A42MX16-PQG100I

Overview

The A42MX16-PQG100I is a field-programmable gate array from the Microchip MX family, housed in a PQFP-100 surface-mount package. It provides 608 logic elements and 24,000 system gates with 83 user-programmable I/O pins. The device operates on a supply voltage ranging from 4.5 V to 5.5 V, supporting both 3.3 V and 5 V core and I/O configurations. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative integrating high-capacity programmable logic
• Supports mixed-voltage operation for 3.3V or 5.0V core and I/Os
• Includes configurable dual-port SRAM for data storage applications

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix 'PQG100I' against the manufacturer's current datasheet DS2316 to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the PQFP-100 form factor. Check for moisture sensitivity level requirements during assembly handling.

Selection Notes

Select this component when a cost-effective single-chip solution replaces multiple PALs, CPLDs, or FPGAs. Consider the 24K system gate capacity and 83 I/O count for moderate complexity designs requiring deterministic timing and mixed-voltage support.

Part Context

This part belongs to the A42MX16 series within the broader 40MX and 42MX FPGA families. These devices are designed to consolidate logic functions while shortening development cycles. The PQG100I variant specifically denotes the plastic quad flat pack package with industrial temperature rating.

Replacement Considerations

Compatible substitutes include other variants within the A42MX16 family such as A42MX16-VQG100A or A42MX16-PL100A, provided pinout and thermal specifications match the design requirements.
