A40MX04-3PLG44I

Overview

The A40MX04-3PLG44I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX series, designed for complex digital logic applications. It features 547 Configurable Logic Blocks (CLBs) and approximately 6000 system gates, providing substantial programmability within a compact footprint. The device supports dual voltage operation, accommodating both 3V (2.7V to 3.6V) and 5V (4.75V to 5.25V) power supplies, ensuring compatibility with various legacy and modern systems. It operates at a maximum clock frequency of 80 MHz with a CLB combinational delay of 2.7 ns. The component is housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads, suitable for surface-mount assembly. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports dual voltage operation for seamless integration into both 3V and 5V system architectures without external level shifting requirements.
• Features non-volatile flash-based technology that retains configuration data upon power loss, eliminating the need for external configuration memory devices.
• Provides robust security through multiple encryption options and password protection mechanisms to safeguard intellectual property within the design.

Applications

• Industrial control systems requiring deterministic logic timing and reliable operation in harsh environments.
• Automotive electronics applications needing low-power consumption and resistance to electromagnetic interference.
• Telecommunications infrastructure equipment utilizing high-speed serial communication protocols.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet, as commercial variants exist. Confirm the PLG44 package designation matches the required PCB footprint and lead form factor. Ensure compliance with current RoHS directives by checking the most recent manufacturer certification documents prior to procurement.

Selection Notes

Select this model when the design requires moderate logic density with established 5V or 3.3V I/O standards. Consider alternative packages if higher pin counts are necessary for complex interfaces. Evaluate power consumption requirements carefully, as SRAM-based FPGAs typically require external configuration memories, whereas this flash-based part integrates configuration storage directly on-chip.

Part Context

This component belongs to the Actel/Microchip MX family of flash-based FPGAs, known for instant-on capabilities and radiation tolerance. It serves as a successor to older EEPROM-based logic devices, offering greater speed and density while maintaining backward compatibility with many legacy designs. The MX series is widely used in aerospace, defense, and industrial sectors due to its proven reliability and long-term availability.

Replacement Considerations

Direct replacements include other variants within the A40MX04 family with different package options, such as A40MX04-PLG44I or A40MX04-VQG80, provided pin compatibility is verified. Cross-family migration to PolarFire or IGloo2 may be considered for enhanced performance but requires significant design re-verification.
