Microcontrollers Procurement Notes

Verify silicon revision B3 compatibility when sourcing this component, as specific errata items apply only to current revisions. Confirm that the ordering suffix 'T' indicates tape-and-reel packaging suitable for automated assembly. Ensure design reviews address known silicon anomalies detailed in DS80000663, particularly regarding oscillator configurations and peripheral clock settings. Cross-reference the Device ID and Revision ID using MPLAB X IDE tools during production validation.

Microcontrollers Selection Notes

Select this part when system requirements demand high integration of memory and connectivity within a constrained pin count. Consider the 100-pin TQFP package for designs prioritizing surface-mount assembly ease without sacrificing peripheral availability. Evaluate the need for automotive qualification if deploying in harsh environments. Compare against other PIC32MZ variants based on specific interface needs, such as the presence or absence of Ethernet or USB Host capabilities.

Microcontrollers Part Context

This microcontroller belongs to the PIC32MZ Embedded Connectivity with Floating Point Unit (EF) family, designed for demanding embedded applications. It shares architectural similarities with other members like the PIC32MZ1024EFF100T-I/PF but differs in specific peripheral configurations and package options. The EF series emphasizes high performance and rich connectivity, positioning it above standard PIC32MX/MK lines in terms of computational throughput and integrated features.

Microcontrollers Replacement Considerations

Direct substitutes within the same family include PIC32MZ1024EFF100T-I/PF and PIC32MZ1024EFK100T-I/PF, depending on required peripheral sets. Verify pin-to-pin compatibility and software compatibility before swapping. Alternative packages like LQFP-144 exist for higher pin counts but require board redesign.

Microcontrollers FAQ

Does the PIC32MZ1024EFG100T-I/PF support remote wakeup via USB?

No, the USB module does not support remote wakeup through the USBRIE bit. USB descriptors must inform the host that the device does not support this feature.

What is the workaround for the SQI clock divider issue?

Set the CLKDIV bits to '0' and use the REFCLKO2 clock as the SQI base clock to avoid reception or transmission failures associated with the divider.

Can the temperature sensor be used for accurate readings?

No, the internal temperature sensor does not function according to the silicon errata documentation.
