A42MX09-PQG160I

Overview

The A42MX09-PQG160I is a non-volatile Flash FPGA from the Microchip MX series, manufactured by Microchip Technology. It features 14,000 system gates and 336 Configurable Logic Blocks (CLBs) within a 160-pin Plastic Quad Flat Package (PQFP). The device supports mixed-voltage operation with core supply voltages ranging from 3V to 3.6V and I/O supply voltages from 4.75V to 5.25V. It offers 101 user-programmable I/O pins and operates within a commercial temperature range of 0°C to 70°C. The component utilizes CMOS technology and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.

Feature Summary

• Non-volatile Flash-based architecture enabling instant-on functionality without external configuration memory.
• Mixed-voltage capability supporting both 3.3V and 5.0V I/O interfaces for flexible system integration.
• Deterministic timing characteristics with user-controllable delays and pin locking capabilities.
• High-density logic resources providing up to 100% resource utilization for complex digital designs.

Applications

• Single-chip ASIC replacement for low-to-medium volume production runs.
• Industrial control systems requiring deterministic timing and mixed-voltage interfacing.
• Automotive electronics operating within commercial temperature ranges.
• Military and aerospace applications utilizing qualified ceramic or plastic packages.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial or commercial temperature rating as defined in the official datasheet. Confirm RoHS compliance status, as historical batches may vary. Check for Product Change Notifications (PCN) regarding assembly sites or software updates. Ensure the 160-PQFP package dimensions match the target PCB footprint. Validate that the non-volatile Flash nature meets the power-up requirements of the final application.

Selection Notes

Select this model when a non-volatile FPGA solution is required to eliminate external configuration EEPROMs. Compare gate counts against the A42MX16 or A42MX24 if higher logic density is needed. Verify voltage levels match the 3.3V core and 5.0V I/O specifications. Consider the 160-pin PQFP package constraints versus smaller QFN or larger TQFP options available in the same family. Ensure the design fits within the 336 CLB and 2.5 kbit SRAM limits.

Part Context

This component belongs to the Actel MX family, now managed by Microchip Technology following their acquisition. The MX series is distinguished by its non-volatile Flash process, which allows the FPGA to retain configuration data without power. This contrasts with volatile SRAM-based FPGAs that require external configuration devices. The A42MX09 represents the entry-level density within the 14,000-gate segment of this portfolio.

Replacement Considerations

Direct substitutes include other variants within the A42MX09 family with different package types, such as A42MX09-1TQ176I for a 176-pin TQFP. Cross-family upgrades may involve the A42MX16 or A42MX24 for increased logic capacity. Verify pin compatibility when selecting alternative packages within the same logical family.
