Microcontrollers Procurement Notes

Verify the specific package type matches the WLCSP25 designation in the ordering information table. Confirm that the voltage supply range aligns with the single power supply requirement of 1.65 V to 1.95 V. Ensure the application environment temperature falls within the specified operational limits for the WLCSP25 package.

Microcontrollers Selection Notes

Select this component when a low-cost 32-bit MCU is required for applications replacing 8/16-bit architectures. It is suitable for designs needing reduced code size and simple instruction sets. Consider the limited GPIO count and ADC channels if complex peripheral integration is anticipated.

Microcontrollers Part Context

This part belongs to the LPC11xxLVUK family, which offers scalable entry-level performance. The family shares common architectural features but varies in memory sizes and pin counts. This specific model represents the base configuration with minimal SRAM and a compact package option.

Microcontrollers Replacement Considerations

LPC1102LVUKZ is a compatible alternative within the same family offering increased SRAM capacity while maintaining identical package dimensions and core specifications.
