A42MX16-CQ172B

Overview

The A42MX16-CQ172B is a Field Programmable Gate Array (FPGA) belonging to the MX Automotive Family, manufactured by Microchip Technology. It features 24,000 system gates and is housed in a 172-pin Plastic Quad Flatpack (PQFP) package. The device operates within a voltage range of 4.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Key architectural components include configurable dual-port SRAM, fast wide-decode circuitry, and support for up to 100% resource utilization with deterministic timing.

Feature Summary

• Single-chip ASIC alternative designed for automotive applications
• Supports mixed-voltage operation with PCI-compliant I/Os
• Features unique in-system diagnostic capability with Silicon Explorer II

Applications

• Automotive electronic control units
• High-speed controllers and address decoding
• Peripheral bus interfaces and DSP functions

Procurement Notes

Verify RoHS compliance status as specific documentation for this suffix may vary. Confirm the manufacturer source, noting that Microsemi was acquired by Microchip Technology. Ensure the datasheet matches the exact part number to validate package type and temperature grade before procurement.

Selection Notes

Select this model for designs requiring high gate density in a PQFP package. Verify that the 4.5V to 5.5V supply requirement aligns with the system power architecture. Consider the -40°C to +85°C operating range against environmental constraints.

Part Context

This component is part of the A42MX series, which provides cost-effective FPGA solutions for consolidating logic previously implemented in PALs, CPLDs, or other FPGAs. The series is characterized by its synthesis-friendly architecture and support for standard ASIC design methodologies.

Replacement Considerations

Compatible substitutes within the same family include A42MX16 variants with different packages such as A42MX16-PQG100A or A42MX16-2TQG176I. Cross-family replacements from the A40MX series offer lower gate counts.
