Microcontrollers Procurement Notes

Verify the specific suffix 'I/SO' corresponds to the industrial temperature range (-40°C to +85°C or +105°C) and SOIC package type. Confirm that the device variant matches the required pin count and memory size for your design constraints. Ensure compatibility with the intended power supply voltage range of 2.5V to 3.6V.

Microcontrollers Selection Notes

Select this component when a USB OTG interface is required alongside advanced analog capabilities like CTMU and comparators. It is suitable for designs needing high code density via MIPS16e mode and efficient power management in compact 28-pin packages. Consider alternative family members if higher clock speeds or larger memory capacities are needed.

Microcontrollers Part Context
