A40MX02-PL68A

Overview

The A40MX02-PL68A is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a high-capacity single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 3,000 system gates. The device supports mixed-voltage operation with a core supply of 3.3V or 5.0V and PCI-compliant I/Os. It utilizes a 68-pin Plastic Leadless Chip Carrier (PLCC) package suitable for surface-mount installation. The component includes fast wide-decode circuitry and up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions.

Feature Summary

• Supports mixed-voltage operation allowing 5.0V or 3.3V core and I/O configurations with PCI-compliant interface standards.
• Provides deterministic timing through user-controllable logic resources and 100% pin locking capabilities.
• Integrates up to 2.5 kbits of configurable dual-port SRAM for embedded data storage applications.

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-voltage digital logic interfacing systems
• PCI-compliant peripheral controller implementations

Procurement Notes

Verify the specific suffix against official datasheets, as standard commercial variants typically utilize an 'I' designation for industrial temperature ranges. Confirm moisture sensitivity levels and lead-free compliance status prior to ordering to ensure compatibility with assembly processes.

Selection Notes

Select this component for applications requiring moderate logic density with flexible voltage domains. Ensure the design accommodates the PLCC-68 footprint dimensions. Verify that the required clock frequencies align with the device's specified propagation delays and maximum operating speeds.

Part Context

This part belongs to the Actel MX FPGA series, originally developed by Actel and acquired by Microsemi, now Microchip Technology. The MX family is characterized by non-volatile flash-based technology, eliminating the need for external configuration memory and enabling instant-on functionality in embedded systems.

Replacement Considerations

Direct replacements include the A40MX02-PLG68I and A40MX02-3PL68IX79. These variants share identical logical resources and pinouts but may differ in temperature ratings or specific speed grades. Verify package tolerance and electrical characteristics before substitution.
