A42MX36-PQG208

Overview

The A42MX36-PQG208 is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 208-pin PQFP package. It provides approximately 54,000 system gates and 176 user-programmable I/O pins. The device supports dual-voltage operation with core voltages ranging from 3V to 3.6V and I/O voltages from 4.75V to 5.25V. It integrates up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications. The component is designed for mixed-voltage environments, offering deterministic timing and high resource utilization.

Feature Summary

• Single-chip ASIC alternative consolidating logic previously implemented in multiple PLAs, CPLDs, and FPGAs.
• Supports mixed-voltage operation allowing simultaneous 5.0V and 3.3V core and I/O configurations.
• Features fast wide-decode circuitry capable of address decoding within nanoseconds.
• Includes unique in-system diagnostic and verification capabilities via Silicon Explorer II.

Applications

• High-speed controllers and peripheral bus interfaces.
• DSP and co-processor functions requiring embedded memory.
• Address decoding and complex logic consolidation in industrial systems.

Procurement Notes

Verify current availability status as the A42MX series may be subject to end-of-life notices or production changes. Confirm RoHS compliance and specific temperature grade requirements against the latest manufacturer datasheet before procurement. Check for any recent PCN updates regarding assembly sites or software tool compatibility.

Selection Notes

Select this model when designing for mixed-voltage environments requiring both 3.3V and 5V logic levels on the same chip. Ensure the 208-pin PQFP footprint fits the PCB layout constraints. Verify that the 176 I/O count and 54K gate capacity meet the design complexity without excessive over-provisioning compared to smaller variants like the A42MX16.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, known for cost-effective 5V solutions. These devices serve as direct replacements for legacy discrete logic and lower-density programmable devices. The MX architecture emphasizes high performance and ease of integration through its single-chip solution approach.

Replacement Considerations

Direct pin-compatible substitutes within the same package include other speed grades of the A42MX36 series, such as A42MX36-1PQG208 or A42MX36-2PQG208, provided timing requirements are met. Cross-family migration to newer Microchip PolarFire or IGLOO2 devices requires schematic and firmware redesign due to architectural differences.
