A42MX24-1PL84I

Overview

The A42MX24-1PL84I is a Field Programmable Gate Array (FPGA) from the Microchip A42MX family, designed as a single-chip ASIC alternative for automotive and industrial applications. It features 36,000 system gates and 912 logic elements within a Plastic Leaded Chip Carrier (PLCC-84) package. The device operates at a maximum clock frequency of 96 MHz with a configurable dual-port SRAM capacity up to 2.5 kbits. It supports mixed-voltage operation at 3.3V or 5.0V and includes IEEE Standard 1149.1 JTAG boundary scan testing. The component is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides deterministic, user-controllable timing suitable for ASIC design methodologies
• Supports up to 100% resource utilization and 100% pin fixing for integration ease
• Enables unique in-system diagnostic capability via Silicon Explorer II
• Features fast wide-decode circuitry and mixed-voltage I/O compatibility

Applications

• Automotive electronic control units requiring high reliability
• Industrial automation systems needing deterministic timing
• Single-chip ASIC replacement designs
• Mixed-voltage interface circuits with PCI-compliant I/Os

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as documentation indicates non-compliance for some variants. Check for End-of-Life notifications or discontinuance notices from Microchip Technology prior to procurement. Ensure the PLCC-84 package availability aligns with current manufacturing schedules.

Selection Notes

Select this model when 36,000 system gates and 72 user-programmable I/O pins are required in a PLCC-84 footprint. Choose the '-1' speed grade if a maximum operating frequency of 96 MHz meets the design constraints. Verify that the 3.3V or 5.0V mixed-voltage operation matches the target system power supply requirements.

Part Context

This component belongs to the A42MX FPGA family, which bridges the gap between standard FPGAs and custom ASICs. The series emphasizes low power consumption and high density, offering up to 54,000 system gates across various packages. It is engineered for environments demanding robust performance and long-term availability.

Replacement Considerations

Direct substitutes include other A42MX family members such as A42MX24-PL84A or A42MX24-PL84I with different speed grades. Cross-reference pinouts and electrical characteristics carefully when considering legacy Actel-branded equivalents.
