A42MX16-2PQG208I

Overview

The A42MX16-2PQG208I is a field-programmable gate array (FPGA) from the Microchip MX series, housed in a 208-pin PQFP package. It provides 24,000 system gates and supports up to 176 user-programmable I/O pins. The device integrates 2560 bits of configurable dual-port SRAM for embedded memory functions. It operates within a supply voltage range of 3V to 3.6V or 4.75V to 5.25V and is rated for commercial temperatures between 0°C and 70°C.

Feature Summary

• Single-chip ASIC alternative consolidating logic from multiple PALs, CPLDs, and FPGAs
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O configurations
• Deterministic timing with user-controllable delays and pin locking capabilities

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Review latest Product Change Notices for manufacturing site updates. Ensure storage conditions meet JESD-020 standards to prevent damage before reflow soldering.

Selection Notes

Select this model for designs requiring mixed-voltage compatibility and deterministic timing control. Verify that the 208-PQFP footprint matches the target PCB layout. Consider the 24K gate capacity against specific logic requirements. Check if the 2560-bit SRAM meets data buffering needs without external memory.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, designed as cost-effective solutions for 5V systems. These devices serve as high-performance replacements for complex discrete logic, offering significant resource utilization and integration benefits for legacy and new industrial designs.

Replacement Considerations

Public documentation indicates the A42MX16/A42MX24/A42MX36 family is obsolete. No direct public substitute part numbers are confirmed. Evaluate migration to newer Microchip FPGA families such as ProASIC3 or IGLOO2 for long-term availability.
