A42MX16-3VQG100

Overview

The A42MX16-3VQG100 is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 295 Configurable Logic Blocks (CLBs) and approximately 24,000 system gates. The device operates with mixed-voltage support for both core and I/Os at 3.3V or 5.0V, ensuring PCI-compliant compatibility. It includes up to 2.5 kbits of configurable dual-port SRAM and supports up to 202 user-programmable I/O pins. The component is housed in a 100-pin VQFP package and offers deterministic timing with full resource utilization and pin locking capabilities.

Feature Summary

• Supports mixed-voltage operation for core and I/Os at 3.3V or 5.0V levels
• Includes configurable dual-port SRAM for flexible memory applications
• Provides deterministic, user-controllable timing with 100% pin locking

Applications

• High-capacity single-chip ASIC replacement designs
• Mixed-voltage interface logic bridging different voltage domains
• Systems requiring deterministic timing and full pin locking

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage grade and temperature range. Confirm package integrity and moisture sensitivity level prior to assembly. Ensure compliance with export control classifications such as ECCN 3A991D. Cross-reference ordering information with the manufacturer's current product status to avoid obsolete variants.

Selection Notes

Select this model when a design requires approximately 24,000 system gates within a 100-pin surface-mount footprint. It is suitable for applications needing mixed 3.3V and 5.0V I/O compatibility without external level shifters. Consider the CLB count and SRAM availability relative to the target logic complexity and data buffering requirements.

Part Context

This component belongs to the Microchip A42MX16 family, which provides high-density programmable logic in compact packages. The MX series is engineered to replace complex discrete logic or standard ASICs, offering reprogrammability and reduced time-to-market. The VQG100 designation indicates a specific thin quad flat pack variant optimized for space-constrained PCB layouts.
