• Mixed-voltage capability allowing flexible integration of 3.3V and 5.0V domains within one system
• Integrated dual-port SRAM providing fast access times for data buffering and FIFO applications
• Supports 100% pin locking and resource utilization for precise hardware design control

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces requiring mixed voltage levels
• DSP and co-processor function acceleration
• Industrial and military temperature environment logic consolidation

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm exact electrical characteristics and package dimensions. Check for Product Change Notifications (PCN) regarding assembly sites or material composition updates. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process before procurement.

Selection Notes

Select this model when designing systems requiring 54,000 equivalent system gates with a 208-pin footprint. Ensure the design utilizes the available 2.5 kbits of SRAM efficiently. Verify that the target application operates within the specified voltage ranges for both core and I/Os. Consider the package thermal performance if operating at maximum clock frequencies.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are engineered to provide cost-effective solutions for complex logic designs. The family is known for bridging the gap between simple programmable logic and complex FPGAs, offering high performance with lower power consumption compared to older technologies.

Replacement Considerations

Direct replacements may include other variants within the A42MX36 series with different package options, such as CQFP or TQFP, if pin compatibility allows. Cross-referencing with the A42MX16 or A42MX24 models is not recommended due to significant differences in gate count and I/O availability.
