A42MX16-1PQ100

Overview

The A42MX16-1PQ100 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin Plastic Quad Flat Package (PQFP). It contains 295 Configurable Logic Blocks (CLBs) and offers approximately 2000 equivalent system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB propagation delay of 3.72 ns. It operates within an industrial temperature range of -40°C to +85°C and utilizes mixed-voltage I/Os compatible with 3.3V or 5.0V standards.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.
• Features deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.

Applications

• High-speed controllers and address decoding systems.
• Peripheral bus interfaces and DSP co-processor functions.
• Mixed-voltage interface solutions requiring PCI-compliant I/O levels.

Procurement Notes

Verify the specific speed grade suffix against official datasheets, as variations exist within the A42MX16 series. Confirm package integrity and moisture sensitivity level (MSL 3) handling requirements prior to assembly. Cross-reference the manufacturer part number with current Microchip Technology documentation to ensure component authenticity and specification accuracy.

Selection Notes

Select this model when design requirements fit within 295 CLBs and 2000 system gates. Ensure the 48.24 MHz performance meets timing constraints. Verify that the PQFP-100 footprint aligns with PCB layout specifications. Consider higher gate counts if complex logic consolidation is necessary beyond this capacity.

Part Context

This component belongs to the Microsemi (now Microchip Technology) 40MX and 42MX FPGA families. These devices are designed as cost-effective single-chip solutions to replace discrete programmable logic. The MX series emphasizes high performance and ease of integration through mixed-voltage operation and extensive I/O flexibility.

Replacement Considerations

Compatible substitutes include other variants within the A42MX16 family, such as A42MX16-2PQ100A or A42MX16-PQG100I. Verify that the replacement part matches the required operating temperature range and voltage specifications before implementation.
