A42MX16-2PQ100I

Overview

The A42MX16-2PQ100I is a field-programmable gate array (FPGA) from the Microchip MX family, housed in a PQFP-100 package. It contains 295 configurable logic blocks and approximately 2000 system gates. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V. It features up to 83 user-programmable I/O pins and includes dual-port SRAM for fast access. The maximum clock frequency is 48.24 MHz, with a CLB delay of 3.72 ns. Operating temperatures range from -55°C to 125°C.

Feature Summary

• High-capacity single-chip ASIC alternative with deterministic timing
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/Os
• Integrated dual-port SRAM for high-speed data buffering
• Supports 100% resource utilization and pin locking

Applications

• Industrial control systems requiring wide temperature ranges
• Automotive electronics applications
• Military-grade embedded logic solutions
• PCI-compliant interface designs

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature grade (-55°C to 125°C) against official datasheets. Confirm package integrity for PQFP-100. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this model for designs needing moderate logic density with mixed-voltage compatibility. Ensure the 48.24 MHz speed grade meets timing constraints. Compare pin counts and I/O flexibility against other MX family members if more resources are needed.

Part Context

This component belongs to the Microchip A42MX16 series, part of the broader Actel/Microchip FPGA portfolio. It offers non-volatile flash-based configuration, eliminating the need for external memory. The series is known for low power consumption and radiation tolerance suitable for harsh environments.

Replacement Considerations

Check for direct pin-compatible upgrades within the A42MX16 series. Consider A42MX16 variants with different packages like VQG100 if board space allows. Verify functional equivalence with older A42MX09 series parts if migrating legacy designs.
