A42MX24-2PL84I

Overview

The A42MX24-2PL84I is a Field Programmable Gate Array (FPGA) from the Microchip A42MX family, designed as a single-chip ASIC alternative for automotive applications. It features 36,000 system gates and 912 logic elements within a PLCC-84 package. The device supports mixed-voltage operation at 5V or 3.3V with PCI-compliant I/Os. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and deterministic user-controllable timing. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides a single-chip ASIC alternative with high capacity ranging from 3,000 to 54,000 system gates.
• Supports mixed-voltage operation for core and I/Os at 5.0V or 3.3V levels.
• Enables up to 100% resource utilization and 100% pin fixing for design flexibility.
• Offers unique in-system diagnostic capability using Silicon Explorer II technology.

Applications

• Automotive applications requiring single-chip ASIC alternatives
• Industrial control systems needing deterministic timing
• Mixed-voltage interface designs with PCI-compliant requirements

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm package type is PLCC-84. Check current availability status as older FPGA models may have discontinuation notices. Ensure RoHS compliance status matches project requirements, noting some variants are non-compliant.

Selection Notes

Select this model when 36,000 system gates and 72 I/O pins are required in a PLCC-84 package. Compare against other A42MX variants based on gate count and package size. Consider the 5V/3.3V mixed-voltage capability if interfacing with legacy components. Verify timing requirements against the device's maximum clock frequency specifications.

Part Context

This component belongs to the Actel/Microchip A42MX family of flash-based FPGAs. These devices are known for instant-on functionality and radiation tolerance options. The A42MX series targets cost-sensitive applications replacing complex discrete logic or ASICs, particularly in automotive and industrial sectors where reliability and low power consumption are critical.

Replacement Considerations

Direct replacements include other A42MX24 variants with different packages like PL84A or PQ208A. Cross-reference with A40MX series for lower gate counts. Verify pin compatibility and voltage levels before substituting with newer Microchip FPGA families.
