A42MX16-1TQG176M

Overview

The A42MX16-1TQG176M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip 42MX family. It features 608 Configurable Logic Blocks (CLBs) and approximately 24,000 system gates. The device supports a maximum clock frequency of 117 MHz and includes up to 2.5 kbits of configurable dual-port SRAM. It operates with mixed-voltage I/Os supporting both 5.0V and 3.3V levels. The component is housed in a 176-pin Thin Quad Flatpack (TQFP) package.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• Mixed-voltage operation capability for core and I/Os with PCI-compliant interfaces
• In-system diagnostic and verification capability via Silicon Explorer II

Applications

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

Procurement Notes

Verify the manufacturer source carefully, as Actel was acquired by Microsemi, which is now part of Microchip Technology. Confirm the specific suffix 'M' indicates the correct temperature grade and package variant against the official datasheet. Ensure the design-in process accounts for the legacy nature of the 42MX family and availability constraints.

Selection Notes

Select this model when 608 CLBs and 117 MHz performance are required in a 176-pin TQFP form factor. Compare against the A42MX16-2TQG176M if higher speed grades are needed. Consider the A42MX36 series if greater gate density is necessary for complex logic implementations.

Part Context

This component belongs to the Microchip 42MX FPGA family, designed as a cost-effective solution for consolidating logic designs. The family offers high capacity ranging from 3,000 to 54,000 system gates, targeting applications that require high performance and short development cycles compared to traditional discrete logic solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip's official obsolescence notices or contact technical support for current lifecycle status and potential migration paths.
