Procurement Notes

Verify the specific suffix -GSR corresponds to the 16-pin SOIC package and commercial temperature range (-40°C to +85°C). Confirm that the component status is Not Recommended for New Designs (NRND) and assess long-term availability constraints before finalizing procurement plans.

Selection Notes

Select this model when a cost-effective 8-bit solution with integrated analog peripherals is required. Ensure the design accommodates the 2.2 V to 3.6 V supply range and utilizes the available GPIOs via the digital crossbar. Consider the NRND status if future production longevity is a primary constraint.
