A42MX09-PQG100M

Overview

The A42MX09-PQG100M is a Field Programmable Gate Array (FPGA) from the MX series, manufactured by Microchip Technology. It features 336 Configurable Logic Blocks (CLBs), 684 Logic Elements, and an equivalent of 14,000 system gates. The device supports up to 104 user-programmable I/O pins and operates within a voltage range of 4.75 V to 5.25 V for the core, with mixed-voltage capability allowing 3.3 V or 5.0 V I/O supplies. It is housed in a PQFP-100 plastic package and functions reliably across a temperature range of -40 °C to +85 °C.

Feature Summary

• Single-chip ASIC alternative offering high capacity logic resources
• Mixed-voltage operation supporting both 5.0V and 3.3V I/O standards
• PCI-compliant I/Os with deterministic, user-controllable timing
• Supports 100% resource utilization and pin locking

Applications

• Industrial control systems requiring mixed-voltage interfaces
• Automotive electronics applications
• Military and aerospace embedded processing
• General-purpose programmable logic prototyping

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 listings may not explicitly detail this suffix's functional impact. Ensure compliance with RoHS directives and check for any End-of-Life notifications or Production Change Notices relevant to the manufacturing site.

Selection Notes

Select this component when a dense logic array in a QFP package is required without BGA reflow constraints. Compare against the A42MX09-FPQG100I for industrial temperature ranges or the A42MX09-3PQ100I for higher speed grades. Consider the available SRAM configuration and I/O count relative to the target interface requirements.

Part Context

This part belongs to the Actel/Microchip MX FPGA family, known for non-volatile flash-based technology that eliminates the need for external configuration memory. The A42MX09 variant represents a mid-range density option within the broader 42MX portfolio, bridging lower-density parts like the A42MX06 and higher-density devices such as the A42MX16.

Replacement Considerations

Direct pin-compatible replacements include other variants within the A42MX09 series, such as A42MX09-FPQG100I or A42MX09-2PG100A, depending on required temperature and speed grades. Cross-series migration to A42MX16 requires schematic review due to increased I/O counts.
