A42MX16-2PQ100

Overview

The A42MX16-2PQ100 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin Plastic Quad Flat Package (PQFP). It features 295 Configurable Logic Blocks (CLBs) and approximately 2,000 equivalent system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. Operating temperatures range from -55°C to +125°C for military-grade variants. Key specifications include up to 2.5 kbits of configurable dual-port SRAM, mixed-voltage I/O support (3.3V or 5.0V), and compliance with JTAG boundary scan standards.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• Mixed-voltage operation capability supporting both 3.3V and 5.0V core and I/O configurations
• Integrated diagnostic and verification capabilities via Silicon Explorer II technology

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• DSP and co-processor functions
• Military and aerospace applications requiring MIL-STD-883 certification

Procurement Notes

Verify the specific suffix code against official Microchip documentation to confirm temperature grade and package variant. Ensure compatibility with existing PCB footprints for the PQFP-100 form factor. Confirm moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this component when deterministic timing and high reliability are required over raw gate count. Consider the trade-off between the 2,000-gate capacity and the availability of embedded SRAM. Verify that the 48.24 MHz performance meets system speed requirements compared to higher-speed alternatives in the MX family.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, designed as cost-effective solutions for consolidating complex logic designs. These devices bridge the gap between simple programmable logic and larger FPGAs, offering high performance at lower power consumption levels suitable for space-constrained applications.

Replacement Considerations

Direct substitutes within the same package and functionality include the A42MX16-2PQG100A and A42MX16-2PQ100A. Verify electrical characteristics and temperature ranges match before substitution.
