A40MX04-PQ100M

Overview

The A40MX04-PQ100M is a field-programmable gate array from the Microchip MX family, housed in a PQFP-100 package. It provides 6,000 system gates and 547 logic elements with 202 user-programmable I/O pins. The device operates at supply voltages of 3.3 V or 5.0 V for core and I/Os. Maximum clock frequency reaches 250 MHz with a 5.6 ns clock-to-out delay. It includes up to 2.5 kbits of configurable dual-port SRAM and supports JTAG boundary scan testing.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Mixed-voltage operation capability supporting both 3.3V and 5.0V core and I/O configurations
• Deterministic timing with user-controllable resource utilization and pin locking

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and coprocessor functions

Procurement Notes

Verify the manufacturer origin carefully, as Actel was acquired by Microsemi, now part of Microchip Technology. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the specific suffix matches your voltage and temperature grade needs. Request official datasheets to validate pinout and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when designing cost-effective 5V or 3.3V systems requiring high-density programmable logic in a QFP package. Compare against other MX series variants if different I/O counts or package types are required. Consider the 2.5 kbits SRAM capacity for embedded memory needs. Verify that the 250 MHz performance meets your timing constraints for the intended application.

Part Context

This part belongs to the 40MX and 42MX FPGA families, originally developed by Actel Corporation before its acquisition by Microsemi and subsequently Microchip Technology. These devices are designed to replace complex discrete logic solutions, offering consolidation capabilities for industrial, automotive, and commercial applications.

Replacement Considerations

Check for direct substitutes within the same MX family with different package options like PLCC or TQFP. Verify compatibility with existing design tools such as Silicon Explorer II. Ensure any replacement maintains the same voltage levels and I/O count requirements.
