A42MX36-1PQ208M

Overview

The A42MX36-1PQ208M is a Field Programmable Gate Array (FPGA) from the MX family, manufactured by Microchip Technology. It features 54,000 system gates and 1,184 Logic Elements (LEs). The device provides 176 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM. It operates at supply voltages of 3.3V or 5.0V and supports a maximum clock frequency of 71 MHz with a typical CLB combinatorial delay of 2.3 ns. The component is housed in a 208-pin PQFP package.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation for both core and I/Os, ensuring PCI compliance.
• Enables deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Includes unique in-system diagnostic and verification capabilities via Silicon Explorer II.

Applications

• High-speed controllers and address decoding systems.
• Peripheral bus interfaces and DSP functions.
• Co-processor applications requiring high performance.

Procurement Notes

Verify the specific suffix 'M' against official datasheets to confirm temperature range and RoHS status, as variations exist within the MX family. Confirm end-of-life status and last-time-buy dates through authorized distributors, as this component may be subject to discontinuation notices.

Selection Notes

Select this model for designs requiring 54K system gates in a 208-pin plastic QFP package. Ensure voltage requirements align with the 3.3V or 5.0V operating specifications. Consider the 71 MHz speed grade if higher performance is needed, or verify if lower speed grades suffice for cost optimization.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, designed as cost-effective solutions for consolidating complex logic. These devices bridge the gap between simple PLDs and large FPGAs, offering high performance with moderate gate counts suitable for mid-complexity embedded applications.

Replacement Considerations

Direct replacements include other variants within the A42MX36 series such as A42MX36-1PQG208 or A42MX36-PQG208M, provided the package type and speed grade match. Verify pin compatibility and electrical characteristics before substitution.
