A42MX36-PQ240

Overview

The A42MX36-PQ240 is a Field Programmable Gate Array from the Microsemi 42MX family, housed in a PQFP-240 package. It provides 2438 Configurable Logic Blocks (CLBs) and approximately 36,000 system gates. The device supports mixed-voltage operation at 5.0V or 3.3V for both core and I/Os, featuring PCI-compliant inputs and outputs. Key architectural resources include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and up to 202 user-programmable I/O pins.

Feature Summary

• Supports mixed-voltage operation with 5.0V or 3.3V core and I/O supplies
• Includes configurable dual-port SRAM blocks for memory applications
• Features deterministic timing with user-controllable delay characteristics
• Provides high pin count with up to 202 programmable I/O connections

Applications

• Single-chip ASIC replacement designs
• PCI bus interface implementations
• High-speed data processing logic
• Complex state machine control systems

Procurement Notes

Verify the specific speed grade suffix associated with the -PQ240 package variant to ensure timing compliance. Confirm RoHS status and moisture sensitivity level requirements against project specifications. Check for active manufacturing status as legacy FPGA families may face end-of-life transitions.

Selection Notes

Select this model when 36,000 system gates and 2438 CLBs are required within a 240-pin plastic quad flatpack form factor. Ensure the design utilizes the available dual-port SRAM capacity if memory functions are needed. Verify that the target voltage domain matches the 5.0V or 3.3V mixed-mode capabilities defined in the datasheet.

Part Context

This component belongs to the Microsemi 42MX FPGA family, designed as a high-capacity single-chip alternative to ASICs. The family offers scalable gate counts ranging from 3,000 to 54,000 system gates across various packages. The 42MX series is distinguished by its support for mixed-voltage I/O and integrated SRAM resources.

Replacement Considerations

Compatible replacements within the same family include the A42MX36-RQ240 and A42MX36-1RQG240, which offer similar gate counts but differ in package type or speed grade. Verify pinout compatibility and thermal characteristics before substitution.
