A42MX36-3PQG208

Overview

The A42MX36-3PQG208 is a non-volatile Flash FPGA from the Microchip MX series, manufactured by Microchip Technology. It features 54,000 system gates and 176 I/Os within a 208-pin PQFP package. The device operates on 3.3V or 5V supplies with voltage ranges of 3V–3.6V and 4.75V–5.25V respectively. It supports industrial temperature ranges from -55°C to +125°C. Key specifications include 2438 CLBs, 2560 bits of RAM, and a maximum clock frequency of 99 MHz.

Feature Summary

• Non-volatile Flash-based architecture eliminates the need for external configuration memory.
• Supports both 3.3V and 5V power supply voltages for flexible integration.
• Industrial-grade operating temperature range ensures reliability in harsh environments.

Applications

• Industrial control systems requiring high reliability.
• Automotive electronics operating under extreme temperatures.
• Military and aerospace applications demanding radiation tolerance.

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to widespread counterfeiting risks. Confirm RoHS compliance status as some legacy variants may differ. Check for End-of-Life (EOL) notices and Last-Time-Buy dates, as this part number has been subject to discontinuation announcements. Ensure moisture sensitivity level handling protocols are followed during assembly.

Selection Notes

Select the A42MX36-3PQG208 when high gate density and non-volatility are required without external configuration chips. Compare against the A42MX36-2PQG208 for speed grade differences; the '-3' suffix indicates a faster speed bin. Consider package availability, as the 208-PQFP form factor may have limited current production compared to BGA options.

Part Context

This component belongs to the Microsemi/Actel A42MX family, known for radiation-hardened, non-volatile FPGAs. It serves as a bridge between complex ASICs and standard volatile FPGAs, offering instant-on capability. The MX series is widely used in secure and safety-critical applications where data retention without power is essential.

Replacement Considerations

Direct pin-compatible replacements include the A42MX36-2PQG208 (slower speed grade) and A42MX36-1PQG208B. For higher performance, consider the A42MX38 series if gate count allows. Verify that any substitute maintains the same 208-PQFP package and voltage requirements.
