A42MX36-BGG272I

Overview

The A42MX36-BGG272I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It provides 54,000 system gates and 1,184 Logic Elements (LEs). The device supports up to 249 user-programmable I/O pins and features configurable dual-port SRAM for embedded memory needs. It operates within a supply voltage range of 4.75 V to 5.25 V and is rated for an industrial temperature range of -40°C to +85°C. The component is housed in a BGA-272 package suitable for surface mount technology.

Feature Summary

• High-density logic capacity with 54,000 system gates for complex digital designs
• Configurable dual-port SRAM support for flexible embedded memory applications
• Mixed-voltage operation capability supporting both 5.0V and 3.3V core and I/O standards
• Deterministic timing with user-controllable constraints for reliable system integration

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Industrial automation logic consolidation replacing multiple PLDs or CPLDs

Procurement Notes

Verify the specific suffix 'BGG272I' against official Microchip documentation to confirm the Ball Grid Array package type and industrial temperature rating. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm current availability status as MX series components may have limited production runs.

Selection Notes

Select this model when design requirements exceed the capacity of lower-gate MX devices but do not necessitate larger FPGA families. Consider the 5V operation requirement, as newer low-voltage FPGAs may require level shifting. Evaluate pin count sufficiency, as this part offers up to 249 I/Os, which is higher than the PQFP-208 variants.

Part Context

This component belongs to the Microchip Actel MX family, known for non-volatile Flash-based FPGA technology. The MX series allows for instant-on functionality and high reliability. The A42MX36 variant represents the upper end of gate density within this specific legacy family, bridging the gap between standard CPLDs and large-scale FPGAs.

Replacement Considerations

Direct pin-to-pin replacements are generally unavailable due to the proprietary nature of the MX architecture. Designers typically migrate to modern Microchip PolarFire or IGLOO2 families, requiring schematic and layout redesigns to accommodate different voltage levels and pin configurations.
