A42MX16-3PQ208

Overview

The A42MX16-3PQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features approximately 24,000 system gates and 608 Logic Elements. The device supports mixed-voltage operation with a core voltage of 3.3V and I/O voltages compatible with 5.0V or 3.3V systems. It offers up to 140 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM. The component operates within a temperature range of -40°C to +85°C and is housed in a PQFP-208 surface-mount package.

Feature Summary

• Provides high-performance logic consolidation for applications previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports deterministic timing with 100% resource utilization and pin locking capabilities.
• Enables mixed-voltage operation allowing integration of 3.3V cores with 5.0V I/O interfaces.

Applications

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

Procurement Notes

Verify current availability status as the A42MX16 series has been subject to discontinuance notifications by the manufacturer. Confirm that the specific suffix matches required performance grades and packaging specifications before procurement planning.

Selection Notes

Select this model when design requirements involve moderate logic density around 24k gates with mixed-voltage I/O needs. Ensure the PQFP-208 footprint aligns with PCB layout constraints and verify thermal management capabilities for the specified industrial temperature range.

Part Context

This component belongs to the Microchip MX FPGA family, which bridges the gap between complex programmable logic devices and full-scale FPGAs. The series is characterized by its non-volatile flash technology and ability to operate at standard 5V or 3.3V levels without external level shifters.

Replacement Considerations

Check for updated PCNs regarding the A42MX16 series. Potential replacements may include other members of the A42MX family with higher gate counts or different package types, provided they meet the same voltage and I/O interface requirements.
