A40MX04-2PL84I

Overview

The A40MX04-2PL84I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, featuring 6,000 system gates and 547 logic elements. It provides 69 user-programmable I/O pins within a PLCC-84 surface-mount package. The device operates on dual voltage supplies: 3.3V for the core and 5.0V for I/Os, with a supply range of 4.5V to 5.5V. It supports an industrial temperature range of -40°C to +85°C and includes IEEE 1149.1 JTAG boundary scan capabilities.

Feature Summary

• Single-chip ASIC alternative architecture supporting up to 100% resource utilization and pin locking.
• Integrated configurable dual-port SRAM for fast data processing applications.
• Deterministic timing characteristics with user-controllable delays.
• Supports in-system diagnostic capability via Silicon Explorer II.

Applications

• Automotive electronic control units requiring high reliability.
• Industrial automation controllers needing deterministic logic performance.
• Communication interface adapters utilizing mixed-voltage I/O standards.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the PLCC-84 package type matches the target footprint. Check for recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement orders.

Selection Notes

Select this model when 6,000 system gates and 69 I/Os are required for mixed-voltage 3.3V/5.0V designs. Ensure the design utilizes the MX family's synthesis-friendly architecture. Compare against the A40MX04-2PQG100I if a PQFP-100 package is preferred over PLCC-84 for the same logical capacity.

Part Context

This component belongs to the A40MX04 series within the broader MX FPGA portfolio. It shares the same 6,000-gate logical fabric as other variants like the A40MX04-2PLG44 but differs in package density and I/O count. The part represents a mid-range solution in the Actel/Microchip programmable logic lineup.

Replacement Considerations

Direct functional substitutes include other A40MX04 variants such as A40MX04-2PLG84I or A40MX04-2PQG100I, provided the package footprint difference is accommodated by the PCB design. No cross-family replacements are officially confirmed without redesign.
