A42MX36-2PQG208

Overview

The A42MX36-2PQG208 is a Microchip Technology MX series Field Programmable Gate Array (FPGA) housed in a 208-BFQFP package. It features approximately 54,000 system gates and 176 I/O pins. The device includes 2,560 bits of embedded RAM. It operates within a supply voltage range of 3V to 3.6V or 4.75V to 5.25V. The commercial temperature grade supports operation from 0°C to 70°C. This component is part of the Actel portfolio and is currently listed as obsolete.

Feature Summary

• Non-volatile flash-based FPGA architecture for instant-on functionality
• High-density logic implementation with significant gate count capacity
• Integrated embedded memory resources for data storage

Applications

• Industrial control systems requiring reliable programmable logic
• Telecommunications infrastructure equipment
• Automotive electronic modules

Procurement Notes

This component is officially discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets. Buyers must confirm the specific revision level and physical condition of existing stock. Compliance with RoHS3 standards is documented. End-of-life notifications indicate final shipments have ceased, necessitating careful evaluation of long-term support requirements for production integration.

Selection Notes

Engineers selecting this part should consider its non-volatile flash technology which eliminates configuration boot times compared to volatile SRAM FPGAs. The 208-pin QFP package offers a balance of I/O density and board space. Designers must account for the dual voltage supply options during power rail planning. Due to the obsolete status, alternative components with similar gate counts and pinouts should be evaluated for new designs to ensure supply chain stability.

Part Context

The A42MX36 belongs to the Microchip MX family, derived from the legacy Actel FPGA line. These devices are characterized by their radiation tolerance and low power consumption profiles. The -2 speed grade indicates specific timing performance characteristics relative to other variants in the A42MX36 series. The PQG208 suffix denotes the plastic quad flat pack package with gull-wing leads.

Replacement Considerations

Direct replacements are limited due to the obsolete status. Potential alternatives include other Microchip RTG4 or PolarFire series FPGAs, though pinouts and architectures differ significantly. Engineers should consult Microchip's official obsolescence notices for recommended migration paths or cross-reference with generic high-density CPLDs if logic density permits.
