A42MX16-1PQ160

Overview

The A42MX16-1PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX series. It features 24,000 system gates and 608 Logic Elements. The device supports up to 125 user-programmable I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 160-pin PQFP package with dimensions of 28x28 mm. The component supports surface mount installation and functions at temperatures between -40°C and +125°C.

Feature Summary

• High-capacity single-chip ASIC alternative providing up to 24,000 system gates
• Mixed-voltage operation capability for core and I/Os with PCI-compliant interfaces
• 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 against official datasheets to confirm temperature grade and package variant. Check for Product Change Notifications regarding assembly sites or software updates. Confirm end-of-life status as discontinuation notices may affect long-term availability. Ensure compliance with RoHS3 and REACH regulations for your region.

Selection Notes

Select this model when 24,000 system gates and mixed-voltage I/O support are required. Compare gate counts and I/O limits against similar MX family members like the A42MX09 or A42MX24. Verify that the 160-pin PQFP package fits the board layout constraints. Ensure the 4.5V to 5.5V supply requirement matches the system power design.

Part Context

This part belongs to the Microsemi/Actel 40MX and 42MX FPGA families, designed as cost-effective single-chip solutions. These devices consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. The family offers high performance with fast wide-decode circuitry and configurable dual-port SRAM capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider reviewing other models within the A42MX16 series or the broader 40MX/42MX family for pin-compatible or functionally equivalent alternatives.
