A42MX09-FPLG84

Overview

The A42MX09-FPLG84 is a Field Programmable Gate Array from the Microchip MX Automotive family, housed in an 84-pin FineLine PLCC package. It provides 14,000 system gates and supports up to 72 user-programmable I/O pins. The device operates on a single 5V supply voltage with a minimum of 4.75V and a maximum of 5.25V. It features a commercial temperature range of 0°C to +70°C. Key internal resources include configurable dual-port SRAM and fast wide-decode circuitry designed for deterministic timing.

Feature Summary

• Single-chip ASIC alternative offering high performance and consolidated logic implementation
• Supports mixed-voltage operation with PCI-compliant I/Os
• Enables up to 100% resource utilization and pin locking
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

• Automotive applications requiring single-chip solutions
• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix 'F' against official Microchip documentation to confirm it denotes the commercial temperature grade (0°C to +70°C) rather than an industrial or automotive variant. Ensure the package type matches the 84-pin FineLine PLCC specification. Cross-reference the part number with current datasheets to confirm availability status and any recent design changes.

Selection Notes

Select this component when a cost-effective 5V FPGA solution is required for consolidating PALS, CPLDs, or other FPGAs into a single chip. It is suitable for designs needing deterministic timing and up to 14,000 system gates. Consider the 84-pin PLCC package constraints and verify that the 72 available I/O pins meet the interface requirements.

Part Context

This part belongs to the Microchip MX Automotive family of FPGAs, which are designed as single-chip ASIC alternatives. The series ranges from 3,000 to 54,000 system gates and includes configurable dual-port SRAM. These devices support synthesis-friendly architectures and are intended to shorten system design and development cycles.

Replacement Considerations

Check for direct substitutes within the A42MX09 series with different package options, such as PQFP or TQFP variants, if pin compatibility allows. Verify if older A40MX09 models are compatible, noting potential differences in gate count or speed grades.
