A42MX24-2PQG208I

Overview

The A42MX24-2PQG208I is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and 912 Logic Elements within a 208-pin PQFP package. The device supports mixed-voltage operation with core and I/O voltages of 5.0V or 3.3V. It includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable delays. The component operates within an industrial temperature range of 0°C to +70°C.

Feature Summary

• Provides a cost-effective single-chip solution for consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation allowing flexible integration of 5.0V or 3.3V core and I/O standards.
• Enables 100% resource utilization and 100% pin locking for precise hardware mapping.
• Includes unique in-system diagnostic capabilities via Silicon Explorer II technology.

Applications

• High-speed controllers and peripheral bus interfaces
• DSP and co-processor functions
• Address decoding and fast wide-decode circuitry

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (0°C to +70°C). Confirm the package type matches the 208-pin PQFP requirement. Check for RoHS compliance status as older revisions may vary. Ensure design files are compatible with current Microchip FPGA tools.

Selection Notes

Select this model when 36,000 system gates and 176 user-programmable I/O pins are required. Compare against lower-density variants like the A42MX16 if gate count exceeds needs. Consider the A42MX36 series if embedded memory resources are necessary for the application design.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families. These devices are engineered for applications requiring high performance and low power consumption. The family supports IEEE Standard 1149.1 JTAG boundary scan testing for verification.

Replacement Considerations

Direct substitutes include other members of the A42MX24 series with different packages, such as A42MX24-PQ208A or A42MX24-PL84A, provided pin compatibility and thermal requirements align with the design constraints.
