A42MX09-FPQG100

Overview

The A42MX09-FPQG100 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Actel. It features 336 Configurable Logic Blocks (CLBs), 684 logic cells, and an equivalent of 14,000 system gates. The device supports a maximum clock frequency of 70.2 MHz with a CLB maximum combinational delay of 3.5 ns. It operates within a supply voltage range of 4.5 V to 5.5 V, though it can also operate at 3.3 V for I/O supplies. The component utilizes a PQFP-100 plastic package with 100 terminals and has a moisture sensitivity level of 3.

Feature Summary

• Single-chip ASIC alternative offering high capacity with up to 54,000 system gates across the family.
• Includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.
• Supports mixed-voltage operation with PCI-compliant I/Os for versatile integration.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.

Applications

• High-reliability aerospace and defense systems requiring HiRel features.
• Industrial automation controllers needing single-chip ASIC replacement.
• Military communication equipment utilizing commercial or military temperature packages.
• Automotive electronic control units (ECUs) requiring robust programmable logic.

Procurement Notes

Verify the manufacturer origin, as this part was originally produced by Actel before acquisition by Microsemi and subsequently Microchip. Confirm RoHS compliance status, as older Actel-branded variants may differ from current Microchip specifications. Ensure the specific suffix matches the required temperature grade and package type. Request official datasheets to validate electrical parameters against design requirements. Check for any relevant Product Change Notices (PCNs) regarding assembly sites or material updates.

Selection Notes

Select this model for designs requiring approximately 14,000 system gates in a 100-pin QFP package. Compare performance metrics such as the 70.2 MHz speed grade against higher-speed variants like the A42MX09-3 if faster timing is needed. Consider the available SRAM resources for data buffering needs. Evaluate thermal dissipation capabilities within the PQFP-100 enclosure for the target application environment.

Part Context

This component belongs to the A42MX09 series within the broader MX FPGA family. It shares architectural similarities with other devices in the series, such as the A42MX16 and A42MX24, which offer higher gate counts but similar interface characteristics. The series is known for its flash-based non-volatile technology, allowing instant-on functionality without external configuration memory.

Replacement Considerations

Direct substitutes include other members of the A42MX09 series with different speed grades or package options, such as A42MX09-2PG100A or A42MX09-FVQG100. Cross-family replacements from Microchip's PolarFire or IGloo2 lines may be considered for updated feature sets, though pinouts and logic capacities will differ significantly.
