A42MX09-PQ100I

Overview

The A42MX09-PQ100I is a Field Programmable Gate Array (FPGA) from the MX family, manufactured by Microchip Technology. It features 336 Configurable Logic Blocks (CLBs), providing approximately 14,000 system gates and 684 logic cells. The device operates with a maximum clock frequency of 70.2 MHz and exhibits a CLB maximum combinatorial delay of 3.5 ns. It supports mixed-voltage operation for both core and I/O supplies at 3.3V or 5.0V. The component is housed in a 100-pin Plastic Quad Flat Package (PQFP-100) and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative offering high capacity with up to 14,000 system gates
• Supports mixed-voltage operation with PCI-compliant I/Os for flexible integration
• Includes up to 2.5 kbits of configurable dual-port SRAM for data storage
• Provides deterministic, user-controllable timing with up to 100% pin locking

Applications

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

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm package integrity for the PQFP-100 form factor. Check current lifecycle status as legacy components may have limited availability. Ensure RoHS compliance matches project requirements. Validate supply chain authenticity through authorized distributors.

Selection Notes

Select this model when 14,000 system gates and 100 I/O pins are required in a compact PQFP package. Compare against higher-performance variants like the A42MX09-3PQ100I if speeds exceeding 70 MHz are needed. Consider the A42MX09-FPQG100I for similar gate counts but verify pin compatibility differences between standard and fine-pitch packages.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are designed to replace multiple PALs, CPLDs, and FPGAs in a single chip. The MX series emphasizes ease of integration and cost-effective design solutions for 5V applications, bridging the gap between simple programmable logic and complex FPGAs.

Replacement Considerations

The A42MX09-3PQ100I offers higher performance (161 MHz) within the same PQFP-100 package. The A42MX09-FPQG100I provides similar logic density but requires verification of fine-pinch vs. standard pitch compatibility.
