A42MX09-2PQ100I

Overview

The A42MX09-2PQ100I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 336 Configurable Logic Blocks (CLBs), providing approximately 14,000 system gates and 684 logic elements. The device supports mixed-voltage operation with core and I/O supplies of either 3.3V or 5.0V, ensuring PCI-compliant interfacing capabilities. It operates within a commercial temperature range of -40°C to +85°C and is housed in a 100-pin Plastic Quad Flat Package (PQFP). Key performance metrics include a maximum clock frequency of up to 70.2 MHz and a CLB maximum combinatorial delay of 3.5 ns.

Feature Summary

• Supports mixed-voltage operation for both core and I/O supplies at 3.3V or 5.0V, enabling direct interface with PCI-compliant peripherals without level shifting.
• Offers deterministic, user-controllable timing through 100% resource utilization and pin locking capabilities, facilitating precise signal path management.
• Provides fast wide-decode circuitry and configurable dual-port SRAM to enhance processing speed and data handling efficiency.

Applications

• Replacement for complex discrete logic or standard ASICs in embedded control systems
• Interface bridging between legacy 5V components and modern 3.3V digital systems
• Prototyping and low-volume production of custom digital logic circuits

Procurement Notes

Verify the specific suffix '2' against official Microchip documentation to confirm the exact speed grade and operating temperature range, as variations exist within the A42MX09 family. Confirm RoHS compliance status, as older revisions may differ from current manufacturing standards. Ensure ESD precautions are taken during handling due to moisture sensitivity classification. Cross-reference the package outline dimensions with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a moderate gate count (~14K) is required with flexible voltage levels. Compare against the A42MX09-PQ100I if a different speed bin is needed. Consider the A42MX16 or A42MX24 if higher logic density or additional I/O pins are necessary for future scalability. Evaluate the PQFP-100 package constraints against available board space and thermal dissipation requirements relative to other surface-mount options.

Part Context

This part belongs to the Actel MX FPGA family, originally developed by Actel and now maintained by Microchip Technology following acquisitions. The MX series is renowned for its non-volatile Flash-based architecture, which eliminates the need for external configuration memory. This specific model represents a mid-range density option within the 09-series, balancing logic capacity with power efficiency for industrial and commercial applications.

Replacement Considerations

Direct functional substitutes include other variants within the A42MX09 family such as the A42MX09-PQ100I, provided speed grades align. For higher density needs, the A42MX16 or A42MX24 series may serve as upward-compatible alternatives, though pin counts and resources will differ. No direct cross-brand equivalents exist due to the proprietary Flash FPGA architecture.
