A40MX04-PLG44

Overview

The A40MX04-PLG44 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, featuring 6,000 system gates and 547 logic elements. It operates with a supply voltage range of 4.5 V to 5.5 V and supports I/O voltages of 3.3 V and 5 V. The device provides 34 input/output pins housed in a PLCC-44 package. It functions within an operating temperature range of -40°C to +85°C for industrial applications. Key specifications include a maximum clock frequency of 80 MHz and a CLB-max combinatorial delay of 2.7 ns. The component has no embedded memory and carries a Moisture Sensitivity Level (MSL) rating of 3.

Feature Summary

• Supports dual voltage operation at 3.3 V and 5 V for flexible interface compatibility
• Industrial temperature range capability for extended environmental reliability
• Non-volatile flash-based architecture for instant-on functionality

Applications

• Industrial control systems requiring robust programmable logic
• Embedded interfaces for legacy 5V digital circuits
• Automotive electronics operating under strict thermal conditions

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure ESD precautions are followed during handling due to moisture sensitivity level 3 classification. Confirm RoHS compliance status through current manufacturer documentation before integration into production assemblies.

Selection Notes

Select this model when a compact 44-pin solution is required for moderate logic density. Verify that the 34 available I/O pins meet the interface requirements of the target design. Consider the 80 MHz performance limit for timing-critical applications within the specified voltage constraints.

Part Context

This component belongs to the A40MX04 family, which shares core architectural features such as gate count and logic structure. Variants within this family differ primarily by package style, pin count, and operating temperature ranges. The PLG44 designation specifically identifies the plastic leaded chip carrier package configuration.

Replacement Considerations

Direct replacements include other variants within the A40MX04 series, such as the A40MX04-1PLG44 or A40MX04-VQG80, provided pinout and package dimensions match the existing board layout. Cross-series migration requires careful verification of logic element counts and I/O configurations.
