A40MX04-1PLG68I

Overview

The A40MX04-1PLG68I is a field-programmable gate array from the Microchip MX series, featuring approximately 6,000 system gates and 547 logic elements. It provides 57 input/output pins within a 68-pin PLCC package. The device operates on dual voltage supplies of 3.3 V and 5 V, with specified ranges of 4.5 V to 5.5 V for the 5 V supply. It supports surface-mount installation and functions within an industrial temperature range of -40°C to +85°C. The component includes moisture sensitivity classification and complies with RoHS standards.

Feature Summary

• Supports non-volatile flash-based FPGA architecture for instant-on functionality without external configuration memory.
• Integrates high-density programmable logic blocks suitable for complex digital design implementations.
• Offers flexible I/O configurations compatible with multiple voltage standards for diverse interface requirements.

Applications

• Industrial control systems requiring reliable programmable logic in harsh environments.
• Automotive electronics applications utilizing robust FPGA architectures.
• Telecommunications infrastructure equipment needing flexible signal processing capabilities.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the 68-PLCC package dimensions match the target PCB footprint. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when an industrial temperature range is required alongside a 68-pin PLCC package. Compare pin counts and gate density against other MX series variants if fewer I/Os suffice. Consider the 3.3V/5V dual supply capability for compatibility with existing system power rails. Evaluate alternative packages like VQFP or PQFP if board space constraints differ significantly.

Part Context

This component belongs to the Actel (now Microchip) MX family of flash FPGAs. These devices are known for their non-volatile configuration storage, eliminating the need for boot PROMs. The A40MX04 variant represents a mid-range density option within this lineage, balancing logic capacity with pin count for general-purpose programmable logic applications.

Replacement Considerations

Direct substitutes include other A40MX04 variants with different packages such as A40MX04-VQG80I or A40MX04-3PLG84I, provided pin compatibility and thermal grades align with the design requirements. Verify that any replacement maintains the same logic element count and I/O availability.
