A42MX09-3PQ100I

Overview

The A42MX09-3PQ100I is a Field Programmable Gate Array from the Microchip Technology MX family, housed in a PQFP-100 package. It contains 684 logic cells and offers approximately 14,000 system gates. The device supports mixed-voltage operation with a core supply of 3.3V or 5V and I/Os compatible with both levels. Maximum operating frequency reaches 161 MHz with a CLB maximum combinational delay of 1.6 ns. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation for core and I/Os at 3.3V or 5.0V
• Provides deterministic, user-controllable timing characteristics
• Enables up to 100% resource utilization and pin locking

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage and speed grades. Confirm RoHS compliance status as some listings indicate non-compliance while others suggest lead-free variants exist. Check humidity sensitivity等级 and storage requirements before handling. Ensure the supplier provides valid traceability documentation for the PQFP-100 package type.

Selection Notes

Select this component when a single-chip ASIC alternative is required with high gate density. Consider the MX family for applications needing fast wide-decode circuitry and dual-port SRAM integration. Verify that the 161 MHz performance meets the target system clock requirements. Ensure the design utilizes the available 100 pins effectively for I/O expansion.

Part Context

This part belongs to the 40MX and 42MX FPGA families, designed as cost-effective solutions for consolidating logic previously implemented in multiple PALs, CPLDs, or FPGAs. The series is known for shortening system design cycles while maintaining high performance at 5V operation levels.

Replacement Considerations

The A42MX09-3PQG100I is a similar variant within the same family but uses a PQG (Plastic Quad Grid Array) package instead of PQFP. Pinout compatibility must be verified carefully due to the different physical footprint and connection method.
