A42MX09-3TQ176

Overview

The A42MX09-3TQ176 is a Field Programmable Gate Array (FPGA) belonging to the Microsemi 40MX and 42MX families. It features 14,000 system gates organized into 684 Configurable Logic Blocks (CLBs). The device provides 150 user-programmable I/O pins and operates within a supply voltage range of 4.75 V to 5.25 V. It supports mixed-voltage operation for core and I/Os, including PCI-compliant levels. The component utilizes a 176-pin Thin Quad Flat Package (TQFP) with a commercial temperature rating of 0°C to +70°C.

Feature Summary

• High-capacity single-chip ASIC alternative offering up to 54,000 system gates across the family
• Integrated configurable dual-port SRAM supporting up to 2.5 kbits capacity
• Mixed-voltage operation capability allowing 5.0V or 3.3V core and I/O configurations
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm the commercial temperature grade (0°C to +70°C) and speed bin. Confirm package integrity for the 176-TQFP form factor. Check current lifecycle status as MX series components may face discontinuation. Ensure ESD handling protocols are followed due to moisture sensitivity level 3 classification.

Selection Notes

Select this model when 14,000 system gates and 150 I/Os are required in a TQFP-176 package. Compare against A42MX09 variants with different suffixes for industrial or military temperature ranges if operating conditions exceed commercial limits. Verify that the 5V supply requirement aligns with the system design, as the core logic typically requires 5V operation.

Part Context

This component is part of the Actel MX FPGA family, originally developed by Microsemi Corporation and now managed by Microchip Technology. The 40MX/42MX series is designed as a cost-effective solution for replacing complex PALs, CPLDs, and FPGAs. These devices are known for their non-volatile flash technology, which eliminates the need for external configuration memory.

Replacement Considerations

Publicly confirmed substitute part numbers for the exact A42MX09-3TQ176 specification are not available in the provided documentation. Consider reviewing other A42MX09 variants with different temperature grades or speed bins, such as those ending in 'I' for industrial ratings, if functional equivalence allows.
