual-port SRAM. The maximum clock frequency is 70.2 MHz with a CLB combinational delay of 3.5 ns.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, enabling compatibility with 3.3V and 5.0V systems while maintaining PCI-compliant I/O standards.
• Provides deterministic, user-controllable timing and allows up to 100% resource utilization and pin locking for precise design implementation.
• Includes unique in-system diagnostic and verification capabilities through Silicon Explorer II technology.

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status and check for relevant PCNs regarding manufacturing changes or obsolescence notices prior to procurement. Ensure storage conditions adhere to the specified moisture sensitivity level requirements.

Selection Notes

Select this model for designs requiring 14,000 system gates and mixed-voltage I/O support. Consider the 144-pin PQFP package constraints and verify that the 70.2 MHz performance meets timing requirements. Evaluate thermal management needs for the commercial temperature range specifications.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which are engineered to replace multiple PALs, CPLDs, and FPGAs on a single chip. The MX series focuses on cost-effective solutions for high-performance logic consolidation, offering significant gate density relative to its package size.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative gate counts or package types within the same family.
