A42MX09-TQG176

Overview

The A42MX09-TQG176 is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series. It features 336 Logic Elements and approximately 14,000 system gates. The device supports dual voltage operation with a minimum supply of 3.0V and maximum of 3.6V for 3.3V logic, or 4.75V to 5.25V for 5V logic. It provides 104 I/O pins in a 176-pin Thin Quad Flat Package (TQFP). Operating temperatures range from 0°C to +70°C.

Feature Summary

• Flash-based non-volatile architecture eliminates the need for external configuration memory.
• Supports in-system programming and partial reconfiguration capabilities.
• Dual voltage operation allows compatibility with both 3.3V and 5V logic standards.

Applications

• Industrial control systems requiring reliable programmable logic.
• Automotive electronics applications within specified temperature ranges.
• Communication interface adapters and protocol converters.

Procurement Notes

Verify the specific suffix TQG176 against official Microchip documentation to confirm package dimensions and pinout. Ensure compliance with RoHS directives as indicated in current manufacturing notices. Check for any Product Change Notifications regarding software tools or assembly updates before finalizing procurement plans.

Selection Notes

Select this component when a moderate gate count with 104 I/Os is required in a TQFP-176 package. Consider the MX series advantages for designs needing instant-on functionality without external boot devices. Compare against A42MX09 variants with different speed grades or packages if timing constraints or board space differ.

Part Context

This part belongs to the A42MX09 family, which offers scalable logic resources within the broader MX FPGA portfolio. It shares architectural similarities with other Flash FPGAs but is distinct in its specific I/O count and package configuration compared to higher-density models like the A42MX16 or A42MX24.

Replacement Considerations

Direct substitutes include other A42MX09 variants with compatible packages such as A42MX09-FTQG176. Verify pin-to-pin compatibility and electrical specifications before substitution. Cross-reference with Microchip's official obsolescence notices to ensure long-term availability.
