A42MX16-3PQG100

Overview

The A42MX16-3PQG100 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a PQFP-100 surface-mount package. It provides 295 Configurable Logic Blocks (CLBs) and approximately 2,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of either 3.3V or 5.0V. It features up to 83 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM. The maximum clock frequency is specified at 48.24 MHz, with a CLB delay of 3.72 ns. The industrial temperature grade variant operates between -40°C and +85°C.

Feature Summary

• Supports mixed-voltage operation for both core logic and I/O interfaces, compatible with 3.3V and 5.0V standards.
• Integrates configurable dual-port SRAM to facilitate FIFO implementations and data buffering.
• Offers deterministic timing through user-controllable path delays and pin locking capabilities.
• Provides high resource utilization allowing for 100% logic and pin configuration flexibility.

Applications

• Single-chip ASIC replacement for low-to-medium complexity digital designs.
• Industrial control systems requiring robust programmable logic.
• Automotive electronics applications utilizing mixed-voltage interfaces.
• Military and aerospace systems requiring qualified plastic packages.

Procurement Notes

Verify the specific suffix against official datasheets to confirm temperature range and voltage specifications. Ensure compatibility with existing PCB footprints for the PQFP-100 package. Check for moisture sensitivity level requirements during storage and handling. Confirm availability of programming tools compatible with the MX FPGA family architecture.

Selection Notes

Select this model when 295 CLBs are sufficient for the design logic density. Choose the PQFP-100 package for standard surface-mount assembly processes. Consider the 3.72 ns CLB delay if timing constraints exceed 48.24 MHz performance limits. Evaluate the need for embedded SRAM before selecting this over pure logic devices.

Part Context

This component belongs to the Actel/Microchip MX series of flash-based FPGAs. It shares architectural similarities with the A42MX09 and A42MX24 variants within the same family. The device utilizes non-volatile flash technology, eliminating the need for external configuration memory commonly found in SRAM-based FPGAs.

Replacement Considerations

Direct substitutes include other members of the A42MX16 family with different speed grades or packages, such as A42MX16-2PQG100A. Cross-family replacements may require significant schematic and layout modifications due to differences in I/O counts and logic resources.
