A42MX09-3PL84I

Overview

The A42MX09-3PL84I is a Field Programmable Gate Array (FPGA) from the Microchip MX Automotive family. It features 14,000 system gates and 336 Logic Elements (LEs). The device provides 72 I/O pins and operates within a supply voltage range of 4.5 V to 5.5 V. It supports an industrial temperature range from -40°C to +85°C. The component is housed in a PLCC-84 package.

Feature Summary

• Single-chip ASIC alternative for automotive applications
• Deterministic, user-controllable timing with up to 100% resource utilization
• Unique in-system diagnostic capability with Silicon Explorer II
• Supports IEEE Standard 1149.1 (JTAG) boundary scan testing

Applications

• Automotive electronic control units
• Industrial motor control systems
• High-reliability logic replacement

Procurement Notes

Verify the specific suffix 'I' against official datasheets to confirm the industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as some variants may differ. Check for end-of-life notifications or discontinuance alerts prior to ordering.

Selection Notes

Select this model for designs requiring deterministic timing and high pin-fixing ratios. Ensure the 4.5V to 5.5V supply voltage aligns with the system power architecture. Verify that the PLCC-84 package footprint matches the PCB layout requirements.

Part Context

This part belongs to the A42MX series, designed as a radiation-tolerant, single-chip ASIC alternative. The series offers scalable gate counts from 3,000 to 54,000 system gates, targeting automotive and industrial markets requiring high reliability and low power consumption.

Replacement Considerations

Direct substitutes include other A42MX series devices such as A42MX09-3PLG84I or A42MX16 variants if higher capacity is needed. Cross-reference with A40MX series for legacy compatibility.
