A42MX36-2BG272

Overview

The A42MX36-2BG272 is a high-capacity Field Programmable Gate Array (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 ranging from 3V to 3.6V or 4.75V to 5.25V. It includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions. The component utilizes a 272-pin Plastic Ball Grid Array (PBGA) package and offers deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.

Feature Summary

• Supports mixed-voltage operation allowing compatibility with both 3.3V and 5.0V core and I/O standards.
• Provides PCI-compliant I/O interfaces for direct integration with peripheral components.
• Enables 100% resource utilization and 100% pin locking for precise hardware design control.
• Features fast wide-decode circuitry to optimize logic execution speed.

Applications

• High-density digital signal processing implementations
• Complex state machine control systems
• Interface bridging between disparate voltage domains

Procurement Notes

Verify the specific suffix code against official Microchip documentation to confirm temperature range and package variant. Confirm current availability status as legacy products may have limited supply chains. Ensure compliance with RoHS and REACH regulations required for your manufacturing environment. Check for any Product Change Notices (PCN) regarding assembly sites or software tool updates that may affect long-term support.

Selection Notes

Select this model when 54,000 system gates are required in a BGA form factor. Compare against the A42MX36-2PQG208 if a QFP package is preferred over PBGA. Consider the -3 speed grade variant if lower propagation delays are necessary for high-frequency designs. Verify that the 272-pin footprint matches the target PCB layout constraints.

Part Context

This component belongs to the Microchip A42MX series, which bridges the gap between CPLDs and larger FPGAs. The MX family is characterized by its non-volatile Flash technology, eliminating the need for external configuration memory. This specific part represents the highest gate count within the standard A42MX36 architecture, offering significant logic density for compact applications.
