A42MX16-PQG208

Overview

The A42MX16-PQG208 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, housed in a 208-pin PQFP package. It features approximately 54,000 system gates and supports up to 202 user-programmable I/O pins. The device integrates configurable dual-port SRAM with access times as fast as 5 ns. It operates at supply voltages of 3.3V or 5.0V for both core and I/Os, ensuring PCI compliance. Performance metrics include a clock-to-out delay of 5.6 ns and support for 100 MHz FIFOs.

Feature Summary

• Single-chip ASIC alternative capable of consolidating logic from multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation with 3.3V or 5.0V core and I/O configurations.
• Enables deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Includes unique in-system diagnostic and verification capabilities via Silicon Explorer II.

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential counterfeit risks. Confirm RoHS compliance status and check for Product Change Notifications (PCNs) regarding assembly site updates or software modifications. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this model for designs requiring high gate density in a QFP footprint. Compare against A42MX36 variants if higher capacity is needed. Verify voltage compatibility with target I/O standards. Consider thermal dissipation requirements for the plastic package in enclosed environments.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are designed as cost-effective solutions for 5V applications, offering high performance while shortening development cycles. The family ranges from 3,000 to 54,000 system gates, providing scalable options for complex logic implementations.

Replacement Considerations

Direct substitutes within the same package may include other A42MX16 variants with different speed grades or temperature ratings. Cross-reference with A42MX36 models if increased logic resources are acceptable. Verify pinout compatibility before replacing existing designs.
