A40MX04-PLG44M

Overview

The A40MX04-PLG44M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features approximately 6,000 system gates and 547 Logic Elements (LEs). The device operates with mixed-voltage support for both 3.3V and 5.0V core and I/O supplies, ensuring PCI-compliant interface capabilities. It is housed in a 44-pin PLCC package suitable for surface-mount installation. The component supports up to 202 user-programmable I/O pins within its architecture, offering deterministic timing and resource utilization flexibility for embedded logic applications.

Feature Summary

• Supports mixed-voltage operation allowing simultaneous 3.3V and 5.0V core and I/O configurations.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.
• Integrates fast wide-decode circuitry and configurable dual-port SRAM for efficient data handling.

Applications

• High-capacity single-chip ASIC replacement designs
• PCI-compliant interface implementations
• Embedded control logic requiring mixed-voltage I/O

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes military-grade qualification or a specific packaging variant, as standard commercial variants typically use suffixes like 'I' for industrial temperature range. Ensure the source document explicitly links this suffix to the part's electrical or environmental specifications before procurement.

Selection Notes

Select this model when a dense FPGA solution with mixed-voltage I/O compatibility is required. Compare the 44-pin PLCC footprint against other MX family members like the PLG68 or VQG80 if additional I/O count is needed. Confirm that the 6,000 gate capacity meets the design complexity without necessitating a larger package size.

Part Context

This component belongs to the A40MX04 series, which represents the mid-range density tier of the Actel/Microchip MX FPGA portfolio. It bridges the gap between lower-density CPLDs and higher-end FPGAs, offering non-volatile flash-based reprogrammability. The series is known for instant-on functionality and radiation tolerance options in specialized variants.

Replacement Considerations

Direct substitutes include other packages within the same A40MX04 family, such as A40MX04-PLG68 or A40MX04-VQ100, provided pin counts are sufficient. Cross-family replacements from Lattice or Altera require careful verification of I/O voltage levels and logic cell equivalence.
