A42MX16-VQG100

Overview

The A42MX16-VQG100 is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 24,000 system gates and 295 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V, compliant with PCI standards. It includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable delays. The component is housed in a 100-pin VQFP package and supports up to 83 user-programmable I/O pins.

Feature Summary

• High-density logic capacity suitable for replacing multiple discrete PLAs, CPLDs, and FPGAs
• Integrated configurable dual-port SRAM for fast data buffering and FIFO applications
• Mixed-voltage I/O capability supporting both 3.3V and 5.0V interfaces
• Deterministic timing architecture allowing precise control over signal propagation delays

Applications

• High-speed controller implementations
• Peripheral bus interface protocols
• DSP and co-processor acceleration functions
• Complex address decoding logic

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm voltage range and temperature grade. Ensure compatibility with existing PCB footprints for the 100-VQFP package. Confirm moisture sensitivity level handling requirements during assembly. Validate that the selected variant meets the necessary industrial or military certification standards if applicable to the end product.

Selection Notes

Select this model when a design requires moderate logic density with integrated memory resources. Consider the VQFP package for surface-mount applications requiring a compact footprint. Evaluate the mixed-voltage I/O options if interfacing with legacy 5V systems while utilizing lower voltage cores. Compare performance metrics against other MX family members if higher gate counts are anticipated.

Part Context

This component belongs to the Microsemi (now Microchip Technology) 40MX and 42MX FPGA families. These devices were engineered to provide cost-effective solutions for high-performance logic applications. The family is known for its ability to consolidate complex digital designs into a single chip, reducing board space and power consumption compared to multi-chip solutions.

Replacement Considerations

Direct pin-to-pin replacements within the same package may include other variants from the A42MX16 series, such as A42MX16-VQG100A or A42MX16-VQG100M, provided electrical specifications match. Verify functional equivalence regarding gate count and SRAM size before substitution.
