A42MX16-3VQ100

Overview

The A42MX16-3VQ100 is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin VQFP package. It provides 295 Configurable Logic Blocks (CLBs) and approximately 2,000 system gates. The device supports mixed-voltage operation with core voltages of 3.0V to 3.6V and I/O voltages of 4.5V to 5.5V. It features up to 83 user-programmable I/O pins, a maximum clock frequency of 48.24 MHz, and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Flash-based non-volatile architecture enabling instant power-up configuration without external memory.
• Supports mixed-voltage I/O interfaces compatible with both 3.3V and 5.0V logic standards.
• Includes configurable dual-port SRAM for high-speed data buffering and FIFO applications.

Applications

• Replacement for complex programmable logic devices (CPLDs) in industrial control systems.
• Interface bridging between different voltage domains in embedded hardware.
• Prototyping and low-volume production of custom digital logic circuits.

Procurement Notes

Verify the specific speed grade suffix '3' against official datasheets to confirm timing characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the 100-VQFP package dimensions match the target PCB footprint requirements.

Selection Notes

Select this model when a compact 100-pin solution is required for moderate logic density. Compare CLB counts and I/O availability against alternative MX series variants. Verify that the 48.24 MHz performance meets the system timing constraints.

Part Context

This component belongs to the Actel/Microchip MX FPGA family, designed as a high-capacity single-chip ASIC alternative. The series combines Flash technology with SRAM capabilities, offering deterministic timing and pin-locking features for secure designs.

Replacement Considerations

Direct substitutes include other MX series parts such as A42MX16-VQG100A or A42MX16-2PQ100A, provided the package type and speed grade are compatible. Verify pinout compatibility before substitution.
