A42MX16-PQ208I

Overview

The A42MX16-PQ208I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, housed in a 208-pin PQFP package. It features 24,000 system gates and 608 logic elements with 83 I/O pins. The device operates on dual voltage supplies: 4.5 V to 5.5 V or 3.3 V to 3.6 V for the core, supporting mixed-voltage I/O configurations. It functions within an industrial temperature range of -40°C to +85°C. This non-volatile FPGA serves as a single-chip ASIC alternative, integrating high-performance logic without requiring external configuration memory.

Feature Summary

• Non-volatile flash-based architecture eliminates the need for external configuration PROMs.
• Supports mixed-voltage operation allowing 5.0V or 3.3V core and I/O combinations.
• Provides deterministic timing with user-controllable delays and pin locking capabilities.
• Includes built-in diagnostic features compatible with Silicon Explorer II for in-system verification.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• DSP and co-processor function consolidation

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to discontinuation status. Confirm RoHS compliance and MSL rating prior to assembly. Review latest PCN documents for manufacturing site changes. Ensure ESD handling protocols are followed during storage and installation.

Selection Notes

Select this model for designs requiring 24K system gates in a 208-pin form factor. Compare against A42MX36 for higher capacity needs or A42MX16 variants with different temperature grades. Verify voltage compatibility between the 3.3V and 5V operating modes and target system interfaces.

Part Context

This component belongs to the Microchip MX family, which bridges the gap between CPLDs and FPGAs. It utilizes Actel's patented non-volatile flash technology. The part replaces legacy PALs and CPLDs in complex digital logic applications while offering reprogrammability.

Replacement Considerations

Check for A42MX16-PQ208A if commercial temperature grade suffices. Consider A42MX36-PQ208I for increased logic density within the same package footprint. Verify functional equivalence before substituting with other MX series devices.
