A42MX16-1PQ100I

Overview

The A42MX16-1PQ100I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 24,000 system gates and 608 Logic Elements within a PQFP-100 package. The device supports mixed-voltage operation with a core voltage of 3.3 V and I/O voltages ranging from 4.5 V to 5.5 V. It provides 83 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. The component utilizes Flash-based non-volatile memory technology for instant-on functionality.

Feature Summary

• Flash-based non-volatile architecture enabling instant-on configuration without external memory devices
• Supports mixed-voltage operation allowing integration of 3.3 V cores with 5 V I/O interfaces
• Provides deterministic timing through user-controllable pin locking and resource utilization

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interface implementations
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix '1' against official Microchip documentation to confirm speed grade and electrical characteristics, as standard listings often default to other variants like '-2'. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the PQFP-100 package availability aligns with current manufacturing data sheets.

Selection Notes

Select this model when a compact 100-pin solution is required for logic consolidation replacing multiple PALs or CPLDs. Compare against the A42MX16-VQG100I if a thinner VQFP profile is preferred over the standard PQFP height. Verify that the 83 available I/O pins meet the interface requirements for the target application design.

Part Context

This component belongs to the A42MX16 series within the broader MX FPGA portfolio. It shares architectural similarities with the A42MX09 and A54SX16P families but offers distinct gate counts and package options. The part represents a transition from legacy Actel designs now managed under Microchip Technology's programmable solutions division.

Replacement Considerations

Direct pin-compatible alternatives include the A42MX16-PQ100A for commercial temperature ranges or the A42MX16-2PQ100I for different speed grades. Verify functional equivalence regarding I/O drive strengths and power consumption before substitution.
