A42MX09-1PLG84I

Overview

The A42MX09-1PLG84I is a field-programmable gate array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative for automotive applications. It features 14,000 system gates and 336 logic elements within a PLCC-84 package. The device supports mixed-voltage operation with core voltages of 3V to 3.6V and I/O voltages of 4.75V to 5.25V. It operates within an industrial temperature range of -40°C to +85°C and includes up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Supports mixed-voltage operation allowing independent core and I/O supply configurations
• Provides deterministic, user-controllable timing suitable for precise design methodologies
• Enables up to 100% resource utilization and pin locking for direct ASIC replacement

Applications

• Single-chip ASIC replacement in automotive electronic control units
• Industrial control systems requiring deterministic timing
• Mixed-signal interface bridging between 3.3V and 5V domains

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified secondary market suppliers. Confirm RoHS compliance status and manufacturing date codes against current discontinuation notices. Ensure storage conditions adhere to moisture sensitivity level 3 requirements prior to reflow soldering processes.

Selection Notes

Select this model when 14,000 system gates and a PLCC-84 footprint are required for mixed-voltage designs. Compare against the A42MX09-1PQG100I if a QFP-100 package is preferred. Verify that the 4.75V to 5.25V I/O voltage range aligns with the target system's power supply specifications.

Part Context

This component belongs to the Microchip A42MX09 series, part of the broader MX FPGA family. The series offers scalable gate counts ranging from 3,000 to 54,000 system gates. The A42MX09 specifically targets applications needing moderate logic density with high reliability and low power consumption characteristics.

Replacement Considerations

Direct pin-compatible replacements may include other variants within the A42MX09 series such as the A42MX09-1PQG100I or A42MX09-PQG144, provided the package type matches the PCB layout. Verify electrical parameters and timing constraints before substitution.
