Application Specific Microcontrollers Procurement Notes

Verify the specific silicon revision and package variant against the datasheet Table 1-1 to ensure compatibility with the intended board design. Confirm that the ordering suffix corresponds to the required temperature range and packaging format as defined by Microchip Technology.

Application Specific Microcontrollers Selection Notes

Select this component when a split-architecture EC solution or standalone I/O controller is required for mobile computing devices. Ensure the design utilizes the appropriate voltage domains (1.8V/3.3V) for GPIOs and interfaces. Verify that the available SRAM configuration meets the firmware storage requirements.

Application Specific Microcontrollers Part Context

This part belongs to the MEC170x series, which includes variants like MEC1701, MEC1703, and MEC1705. These devices share a common architecture but differ in package options (128-pin, 144-pin, 169-pin WFBGA) and specific peripheral counts such as ADC channels and GPIO availability.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC170x family include MEC1701Q-C1-SZ or MEC1705Q-C1-SZ, provided the pinout and peripheral requirements match the specific package type (144-WFBGA) and feature set.
