A42MX09-PQ100A

Overview

The A42MX09-PQ100A is a Field Programmable Gate Array (FPGA) belonging to the Microchip Technology 42MX family. It features 336 Configurable Logic Blocks (CLBs), providing approximately 14,000 system gates and 684 logic cells. The device supports up to 104 user-programmable I/O pins within a 100-pin Plastic Quad Flat Package (PQFP). Electrical specifications include a maximum clock frequency of 70.2 MHz and a CLB maximum combinational delay of 3.5 ns. It operates with mixed-voltage capabilities, supporting both 3.3V and 5.0V core and I/O supplies. The component is available in industrial temperature ranges, typically spanning from -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative offering high capacity with up to 54,000 system gates across the family.
• Integrates up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.
• Supports mixed-voltage operation allowing flexible 3.3V or 5.0V core and I/O configurations.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Replacement for legacy PALs, CPLDs, and FPGAs in consolidated designs

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact package type and temperature grade. Ensure compatibility with existing PCB footprints for PQFP-100 assemblies. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process before procurement.

Selection Notes

Select this model when 14,000 system gates and 104 I/Os are sufficient for the design. Consider the 70.2 MHz performance limit for timing closure. Evaluate the need for mixed-voltage I/O support if interfacing with both 3.3V and 5V peripherals. Compare against higher-density 42MX variants if additional logic resources are required.

Part Context

This component is part of the broader 40MX and 42MX FPGA families originally developed by Actel and acquired by Microchip Technology. These devices are designed as cost-effective solutions for replacing complex discrete logic. The 42MX series specifically targets applications requiring high performance and mixed-voltage integration in plastic packages.

Replacement Considerations

Direct functional equivalents within the same density class may include other A42MX09 variants with different package options such as FPQG100 or PL208I. Verify pinout compatibility and thermal characteristics when substituting between package types like PQFP and QFP.
