A42MX16-FPQ100

Overview

The A42MX16-FPQ100 is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip 40MX and 42MX families. It provides up to 54,000 system gates and integrates up to 2.5 kbits of configurable dual-port SRAM. The device supports mixed-voltage operation with 5.0V or 3.3V core and I/Os, featuring PCI-compliant interfaces. Key performance metrics include a maximum clock frequency of 250 MHz, 5.6 ns clock-to-out delay, and 5 ns dual-port SRAM access time. It offers up to 202 user-programmable I/O pins and deterministic timing with 100% resource utilization and pin locking capabilities.

Feature Summary

• High-capacity single-chip ASIC alternative with extensive logic resources
• Integrated configurable dual-port SRAM for fast data buffering
• Mixed-voltage operation supporting both 5.0V and 3.3V standards
• Deterministic timing with full resource utilization and pin locking

Applications

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

Procurement Notes

Verify the exact suffix 'FPQ100' against official Microchip documentation, as standard family listings typically specify PQFP or VQFP packages. Confirm moisture sensitivity level and operating temperature range requirements before procurement. Ensure compatibility with existing design tools and programming cables for the MX FPGA family.

Selection Notes

Select this component when designing systems requiring high gate density in a plastic QFP package. Consider the 40MX/42MX family features such as wide-decode circuitry and JTAG boundary scan testing. Evaluate power consumption and thermal dissipation characteristics suitable for commercial, industrial, or military environments depending on the specific grade required.

Part Context

This part belongs to the Microchip 40MX and 42MX FPGA families, which are designed as cost-effective solutions for consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs. The series is known for shortening system design cycles while providing high performance and flexibility for complex digital applications.

Replacement Considerations

Direct substitutes within the same package may include other variants from the A42MX16 series with different speed grades or temperature ranges. Cross-family replacements might involve higher-density devices from the SmartFusion or IGLOO2 families, though pinouts and architecture will differ significantly.
