A42MX36-2PQG208I

Overview

The A42MX36-2PQG208I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 208-pin PQFP package. It features 2438 Configurable Logic Blocks (CLBs) and approximately 36,000 equivalent system gates. The device supports a maximum clock frequency of 99 MHz with a CLB maximum combinational delay of 2.1 ns. It operates within a supply voltage range of 3V to 3.6V for the core and 4.75V to 5.25V for I/Os. The industrial temperature grade ensures reliable operation between -40°C and +85°C.

Feature Summary

• Provides single-chip ASIC alternative capabilities with up to 2.5 kbits of configurable dual-port SRAM.
• Supports mixed-voltage operation allowing 5.0V or 3.3V configurations for both core and I/Os.
• Enables deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP functions
• Co-processor functions and complex logic consolidation

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential counterfeits. Confirm RoHS compliance status as manufacturing sites may vary. Check for End-of-Life (EOL) notices or Production Change Notices (PCN) affecting availability. Ensure proper ESD handling during storage and installation. Validate that the specific suffix matches required environmental and speed grades.

Selection Notes

Select this model when 36,000 system gates and 99 MHz performance are required in a PQFP-208 package. Choose the 'I' suffix for industrial temperature range (-40°C to +85°C). Consider the '2' speed grade for the 2.1 ns CLB delay specification. Verify power supply requirements for mixed 3.3V and 5.0V operation before integration into the design.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, designed as cost-effective solutions for 5V applications. These devices consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. The MX series is known for high performance and shortened development cycles, serving as a direct replacement for legacy programmable logic devices in various industrial and commercial applications.

Replacement Considerations

Direct pin-compatible replacements within the same package and gate count are limited. Evaluate A42MX36 variants with different speed grades (e.g., -1 for higher performance) or temperature ranges (e.g., -B for automotive/broad industrial). Cross-family migration to newer Microchip PolarFire or SmartFusion2 families may be necessary for long-term supply assurance, requiring schematic and layout redesign.
