A42MX16-1PQG160M

Overview

The A42MX16-1PQG160M is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 14000 system gates and 336 Logic Elements (LEs). The device supports mixed-voltage operation with core voltages of 3V to 3.6V and I/O voltages of 4.75V to 5.25V. It offers 101 user-programmable I/O pins in a 160-BQFP package. Operating temperatures range from 0°C to 70°C for commercial variants. The architecture includes up to 2.5 kbits of configurable dual-port SRAM and fast wide-decode circuitry.

Feature Summary

• Single-chip solution integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Mixed-voltage capability allowing independent 3.3V core and 5.0V I/O operation
• Supports deterministic timing with user-controllable constraints and pin locking
• Includes diagnostic capabilities via Silicon Explorer II for in-system verification

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Check for RoHS compliance status and REACH registration details on official datasheets. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Validate that the specific suffix matches the required temperature grade and package variant before procurement.

Selection Notes

Select this model when replacing legacy complex programmable logic devices with higher density requirements. Ensure design compatibility with 5V tolerant I/O if interfacing with older systems. Consider the 160-pin QFP package constraints for PCB layout. Verify that the available 2.5 kbits of embedded memory meets the specific buffering needs of the application design.

Part Context

This component belongs to the 40MX and 42MX FPGA families, which are established as cost-effective solutions for mid-density logic applications. These devices bridge the gap between simple PLDs and high-end FPGAs, offering rapid development cycles. The MX series is widely recognized for its reliability in industrial and automotive environments due to robust radiation tolerance and wide operating temperature ranges.

Replacement Considerations

Direct replacements may include other parts within the A42MX family with adjusted gate counts, such as the A42MX09 or A42MX24, depending on resource utilization. Cross-family migration to newer Microchip PolarFire or IGLOO2 series may be necessary for long-term supply assurance, though pinouts and architectures will differ significantly.
