A42MX09-1PQG100M

Overview

The A42MX09-1PQG100M is a Field Programmable Gate Array (FPGA) from the Microchip MX series, originally developed by Actel. It features 336 Configurable Logic Blocks (CLBs), equivalent to 14,000 system gates, and supports up to 104 user-programmable I/O pins. The device operates with a core voltage of 3.3V or an I/O supply of 5.0V/3.3V, ensuring mixed-voltage compatibility. It is housed in a 100-pin Plastic Quad Flat Package (PQFP). The maximum clock frequency reaches 70.2 MHz, with a CLB combinational delay of 3.5 ns. Operating temperatures range from -40°C to +85°C for industrial applications.

Feature Summary

• Single-chip ASIC alternative offering high capacity logic resources
• Mixed-voltage operation supporting both 5.0V and 3.3V I/O supplies
• Deterministic timing with user-controllable delays
• Supports 100% resource utilization and pin locking

Applications

• Industrial control systems requiring deterministic logic
• Automotive electronics interfaces
• Military and aerospace embedded applications
• Replacement for complex discrete logic circuits

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a military-grade qualification or specific packaging variant, as standard commercial variants typically use suffixes like 'I'. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for legacy Actel-derived parts may vary.

Selection Notes

Select this component when a non-volatile FPGA solution with mixed-voltage I/O capability is required. Ensure the design utilizes the 100-pin PQFP footprint. Verify that the 14,000 gate count and 336 CLBs meet the logic density requirements. Check if the 70.2 MHz speed grade satisfies the timing constraints of the target application.

Part Context

This part belongs to the A42MX09 family, which represents a transition period where Actel's technology was integrated into Microchip's portfolio following the acquisition. These devices are known for their flash-based non-volatile architecture, eliminating the need for external configuration memory commonly found in SRAM-based FPGAs.

Replacement Considerations

Direct replacements include other members of the A42MX09 family such as A42MX09-PQG100 or A42MX09-FPQG100I, provided the temperature grade and package match. For higher capacity needs within the same architecture, consider the A42MX16 series.
