A42MX16-TQ176I

Overview

The A42MX16-TQ176I is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, designed as a high-capacity single-chip ASIC alternative. It features 24,000 system gates and supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V. The device includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic, user-controllable timing. It operates within a temperature range of -40°C to +85°C and utilizes a 176-pin Thin Quad Flatpack (TQFP) surface-mount package.

Feature Summary

• Supports mixed-voltage operation for both core logic and I/O pins at 3.3V or 5.0V levels
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities
• Integrates configurable dual-port SRAM for fast data access and FIFO applications

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Military and aerospace applications requiring commercial, industrial, automotive, or military temperature plastic packages

Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm specific ordering suffixes against official datasheets to ensure correct speed grades and package types. Check for Product Change Notifications (PCN) regarding manufacturing updates. Validate RoHS compliance status prior to integration into regulated assemblies.

Selection Notes

Select this model when a cost-effective FPGA solution consolidating multiple PALs, CPLDs, or FPGAs is required. Ensure the design fits within the 24,000 gate capacity and 2.5 kbit SRAM limits. Verify that the 176-pin TQFP package meets board space constraints. Consider the -40°C to +85°C operating range for environmental suitability.
