A42MX36-2BG272I

Overview

The A42MX36-2BG272I is a non-volatile Flash FPGA from the Microchip MX family, designed as a single-chip ASIC alternative. It features 54,000 system gates and 1,184 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with core and I/O supplies of 3.3V or 5.0V. It includes up to 2.5 kbits of configurable dual-port SRAM and offers up to 202 user-programmable I/O pins. The component utilizes a 272-pin Plastic Ball Grid Array (PBGA) package and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Non-volatile Flash architecture eliminates the need for external configuration memory.
• Supports mixed-voltage operation for both core logic and I/O interfaces.
• Provides deterministic timing with user-controllable delay characteristics.

Applications

• High-density digital logic replacement for custom ASIC designs.
• Industrial control systems requiring robust programmable logic.
• Automotive electronics applications compatible with standard voltage levels.

Procurement Notes

Verify the specific suffix 'I' confirms the commercial temperature grade (0°C to 70°C) against the official datasheet. Confirm the 272-ball PBGA package dimensions match the design footprint. Check current availability status as older MX series components may have limited stock or obsolescence notices.

Selection Notes

Select this model when 54,000 system gates and 202 I/Os are required in a BGA form factor. Ensure the design utilizes 3.3V or 5.0V supply rails compatible with the MX family specifications. Consider the non-volatile nature for simplified board layouts compared to volatile FPGAs.

Part Context

This part belongs to the A42MX series, which provides high-capacity programmable logic using Actel's proprietary Flash technology. The series is known for instant-on capabilities and radiation tolerance options, though this specific commercial variant focuses on cost-effective ASIC prototyping and low-volume production.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the end-of-life status of many MX parts. Verify if the A42MX36-3BG272IX79 serves as a functional substitute, noting potential differences in speed grades or industrial temperature ratings.
