Application Specific Microcontrollers Procurement Notes

Verify the specific silicon revision and datasheet version (DS00002206H) prior to procurement. Confirm that the -I suffix corresponds to the industrial temperature range requirements for the target application environment. Ensure compatibility with the intended host interface configuration.

Application Specific Microcontrollers Selection Notes

Select this model when both LPC and eSPI host interface support are required within the MEC170x family. Verify that the 144-pin WFBGA package dimensions fit the PCB layout constraints. Check if the 480KB SRAM capacity meets firmware storage needs compared to lower-capacity variants in the series.

Application Specific Microcontrollers Part Context

This component belongs to the MEC170x family of keyboard and embedded controllers manufactured by Microchip Technology. It shares the same core architecture and feature set as other members like the MEC1701 and MEC1703, differentiated primarily by package type, pin count, and specific peripheral availability.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC170x family include MEC1701Q-C1-SZ or MEC1703Q-C1-SZ, provided the pinout and peripheral requirements match. Verify that the substitute part supports the necessary host interfaces and memory sizes.
