A42MX16-PQ100

Overview

The A42MX16-PQ100 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin Plastic Quad Flat Package (PQFP). It provides approximately 24,000 system gates and 608 Logic Elements. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V, featuring up to 83 user-programmable I/O pins. Key performance metrics include a maximum clock frequency of 48.24 MHz and a CLB delay of 3.72 ns. It integrates configurable dual-port SRAM and fast wide-decode circuitry for high-capacity single-chip ASIC replacement.

Feature Summary

• High-density logic capacity suitable for replacing multiple discrete PALs, CPLDs, and FPGAs on a single chip
• Mixed-voltage operation capability supporting both 3.3V and 5.0V core and I/O configurations
• Integrated configurable dual-port SRAM for efficient data buffering and FIFO applications
• Deterministic timing characteristics with user-controllable delays and pin locking

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Industrial and military temperature environment logic control
• Automotive electronic system integration

Procurement Notes

Verify the specific suffix code against official datasheets to confirm voltage range and temperature grade. Standard commercial variants typically operate between -40°C and +85°C, while industrial or military grades extend to -55°C or +125°C. Confirm package authenticity as PQFP-100 and check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when designing systems requiring moderate logic density with deterministic timing constraints. Ensure the design utilizes the available 83 I/O pins within the 100-pin footprint limits. Verify that the target application voltage aligns with the 3.3V or 5.0V support capabilities. Consider the 24k gate count for complex state machines or interface bridging tasks.

Part Context

This part belongs to the Microsemi/Actel MX FPGA family, known for non-volatile flash-based technology. The A42MX16 variant specifically targets cost-effective ASIC alternatives. It consolidates logic functions previously handled by multiple programmable devices, reducing board space and power consumption in embedded control applications.

Replacement Considerations

Direct substitutes include other parts within the A42MX16 series with different suffixes indicating package or temperature variations, such as A42MX16-PQG100A or A42MX16-VQG100A. Cross-family replacements like the A40MX series may require significant schematic and firmware redesign due to architectural differences.
